Chapter 4 Key emerging issues: insurance, planning and legal matters
relating to the coastal zone
we know we are heading for trouble in terms of more
exposure to extreme weather events and we will need to upgrade our building
standards. The Insurance Council does meet with us occasionally and their
constant request is that we do this. Their argument is that if we do not have
higher minimum standards then insurance will become unaffordable for
communities because damage will be so frequent and expensive.[1]
At present there is a high degree of uncertainty in
relation to current and future climate change liability. If left unaddressed
this uncertainty will continue to have a significant impact on decision making
processes and information disclosure in relation to climate change hazards.[2]
Introduction
4.1
Chapter 4 looks at some key emerging issues relevant to the coastal zone
relating to insurance, planning and legal matters. These issues were frequently
raised by inquiry participants over the course of the inquiry, particularly in
the context of projected climate change impacts on the coastal zone.
Climate change and coastal insurance issues
4.2
The insurance industry helps manage society’s risk from weather
related damages. In Australia, ‘19 of the 20 largest
property insurance losses since 1967 have been weather related’. Insured losses from these events are ‘expected to total
billions of dollars’:
Between 1967 and 1999, bushfires cost the Australian economy
around $2.5 billion. From 1960 to 2001, there were 224 fire-related deaths and
4505 injuries.
The 1999 Sydney hailstorm resulted in $1.7 billion in insured
losses, 1 death and 500 injuries. 500 people were
made homeless, and 24,000 homes and 70,000 motor vehicles were damaged.[3]
4.3
It is in this context that general insurance products provide essential
risk cover for Australians:
The industry provides a financial recovery mechanism from
weather related catastrophes by evaluating, pricing and spreading the risk of
such events, and then paying claims when they arise.[4]
4.4
Climate change is projected to have a major impact on the frequency of
extreme weather events, with the coastal zone being particularly vulnerable in
this regard because of the combined effects of sea level rise and storm
surge/flooding events. In its submission to the inquiry, the peak body for the
insurance industry, the Insurance Council of Australia (ICA),[5]
noted that:
more than 425,000 Australian addresses are below 4 metres
above mean sea level and within 3km of the current shoreline. Within the
Greater Sydney region (Newcastle to Wollongong), 46,000 addresses are
identified as being within 1km of the shoreline and with elevations less than
3m.[6]
4.5
The ICA further observed that the majority of these vulnerable addresses
are located near ocean-connected coastal waters—that is, alongside lakes, river
banks and estuaries—and that properties in coastal settlements which are also
on inland floodplains ‘can be liable to both river and ocean inundation, often
concurrently’.[7]
4.6
Climate change could have adverse impacts on insurance affordability and
availability, compounding the problem of under-insurance:
Around 23 per cent of Australian households (1.8 million) are
currently without building or contents insurance. As insurance premiums rise,
more households may opt out of insuring, putting an added burden on governments
and communities when disasters occur.[8]
4.7
A number of submissions to the inquiry noted concerns about insurance
coverage for coastal areas: ‘I think inevitably we are going to see major
changes in the extent to which the insurance industry is prepared to cover
these properties in the future’.[9] In particular, the
Queensland Government commented that:
There are growing concerns that the scope of insurance
coverage is being reduced in some coastal areas of Australia because of climate
change, particularly the increased threat of sea inundation and riverine flooding.
There are already examples from Britain and the United States where insurance
had been withdrawn or not been renewed in areas deemed prone to climate change
impacts. If insurers come to the conclusion that some areas are not insurable
then these communities will have a greater reliance on government relief,
ultimately placing an additional burden on government and tax payers.[10]
4.8
Against this background, the Committee was particularly interested in
identifying any emerging gaps in insurance coverage for the coastal zone[11]
and what action might be taken by the Australian Government and the insurance
industry to address this matter.
Gaps in insurance coverage for the coastal zone
4.9
The ICA confirmed that there are ‘presently no red flagged areas for
insurance in a geographic sense that [they] are aware of’.[12]
No regions in Australia are therefore currently ‘completely red-flagged’—in the
sense that no insurance products are available:
insurers do adjust their risk profiles according to the
history of loss in a region. If there is a high level of loss in a region, they
would start to increase the cost of offsetting that risk. Some insurers may
actually adjust their presence in a region, and by that I mean actually ceasing
to write new policy in a region. That has happened around the world. An insurer
might decide that they have had enough policy exposure in that region and are
now going to focus on another market.
Are we seeing that in Australia? While there are micro
adjustments all the time for insurers prudentially spreading their risk right
across the nation, we are not seeing any huge trend at the moment where we
might start to see areas that are red flagged, unable to get insurance or
anything of that nature. There is still a good level of competition in the
market ...
I think you will find that insurance will remain available in
all areas.[13]
4.10
However, the ICA further clarified that, even though ‘no areas are
completely red-flagged’, there are some things ‘that you cannot insure for
presently in Australia’.[14] Risks identified by ICA
as not generally covered by insurance or as ‘presently difficult to insure
against’ include ‘Storm Surge, Landslip and Sea Level Rise’.[15]
4.11
In terms of storm surge, Mr Sullivan from the ICA commented that:
There are some insurers who will look at what are more
commonly called saltwater risks. That could be a king tide on top of a storm
surge on top of a coastal inundation problem. So I think the trend is there—the
market is starting to look at those risks—but presently, no, you cannot get
cover for that in any significant or competitive way.[16]
4.12
In terms of landslip, the Committee drew Mr Sullivan’s attention to some
images of coastal erosion affecting properties at North Entrance on the Central
Coast, NSW,[17] and queried whether
coastal erosion of this sort is categorised as landslip and therefore not
covered under insurance policies. Mr Sullivan responded as follows:
Presently not covered—that would be a landslip issue or a
coastal erosion issue. You can see that with the level of exposure in Australia
or the number of properties in that kind of predicament, that would be a very
difficult product to develop, price and find a market for. So the person would
still be able to get insurance for the house burning down, a burglary, storm
damage and that sort of thing, but, in general, you would not be able to find a
policy to cover you for a landslip issue like that. I would not envisage that
changing into the future.[18]
Example
of coastal dune erosion, North Entrance, Central Coast, NSW—see Submission 5
4.13
In terms of sea level rise, Mr Sullivan commented that:
You simply cannot get an insurance product at the moment for
gradual sea level rise that at a future time prevents you using a parcel of
land because it has become untenable ... globally that is not covered anywhere
at the moment. Our most recent study shows there are 896,000 residential
properties below six metres and within 3,000 metres of existing coastline, so
that is a significant exposure that is out there.[19]
4.14
The Committee understands that a further complication here is that the
definitions of these risks ‘vary between insurers’.[20]
However, in this context, it is important to note that ‘there are no common
definitions adopted within the general insurance industry on risk’.[21]
4.15
The ICA provided some examples of general exclusions in various policies
relating to saltwater risks or action of the sea. Examples included:
We will not pay for damage caused by erosion or
subsidence—Caused by or as a result of erosion, vibration, subsidence,
landslip, landslide, mudslide, collapse, shrinkage or any other earth movement
and
We will not pay for damage caused by actions or movements
of the sea
and
We will not pay for Loss, damage, injury or death arising
from:
n Actions of the
sea, high water or tidal wave—unless the loss or damage is the result of a
tsunami
n subsidence or
landslide unless it happens immediately as a result of an earthquake or
explosion
n hydrostatic
pressure including loss or damage to swimming pools or similar structures.
and
We will not pay for damage caused by:
n the seas or tidal
wave;
n river flood; ‘river
flood’ means when water that is normally contained in a water catchment system increases
because of rainfall or snow melt (whether in the immediate region or elsewhere)
or is deliberately released by an authority, and the water overflows onto land
that is not normally covered by water into your home.
n erosion or earth
movement ... ‘earth movement’ means heavage, landslide, land-slippage,
mudslide, settling, shrinkage or subsidence ... ‘erosion’ means being worn or
washed away by water, ice or wind.[22]
4.16
The ICA further noted that:
The majority of policies use planning language terms such as
damage or loss caused by any actions or movements of the sea. Some insurers go
further in defining damage from the sea that arises from sea level rise from
storm or cyclone events.
Geotechnical issues may be variously defined by some insurers
using plain terms such as damage or loss caused by erosion, landslide,
collapse, vibration, settling, expansion, shrinkage or any earth movement
(generally other than earthquake, which is often defined as a separate event).
The Insurance Council does not hold precise statistics
regarding the prevalence or otherwise of exclusions on these matters. However,
a scan of publicly available Product Disclosure Statements indicates that cover
for damage or loss caused by action or movement of the sea is available in the
Australian market, with some restrictions on the types of damage that will be
covered as a result of the event. The majority of policies exclude, or have
pre-defined limits on the extent of cover, for damage or loss caused by
geotechnical matters which are defined using various plain language terms.[23]
4.17
Clearly, where land is inundated or eroded by rising sea levels, coastal
landowners and lenders in the banking and finance sector could face significant
losses:
Preliminary estimates of the value of property in Australia
exposed to this risk range from $50 billion to $150 billion. The figure depends
upon the extent of sea level rise assumed (in the order of 1 metre to 3
metres) and the effectiveness or otherwise of potential mitigation measures.
Even if paid for over 50 years this amounts to a cost to replace those assets
of some $1 billion to $3 billion per annum in real terms.[24]
4.18
Given the estimated scale of economic exposure here, the Committee
emphasises that insurance coverage of storm surge, landslip and sea level rise
events is therefore a significant emerging issue that needs to be examined
further. As one individual informed the Committee, with regard to insurance
coverage when their home had to be demolished because of coastal erosion:
Nil coverage. See clause 34: anything from the sea, nothing
at all ... No help with demolition.[25]
Insurance industry recommendations to government
4.19
At a broader level, the ICA outlined a number of ‘key actions’ for
governments to improve community resilience to extreme weather events—see
Figure 4.1. While many of these key actions are relevant to all regions of
Australia, they are particularly relevant to coastal communities, given the
high exposure of the coastal zone to climate change risk.
4.20
In its submission to the inquiry, the Insurance Australia Group (IAG)[26]
noted that ‘Australia faces an “insurance gap” because land values are not
currently insured’.[27] Land value forms a
significant component of a property’s overall value in coastal locations.
However, whereas ‘the value of coastal buildings may be protected to some
extent by insurance, the land value of properties is not insured at all’.[28]

Submission 12
4.21
IAG recommended that the Australian Government consider the development
of a coastal land value insurance scheme to manage risks in this area. This
would involve establishing an insurance fund into which owners of low-lying
coastal land would ‘pay a regular levy so as to provide compensation when
rising sea levels cause their land to become permanently unusable’:
Such a scheme could be operated by government alone, or in
conjunction with the private sector. IAG considers that, for several reasons,
it is unlikely to be feasible for the private insurance sector alone to operate
such a scheme. Most importantly, the globally synchronized nature of the risk
of rising sea levels eliminates the scope for geographic diversification of
risk on which insurers and global reinsurers normally rely.
An appropriately designed scheme of this nature would
introduce a ‘user pays’ price signal to owners of vulnerable waterfront land
that they should be responsible for funding the cost of potential compensation
payable to them should that land become unusable rather than expecting future
compensation to come from some other source.[29]
Conclusion
4.22
The Committee understands that a changing, less predictable climate has
the potential to reduce insurers’ capacity to assess, price and spread
weather-related risk, particularly in the coastal zone, and have adverse
impacts on insurance affordability and availability. The Committee also
appreciates that appropriate action needs to be taken by government and the
insurance industry to improve community resilience to extreme weather events.
4.23
For example, the IAG pointed to the ‘crucial role of government in
providing a comprehensive and clearly defined regulatory framework that
promotes community resilience to risk and facilitates more affordable premiums
and more predictable claims costs’.[30]
4.24
As discussed, the Australian Government is providing leadership in this
area through the National Climate Change Adaptation Framework, which is in the
early stages of implementation.
4.25
That said, however, the Committee is not aware of any specific work
having been undertaken or currently being undertaken by the Australian
Government relating to insurance coverage in the coastal zone.
4.26
The Committee notes the importance of the insurance industry in managing
society’s risks from weather related damages and therefore the increasing
significance of this sector, given the projected impacts of climate change. The
Committee also notes the significant exposure of coastal regions to climate
change risks such as storm surge, landslip and sea level rise.
4.27
Given the complex nature of this issue and the potentially significant
social and economic costs involved, the Committee believes further
investigation of this important matter is urgently required.
4.28
As the ICA emphasised, ‘the significant implications for the Australian
economy that flow from this hazard require serious consideration and
treatment.’[31]
Recommendation 19 |
|
The Committee recommends that the Australian Government
request the Productivity Commission to undertake an inquiry into the
projected impacts of climate change and related insurance matters, with a
particular focus on:
n insurance coverage
of coastal properties, given the concentration of Australia’s population and
infrastructure along the coast
n estimates of the
value of properties potentially exposed to this risk
n insurance
affordability, availability and uptake
n existing and
emerging gaps in insurance coverage, with a particular focus on coverage of
coastal risks such as storm surge/inundation, landslip/erosion and sea level
rise (including the combined effects of sea inundation and riverine flooding)
n the need for a
clear definition of the circumstances under which an insurance claim is
payable due to storm surge/inundation, landslip/erosion and sea level rise,
as well as due to permanent submersion of some or all of the land
n the possibility of
a government instrument that prohibits continued occupation of the land or
future building development on the property due to sea hazard
n gaps in the
information needed to properly assess insurance risk and availability of
nationally consistent data on climate change risks
n examining the key
actions for governments proposed by the Insurance Council of Australia and
the Insurance Australia Group in their submissions to this inquiry
n possible responses
to a withdrawal of insurance for certain risks or regions, noting the
increased burden this could place on government and taxpayers |
Climate change and coastal planning issues
4.30
Land use planning is a complex area that touches on a broad range of
issues relating to the environment and ecologically sustainable development,
governance and institutional arrangements and, more recently, climate change
impacts.
4.31
Over the course of the inquiry, the Committee observed substantial
changes in the updating of state and local planning schemes to include specific
provisions for climate change impacts and adaptation strategies. For example,
in a 2008 study, the Australian Network of Environmental Defender’s Offices
(ANEDO) identified that ‘only 7 pieces of Commonwealth and NSW legislation
mention climate change’.[32] Similarly, in its June
2008 submission, the National Sea Change Taskforce (NSCT) commented that:
While climate change is increasingly recognised by
Commonwealth and State governments in Australia as a critical issue for coastal
communities, few local planning schemes include specific provisions for climate
change adaptation.[33]
4.32
As Dr Church, from the Commonwealth Scientific and Industrial Research
Organisation (CSIRO), commented to the Committee:
Much of our previous planning has been done in a stable
climate where sea level and other properties have not been changing. We are no
longer in that situation, and different planning views need to be taken.[34]
4.33
Legal imperatives, as discussed below, are also ensuring that planning
schemes across Australia are gradually being revised to take into account
projected climate change impacts.
4.34
Of particular interest here is the extent to which coastal planning
schemes promote decisions that increase resilience to the impacts of climate
change and discourage decisions that increase vulnerability. As a number of
submissions to the inquiry emphasised:
There is pressing need to reconsider how we plan for coastal
development, the criteria we apply to approve or reject development
applications and the building regulations imposed for new structures to
safeguard against risks of sea effects on coastal assets. These revisions will
not be simple recasting of existing instruments but will need to be dynamic in
nature to take into account the fact that the points of reference for planning
(e.g., height above sea level, frequency of extreme sea levels) are now
constantly changing and will continue to change for the foreseeable future. It
is likely that appropriate guidelines, approval criteria and building
regulations will necessarily be more complex than the existing, familiar, standards.[35]
State coastal planning policies
4.35
A key point to emphasise at this point is that planning is a state
responsibility. The Australian Government ‘provides significant financial
assistance to local government but does not have jurisdiction over local government
operational decisions, including their planning decisions.’[36]
4.36
Some inquiry participants called for the Australian Government to
provide national leadership and consistency in this area:
While land-use planning is a responsibility of the States and
Territories, NSW considers a more collaborative and supportive relationship
across all levels of government could assist in delivering targeted and
economically appropriate regional responses to the impacts of climate change on
Australia’s coastal communities.[37]
a nationally coordinated program [is required] to encourage
states and territories to undertake a systematic review of all environmental
planning instruments and legislation to ensure that adequate and nationally
consistent approaches to consideration of climate change through development
assessment.[38]
LGAT recommends a nationally consistent approach to planning
policy and management, including set back provisions in coastal areas.[39]
4.37
However, as Mr Beresford-Wylie, Chief Executive of the Australian Local
Government Association (ALGA), emphasised, national leadership and consistency
on this issue:
does not necessarily mean the Australian government coming
down with a model that is imposed ... National consistency can be read not so
much as saying that the Australian government should be engaged but as saying
that there should be a greater degree of consistency between the jurisdictions
in how they deal with the issues facing councils and the planning on the
coastal zones.[40]
4.38
Inquiry participants raised a number of concerns about state coastal
planning policy and its treatment of climate change—in particular, that in some
cases ‘planning legislation and the policy framework had not kept up to date
with current issues and information on climate change’[41]
and that there are variations between state governments in terms of the levels
of guidance provided to local government about how to deal with coastal
planning issues and projected climate change impacts:
One of the things that we do find in local government—which
is perhaps a little bit unfortunate—is that in the absence of consistent
guidance from states about how to deal with coastal planning issues,
particularly climate change, well-resourced councils will go off and do their
own thing. They will try and fill the gap in and they will do the best they can
by their communities and their environment. That does lead to criticism by
those who have an interest—in, for instance, development on the coast—that
there is no consistency between councils in the way these things are done.[42]
4.39
The Planning Institute of Australia (PIA) had a particular interest in
this area and highlighted its concerns that:
n Planners will be
faced with increasingly difficult land use and development scenarios reflecting
population and settlement trends which will need to be managed within the
context of climate change issues to reduce vulnerability [of] coastal
communities and individuals and the environment
n Planners will be
under pressure to manage coastal and hinterland areas in new ways in the future
which may impact on the way that the community has traditionally used such
spaces/places
n PIA and planners
generally will be key agents for awareness raising and capacity building in the
community generally and within this peak profession[43]
State sea level rise planning benchmarks and risk management framework
4.40
The rate of projected rise in sea level is critical for estimating the
severity of potential impacts, and several state governments have recently
established sea level rise benchmarks in their coastal planning policies, to
serve as guidance in this area—see Figure 4.2.
4.41
Several inquiry participants called on the Australian Government to
provide a national benchmark for sea level rise:
there is an emerging need for an agreed sea level rise
benchmark figure for planning purposes in Australia ... State and local
governments would benefit from guidance as to what range of sea level rise
would be considered most appropriate for planning purposes. Without such
guidance, there will be inconsistency across jurisdictions in the application
of sea level rise projections. The Queensland Government is therefore seeking
the development of a set of nationally consistent default climate change
scenarios for use in planning, particularly for sea level rise.[44]
Coastal communities may benefit from nationally consistent
parameters for key indicators, including ... sea level rise (coastal
inundation), where regional idiosyncrasies do not militate against such an approach.[45]
I was somewhat surprised, as a lot of other people were, to
find the differences between projected sea level rises in different states all
around Australia ... It goes to the heart of why there is a need for some
collaborative national approach to address an issue as fundamental as the
projected sea level rise by, say, the year 2100 ... I think that clearly
demonstrates the need for greater cooperation and coordination between the
jurisdictions, the states and territories, but also in a process which is
initiated by the Commonwealth. I do not see that any other jurisdiction is in a
position to be able to initiate that process.[46]
There are a range of opportunities for action where the
Federal Government could assist states/territories [including] adopting a
consistent sea level rise scenario across jurisdictions.[47]
The reason that I was proposing that there be some national
consistency in respect of agreement around what level of sea level rise needs
to be planned for—for example, New South Wales is saying 0.9 metres by 2100,
Victoria is suggesting 0.8 metres, Queensland is still considering its position
and so on—is that it is much easier for everyone to communicate the risk if
everyone is obliged to communicate it and they are communicating the same level
of risk.[48]
Another good area that we perceive could be dealt with on a
national basis is, of course, what sea level scenarios and other climate change
related scenarios we adopt for the coast. States are certainly going it alone
at the moment. Some have been doing it for quite some time. Others are still
getting on board. Some do not have any guidelines in their state planning
policies at all. All of the numbers are different, well beyond what you would
expect for regional variations across the country.[49]
Figure 4.2 Sea level rise benchmarks in state coastal
planning policies
South
Australia
The Coast
Protection Board (2002) has adopted the median sea level predictions of the
IPCC as part of its coastal planning policy—0.3m sea level rise by 2050, and 1 metre
sea level rise by 2100. For major developments, the full range of possible
climate change impacts should be considered.
Tasmania
Tasmania has
developed an approach based on a 1% annual exceedance probability; that is the
probability of a high sea-level event having a 1% chance of occurring once or
more in any one year (2008). To determine exceedance probabilities Tasmania
coastline is classified into a number of ‘tidal zones’ and sea level rise
projections are based on the IPCC’s upper emissions scenarios (A1FI). For any
given height of a location, the risk of a high sea level event flooding that
point can be determined and the risk over time (up to 2100) can also be
identified.
Queensland
The State
Coastal Management Plan (2002) identifies climate change adaptation principles
that should be referenced in coastal planning. In assessing coastal erosion
prone areas, a 0.3m rise in sea level over a 50 year planning period
should be adopted (2005).[50]
Western
Australia
The State
Coastal Planning Policy (2006) suggests that coastal planning strategies should
take into account coastal processes and sea level change. The Policy provides
for a benchmark of 0.38m when assessing the potential for erosion on sandy
shores.
Victoria
The Victorian
Coastal Strategy (2008) provides a policy of planning for sea level rise of not
less than 0.8m by 2100.
New South
Wales
The draft Sea
Level Rise Policy Statement (2009) indicates a sea level rise benchmark of 0.4m
by 2050 and 0.9m by 2100, should be adopted in coastal planning.

Climate Change Adaptation Actions for Local Government, Report by SMEC
Australia, 2009, p. 57
4.42
Dr John Hunter, from ACE CRC, suggested that a national framework for
planning for sea level rise might be more useful than a national benchmark:
we need to coordinate the ways in which we go about planning
and policy making around Australia. It does not mean that we pick the same
numbers but that we have the same framework by which we choose those numbers so
that the developers would actually know what they are going to do when they go
to a different part of Australia and there is just one uniform way of doing
these things.[51]
4.43
Dr Andrew Ash, Director of the CSIRO Climate Adaptation Flagship,
similarly commented that ‘we get fixated on picking a number. We should really
be taking a risk management approach rather than saying that that is the number
and that we plan to that number’.[52] Professor Woodroffe also
noted that ‘[n]o single value is likely to apply across the nation, but a
framework is needed within which such an issue is considered’.[53]
4.44
The Committee agrees that it is crucial that the Australian Government
provide national leadership in this area to resolve these issues relating to
the establishment of a sea level rise benchmark and planning framework.
4.45
Dr John Church, from CSIRO, made the important point that sea level rise
planning benchmarks need to be part of a risk management framework:
Like all other aspects of managing our economy and our
environment, to combine these different issues, particularly the extreme events
such as the storm surges and the cyclones, with the sea level rise is a risk
management issue and needs to be put in a risk management framework ...
sea level rise will not stop in 2100. This is a time-evolving
issue, and that requires us to change our thinking rather than specify a single
number ... If you are building a changing shed, which has got a lifetime of 10
years, then you do not need to plan for 2100 when you are building that; but if
you are building a city, which is going to have a much longer lifetime, then
that number might be too low ... It is the different lifetimes of different
infrastructure and the different risks associated with different infrastructure
that I think we need to be a little more sophisticated about.[54]
4.46
Dr Hunter similarly observed that:
One problem we have is that planners tend to come to us and
say, ‘How much do we need to allow for sea level rise?’ The retort I always
give is, ‘What kind of risks do you want to take?’ I think this is a very
important change in process that we need: to put the onus of the risk back onto
the planners and the policymakers, not leave it to the scientists. What we can
tell you is that if you build something at a certain height, when we take all
the uncertainties into account this then is the probability that you will be
flooded during the life of the asset that you have built ... We cannot make the
decision about what risks you want to take. We can make the decision about what
the probability of something happening is ...
we really have to move into a risk assessment framework ...
where we talk more about probabilities and the risks that we are prepared to
take ...
It is a matter of deciding what the risk is that you want to
take and then deciding on a number, rather than just picking one number.[55]
4.47
A risk management approach takes the IPCC sea level rise projections as
a starting point and integrates these with information on local sea level
history. As Professor Steffen commented:
I am generally very conservative on using projections. I
would rather take an approach in terms of assessing vulnerability and planning
adaptation. That is often referred to as a bottom-up approach. In other words,
put the emphasis on the local region: what is its adaptive capacity; where are
its vulnerabilities now; does it have a very low-lying shallowly angled
coastline that is prone to inundation now, or does it have more rocky headlands
and so on? You have got to sort that out first ...
I would prefer to see the government give probability ranges
rather than best guesses ...
That is the sort of information I would like to give. What I
would not like to give is: here is a median scenario—it came out of the black
box of climate modelling—use this ... Most people are used to dealing with
economic data that way because you cannot predict how an economy is going to
go. The same is true with climate change. There are large uncertainties there.[56]
4.48
Coastal planning guidelines have traditionally been based on a notion of
static sea level both now and into the future, and that prior experience of
extreme sea levels is therefore a good indicator of future risk. Planning and
development guidelines for most coastal regions generally refer to expected
return periods for ‘unusual’ sea level extremes—that is, the 1 in 100 year
event.[57] However, as part of a
climate altered future, high sea level extremes will become more frequent.
Accordingly, even a modest rise in sea level would mean that events that happen
only once a year now will happen every day by 2100, and 100-year events would
happen annually:
if you have a flooding event which only happens every year at
the moment, by the end of the century it will be happening about every day ...
if we design things on the shoreline which we think are only going to get
flooded once every 100 years, with a sea level rise of half a metre these
events will be happening every few months ...
We tend to work to the 100-year return period, which is that
you design things so that there is only going to be an event once every 100
years on average.
When you build in the uncertainty of the sea level rise
estimates ... the statistics of just assuming things are going to come along at
a regular rate just falls down. Instead of working in terms of how often you
think things are going to happen, you have to ask the question: what is the
probability of something happening during a certain time period? So you have to
change the way in which most of these planning regulations are phrased.[58]
4.49
The Committee notes the serious implications of these more frequent
flooding projections for coastal planning and the need for urgent action to
amend coastal planning and development policies.
4.50
The Department of Climate Change has funded ACE CRC to develop an interactive
web-based tool to enable planners, engineers and policymakers to incorporate
IPCC projections of sea level rise into local scale planning codes.[59]
This initiative seeks to statistically combine recorded variations in today’s
sea level (through tides, storms and other meteorological events) with
internationally IPCC agreed projections of future sea level rise. As
Dr Hunter further explained:
We are combining the uncertainties of the present flooding
events—that is, the fact that we do not know when the next storm is going to
come or how big it will be. We have observations of the statistics of those
from records that have been kept in ports over the last century. We are
combining those statistics with the uncertain projections of sea level rise in the
future, and in combining those statistics we can come up with numbers that will
tell us, if we build at a certain level and expect something to last from, say,
2010 to 2050, what is the probability of a flooding event during that period.[60]
4.51
This information can be used by engineers and planning authorities to
set risk guidelines for coastal development and infrastructure maintenance. The
Committee notes that the ACE CRC has also been conducting a national program of
workshops based on this research, targeted at infrastructure owners, planners,
engineers and policymakers. The workshops provide training on this web-based
tool.[61]
4.52
The Victorian Coastal Strategy sets out a comprehensive policy for
incorporating climate change into coastal planning—see Figure 4.3. Tasmania
also has comprehensive documentation supporting its sea level rise planning
policies.[62]
Figure 4.3 Victorian Coastal Strategy 2008: coastal
planning policy
1.
Plan
for sea level rise of not less than 0.8 metres by 2100, and allow for the
combined effects of tides, storm surges, coastal processes and local
conditions, such as topography and geology when assessing risks and impacts
associated with climate change. As scientific data becomes available the policy
of planning for sea level rise of not less than 0.8 metres by 2100 will be
reviewed.
2.
Apply
the precautionary principle to planning and management decision-making when
considering the risks associated with climate change.
3.
Prioritise
the planning and management responses and adaptation strategies to vulnerable
areas, such as protect, redesign, rebuild, elevate, relocate and retreat.
4.
Ensure
that new development is located and designed so that it can be appropriately
protected from climate change’s risks and impacts and coastal hazards such as:
§ inundation by
storm tides or combined storm tides and stormwater (both river and coastal
inundation)
§ geotechnical
risk (landslide)
§ coastal
erosion
§
sand
drift.
5.
Avoid
development within primary sand dunes and in low-lying coastal areas.
6.
Encourage
the revegetation of land abutting coastal Crown land using local provenance
indigenous species to build the resilience of the coastal environment and to
maintain biodiversity.
7.
New
development that may be at risk from future sea level rise and storm surge
events will not be protected by the expenditure of public funds.
8.
Ensure
that climate change should not be a barrier to investment in minor coastal
public infrastructure provided the design-life is within the timeframe of
potential impact.
9.
Ensure
planning and management frameworks are prepared for changes in local conditions
as a result of climate change and can respond quickly to the best available
current and emerging science.
10.
Ensure
all plans prepared under the Coastal Management Act 1995 and strategies
relating to the coast, including Coastal Action Plans and management plans
consider the most recent scientific information on the impacts of climate
change.

4.53
Concerns were raised about the New South Wales draft sea level rise
policy statement.[63] The policy states that
‘[t]here is no regulatory or statutory requirement for development to comply
with this benchmark. The benchmark’s primary purpose is to provide guidance to
support consistent consideration of sea level rise impacts, within applicable
decision-making frameworks’.[64] Some inquiry
participants were concerned that the policy was not a mandatory (statutory)
requirement. As Mr Smith from ANEDO commented:
I do not think that this document goes too far to solving the
problems that councils and decision makers face ... To draw all those things
together, this explicitly says, ‘We’re not mandating this. You don’t have to
take it into account. It is just the guidelines.’ It does not seem like a huge
advance to us in terms of dealing with the uncertainty that people are facing.[65]
4.54
There were also concerns about the policy’s statements on liability:
Where assistance is provided to reduce the impacts of coastal
hazards, the Government does not assume any responsibility for these hazards
...
Coastal hazards and flooding are natural processes and the
Government considers that the risks to properties from these processes
appropriately rest with the property owners, whether they be public or private.
This will continue where these risks are increased by sea level rise. Under
both statute and common law, the Government does not have nor does it accept
specific future obligations to reduce the impacts of coastal hazards and
flooding caused by sea level rise on private property.[66]
4.55
As Professor McDonald commented, the policy ‘makes clear that the
government asserts where responsibility will lie ... That is very different
from making clear where liability will lie ... It is only a policy statement.
Until they legislate to eliminate liability, that is still a point that is
easily arguable in court in an appropriate case’.[67]
4.56
This issue opens up broader concerns relating to climate change and coastal
legal issues.
National building standards
4.57
The Department of Climate Change submission notes that the Australian
Government has provided funding to the Australian Building Codes Board to
review and, as appropriate, revise the Building Code of Australia (BCA) to
ensure that the risks of future climate change are recognised in building
practices and possible climate change adaptation measures are considered.[68]
The Australian Building Codes Board develops and implements national standards
for new buildings relating to health, safety, amenity and sustainability. The
funding will be used to outline the major risks from climate change on
Australia’s building stock, investigate where nationally consistent or
state-specific responses are required and identify areas for further research.
4.58
A number of inquiry participants raised concerns about the BCA:
there is a need for the introduction of new controls through
the Building Code of Australia to ensure that buildings are designed and built
to the standard necessary to withstand high wind and water damage.[69]
The Building Code of Australia ... sets the importance of
structure and says that you will design that for a certain probability of, say,
a one in 500-year return period; or an annual probability of one in 500 for the
wind loading on that. What I believe the building code should do, and is doing,
is to require that those probabilities should take into account future climate
change impacts on wind speeds in tropical cyclone areas and on wind speeds in
southern areas. It should also be concerned about the consequences—that is, the
loading from the same wind speeds should be used. But you also should require
that the building standards by which any building is constructed are going to
be sufficiently robust ... to withstand extreme events above and beyond what
might be regarded as currently the values. We need to be able to assess the
capacity of structures.[70]
this is another area where the Commonwealth should play a
role in looking to the building codes to decide what level of resilience is
cost effective to include in the minimum requirements of the building code. I
am currently involving in working with the Commonwealth agencies on a national
energy efficiency strategy, so time has come for a big upgrade in our building
codes for commercial and residential buildings on energy efficiency. The case
for that is overwhelming ... It is an area where we know we are heading for trouble
in terms of more exposure to extreme weather events and we will need to upgrade
our building standards. The Insurance Council does meet with us occasionally
and their constant request is that we do this. Their argument is that if we do
not have higher minimum standards then insurance will become unaffordable for
communities because damage will be so frequent and expensive. That is a bad
situation for Australia to be in if you cannot afford insurance because you
will then get the call on taxpayers to bail people out and you do not get people
managing their own risks. That is definitely an area where some further
Commonwealth assistance would be useful. There is no point in each state
individually researching these matters because they do not change from one side
of the boundary to the other.[71]
4.59
The ICA recommended that the BCA be expanded to ‘incorporate property
protection as a fundamental basis for consideration in building design and
construction’. Currently, the BCA focuses on safety of life as the only
fundamental requirement. The ICA also recommended implementation of ‘a
southerly expansion of cyclone and wind storm related building codes to counter
the predicted southerly exposure of severe cyclones’.[72]
Local government coastal adaptation policies
4.60
While planning and development are governed by statutory frameworks
established at state government level, local governments in all Australian
jurisdictions have responsibility for preparing a range of legally binding
statutory planning instruments such as planning schemes, codes and regulations.
4.61
Individual local council planning schemes generally place an obligation
on councils to consider certain matters when dealing with applications for
planning consent. This obligation provides an opportunity for councils to
incorporate actions that may serve as a mechanism for local community
adaptation to climate change.
4.62
Many local councils have responsibility for determining coastal
adaptation practices for their local government area relating to so-called protect,
redesign, rebuild, elevate, relocate and retreat policies.
4.63
This area proved to be a contentious one, with inquiry participants
raising concerns relating to inconsistencies between different councils in the
adaptation approaches adopted, lack of clarity about liability, and uncertainty
about the effectiveness of the various approaches adopted and the circumstances
under which they should be employed. As Professor McDonald commented:
When is planned retreat going to be appropriate or even
feasible in some areas? In what circumstances should we regard hard engineering
structures as actually preferable to planning and other approaches? How should
planned retreat be implemented? There is an enormous range of approaches to
that question. Who pays for hard structures, so the issues of costing when
benefits flow to particular property owners. And then the question of how
public amenity value should be valued as against infrastructure and private
property values in making all of those decisions.[73]
4.64
Similarly, Ms Mears, Chair of the Victorian Coastal Council, commented
that:
We have to have a framework for managing risk, which is not
something we have at the moment. It is something that we need to work towards.
It will include our adaptation to risk. What are the levels of risk for some
areas? Can they be protected and managed or is it a retreat over time? This is
really an important policy space that we are yet to fully develop. We are at
the beginning of understanding the areas that are vulnerable. We need to
understand within those areas what the assets are that are going to be at risk,
what our response is and then who shares the role in managing those risks.[74]
4.65
A further issue here is what guidance on this matter is provided to
local councils by state governments to ensure consistency in approach and to
what extent local circumstances should determine the approach adopted. Byron
Shire Council has a long established policy of planned retreat for certain
beach compartments within the shire. However, the council noted its
difficulties in implementing aspects of this policy due to ‘a lack of statutory
support, at times’ and recommended that:
Councils need statutory support from the state and federal
governments for strategic planning policies of planned retreat and other
climate change adaptation measures.[75]
4.66
The Victorian Government highlighted the significant future costs
potentially associated with this area in terms of moving entire settlements and
protecting major assets, flagging a possible role for the Australian Government
in ‘providing financial support and policy and engineering options for dealing
with major “retreat” and “protect” options on the coast’.[76]
Similarly, SGS Economics and Planning Pty Ltd commented that:
It is likely to be well beyond the means of local governments
to meet the costs of risk management and reduction measures on their own, and
equally inequitable for coastal councils to bear the costs of changes brought
on by global changes. Councils may even require assistance to meet the costs of
adapting their own infrastructure. Assistance from the State and Australian
Governments will be required.[77]
4.67
Professor Thom also noted that:
We will reach ‘tipping points’ in each and every coastal
community around our coast as sea level continues to rise. Each tipping point
needs to be assessed in relation to the nation’s capacity to pay. When will
barrages be needed at Port Philip or Botany Bay? When will the very low third
runway at Sydney Airport need to be elevated? When will houses around Swansea
need to be relocated as here a 1m sea level rise will inundate 100% of
properties adjoining Lake Macquarie? And when will levees, pumps and seawalls
be demanded by property owners at risk of inundation or erosion?[78]
4.68
Other adaptation options proposed included providing development
approval ‘on the basis of a finite timeframe’[79] and defining ‘coastal
climate change buffer zones to keep development out of lands mapped as being at
risk of inundation’.[80] Wellington Shire Council
described the possible use of covenants on property titles, with owners
acknowledging that they will abide by actions stipulated in an approved climate
change response plan:
Before the development starts, the owner of the land shall
enter into an agreement with the Responsible Authority in accordance with
Section 173 of the Planning and Environment Act, 1987 which will covenant that
the owners acknowledge they will abide by actions stipulated in the approved
climate change management plan.
The agreement will bind the applicant as the owner and shall
run with the land so that all successors in title are bound by the agreement.
This agreement will be prepared at the applicant’s cost and to the satisfaction
of the Responsible Authority, and shall be registered on the title in
accordance with Section 181 of the Planning and Environment Act, 1987.[81]
4.69
A further important point to note here is that adaptation strategies are
already being implemented to address the impacts of coastal erosion. As
Professor Woodroffe highlighted, much could be learnt from past management
practices in this area:
Over the past several decades the sea has risen a few
centimetres along much of the coast of east Australia. Coastal management
programs have not been designed to counter that rise, but in many cases have
accommodated it without noticing. The impacts of large storms and the gradual
recovery following those storms have been far more apparent. Much could usefully
be learned from the behaviour of shorelines over this period. For example, the
widespread introduction of dune management, incorporating dune fencing, dune
access through walkways, exclusion of four-wheel drives, and revegetation would
appear to have reduced and in places reversed retreat that might have been
anticipated as a result of the gradual rise of mean sea level. These management
procedures offer a good basis that could be expanded with further research as
adaptive measures in the face of future sea-level rise.[82]

Conclusion
4.70
Subsequent chapters will revisit the issue of coastal planning. However,
in terms of coastal planning and climate change, the Committee concludes that there
is a need for:
n further work on
ensuring a greater degree of consistency between jurisdictions in how they deal
with issues facing climate change and planning in the coastal zone
n further work on resolving
issues relating to the establishment of a sea level rise benchmark and planning
framework
n further work on
revising the BCA
n further investigation
of liability issues with regard to coastal planning and climate change
4.71
The Committee commends the work of ACE CRC on sea level rise, risk
management and coastal planning, including its national workshop program for
policymakers, planners and engineers.
4.72
The Committee notes that the Local Government and Planning Ministers
Council (LGPMC), which reports to COAG, is currently looking at state climate
change planning policies. In May 2009, jurisdictions
undertook to ‘develop state-specific climate change planning policies to inform
local governments and regional planning responses to climate change by mid
2011’. They further agreed to collaborate with the Climate Change and Water
Working Group, Australian Transport Council and Ministerial Council on Police
and Emergency Management to ‘develop a national framework and tools for use by
local government to inform planning for climate change mitigation and climate
change adaptation’. There was also reference to ‘Queensland work on
establishing leading practice national planning system principles’.[83]
4.73
The NSW Government noted that COAG is
currently:
reviewing inter-jurisdictional arrangements relating to
building, infrastructure and settlements through Working Groups on: Climate
Change and Water; Infrastructure; Business Regulation and Competition (which
considers planning and building reform): and Housing. It is envisaged that this
work will address potential duplication and gaps in effective planning for
coastal communities.[84]
4.74
Against that background, it is also important to note that the issues
‘in relation to coastal settlement and climate change cannot be resolved by
looking at the coastline in isolation to the broader challenge of a sustainable
settlements strategy for managing urban growth in Australia’.[85]
A strategic approach to settlement planning in the context of climate change is
a major national issue. The Committee also draws the attention of all state
governments and local government authorities to the scientific evidence about
sea level rise outlined in Chapter 2.
Recommendation 20 |
|
The Committee notes the Council of Australian Governments
initiative (through the Local Government and Planning Ministers Council) to
develop state-specific climate change planning
policies by mid 2011, to inform local governments and regional planning
responses to climate change. The Committee recommends that the Australian
Government ensure that the outcomes of this initiative are included as
part of the action plan under the proposed new Intergovernmental Agreement on
the Coastal Zone.
|
Recommendation 21 |
|
The Committee recommends that the Australian Government
consider the benefits of adopting a nationally consistent sea level rise
planning benchmark and, if so, whether this be done on a statutory basis or
otherwise. The outcomes of this consideration should then be included as part
of the action plan for the proposed Intergovernmental Agreement on the
Coastal Zone. |
Recommendation 21 |
|
The Committee recommends that the Building Code of Australia,
including cyclone building codes, be revised with the objective of increasing
resilience to climate change. |
Climate change and coastal legal issues
4.78
Climate change law is a new legal discipline and, as commentators have
observed, ‘devising legal solutions to climate change is likely to involve
profound changes to existing governance and regulatory frameworks, with
reverberations felt in many other areas of law such as constitutional law,
administrative law and property law’.[86]
4.79
Uncertainties about legal matters relating to climate change and the
coastal zone was one of the issues most frequently raised in evidence and
documents provided to the Committee. As Mr Stokes, Executive Director of the
National Sea Change Taskforce, commented, ‘[i]n many respects, councils are at
a loss as to how to respond at the moment. What we are seeing is developments
being approved right now that, if some of the projections coming out of the
IPCC are proved correct, will be placed at risk in the future ... there are
still properties being approved today which perhaps it would be prudent not
to’.[87]
4.80
Key concerns raised by inquiry participants included:
n clarity about roles
and ‘who might be liable for what’
At present there is a high degree of uncertainty in relation
to current and future climate change liability. If left unaddressed this
uncertainty will continue to have a significant impact on decision making
processes and information disclosure in relation to climate change hazards.[88]
The state’s view [NSW] is that the risk to a property from
sea level rise lies with the property owner, public or private, so whoever owns
the land takes the risk. Whether it is the state or a private landowner, they
gain the benefit of proximity to the ocean and they bear the risk of proximity
to the ocean.[89]
n consistency of
information, extent of risk disclosure to the public and ‘who knew what, when’
There is ... debate about advising the public of climate
change implications/risks ... with potential property de-valuing concerns
versus people’s right to know. It is necessary to have a clear policy direction
on this from upper tiers of government so Councils have support and clear
direction, without having to go through the courts to see where responsibility
lies.[90]
n coastal planning
policies taking into account the latest information on climate change and
coastal hazards
It is a question of working with some degree of certainty.
That is an issue. What we find at the moment is that an increasing number of
local councils are making planning decisions in a state of great uncertainty
about, say, the future impact of climate change and also in terms of a lack of
clearly defined coastal policy either by the state or anyone else ... They are
making decisions today based on information currently available to them that is
not necessarily up to date.[91]
The liability issues that could be looming for decision
makers agreeing to coastal canal estates today may be something that those
decision makers might want to think about very carefully before agreeing to
those proposals in future.[92]
n clarification about liability
issues with regard to government authorities acting or not acting in terms of
climate change adaptation and possible coastal hazards
I suppose the legal situation that local councils are in at
the moment is that if they get a development application for an area of land
they believe could be vulnerable in the future to sea level rise they are
damned if they do and they are damned if they do not in terms of approving that
development. If they approve it there could be a liability down the track if it
becomes affected and inundated by the rising sea levels and the attendant
severe weather events. If they do not approve it they are going to wind up
before an appeals tribunal.[93]
n clarification about
liability issues with regard to private property holders acting to protect
their properties from the impacts of climate change and about who should bear
the cost of adaptive strategies
soft engineering approaches [eg sand replenishment] ... will
become increasingly expensive, and they raise issues about the extent to which
public money should be spent to protect a few landholdings that occupy prime,
though vulnerable, seafront.[94]
n legacy issues
relating to past planning decisions that had allowed development in low-lying
areas
we have essentially the very big question of the legacy risks
that we are inheriting and our children will inherit. That is a very big
question. We are not going to solve that one overnight, so I think the first
thing we need to do is understand, in a sound, evidenced based way, the nature
of the risk that is arising from past decisions ... We will be presented with
some big challenges. We need to make the right decisions, based on sound
information. Beyond information, the question is: what practical steps do we
take? That is a discussion which has barely begun at this point.[95]
Where we do have issues is twofold. The first is in the
legacy of the past where councils over the years have approved developments in
what will clearly be unsuitable locations into the future. That is a problem.
The other area which is a big problem is the historic zonings, where over the
years we have zoned land that is not yet developed in inappropriate coastal
situations.[96]
n the legal basis
underpinning strategies of protect, adapt and retreat and the permissible scope
of adaptation strategies
if people are going to defend their property then the impacts
of that defending of property may be transmitted to adjacent areas and cause
other potentially detrimental effects in some cases.[97]
n compensation issues
it is a difficult issue to deal with the results of poor
decisions from the past in terms of that vexed issue about compensation—who
pays, who carries the risk?[98]
If current Climate Change predictions are realised
significant numbers of properties will be adversely affected, many so much so
as to become uninhabitable. In those circumstances it is inevitable that some
property owners will look for compensation in return for any strategic actions
any level of government may take to alleviate climate change risks. It is
critical that planning for the financial implications of climate change, in
terms of property compensation, commence without delay.[99]
n the lack of specific
legislation in the area
at the moment, there are a lot of guidance notes and there is
a lot of jurisdictional buck-passing.[100]
A climate change development control which is not
discretionary for local governments to enforce may be the answer.[101]
n right of public
access to beaches
Titles to land in Australia either have fixed ‘right-line’
property boundaries or boundaries based on some natural (usually water)
feature. Right line property boundaries do not change even if the beach recedes
into those properties. That is, in areas affected by coastal erosion, changing
estuary mouth positions or sea level rise, the beach can end up on private
properties. It is critical that the government have the ability to be able to
amend property boundaries, or exercise powers of acquisition, in the event that
erosion intrudes significantly into those private properties and the beach becomes
privately owned.[102]
n indemnity issues
Indemnify local government for advice given in good faith
regarding all natural hazards including those that may be caused or exacerbated
by climate change including, but not necessarily limited to, landslide, bushfire,
coastal erosion, coastal recession, flood and coastal inundation.[103]
the issue for us as a community and as a local government is
that we should not go into defensive management mode and rely on some sort of
statutory immunity and hide behind that in providing information across the
counter. We need to educate our community and make them understand that this is
a shared responsibility.[104]
n potential liability
under the common law of negligence and nuisance
4.81
Several general principles emerge from the discussion above, pointing to
some possible ways forward. These include:
n preventing future
harm
n improving the
statutory framework
n considering broader
indemnification for local authorities
n ensuring national
consistency of information and mandatory risk information disclosure
4.82
In the discussion below, the Committee has often drawn on the evidence
of Professor Jan McDonald. (Professor McDonald has published several
significant legal studies in this area.[105] Her positions include
Director of the Climate Change Response Program at Griffith University and Research
Manager at the National Climate Change Adaptation and Research Facility.) However,
as outlined below, Professor McDonald’s comments were broadly supported by a
number of inquiry participants.
Preventing future harm
4.83
Several inquiry participants emphasised that the focus for coastal
policymakers in taking into account climate change impacts should be on
preventing future harm:
any interventions or regimes that are considered need to
focus principally on approaches that prevent future harm rather than impose
liability for it or establish principles of liability. That relates to
preventing both maladaptive new development and harm where existing development
has already occurred. The fact that a development is in place or infrastructure
is in place does not automatically mean that there will necessarily be harm
ensuing. Those approaches that are aimed at prevention I think need to
recognise that there will always be a level of irreducible uncertainty ... We
need to make sure that any response that is taken now to anticipate and prevent
future harm is itself iterative, flexible and adaptive to build in upfront the
triggers for a ramping up of increased protective measures when a certain event
occurs—when the sea rises to a certain level, for example ... Our approach to
dealing with climate impacts in the coastal zone should be based on trying to
minimise adverse impacts on property, amenity and human health. It should not
be based on protecting ourselves from potential legal liability.[106]
ANEDO submits that one of the principles that should
primarily be considered in all future coastal planning is ‘First, do no more
harm’. It is important to not compound the significant problems already faced
by coastal communities by making further ill-considered planning and
infrastructure which ignore looming biophysical realities. If decisions are
made ignoring this principle, they will inevitably create even larger costs for
future generations to bear, and undermine the concept of intergenerational
equity which should inform true ecological sustainable development.[107]
4.84
The further point was made that these preventative measures should
transfer the costs of adaptation to those who derive gain benefit from the
development, with an emphasis on developers:
Those preventive measures also need to transfer or impose the
costs of adaptation on those principally who derive benefit from the adaptation
or the development in the first place or who are in the best position to pay for
it. It has certainly been my observation over the last couple of years that the
conversation has been around property owners on the one hand and government on
the other hand, whether it is local, state or federal governments. The missing
link in that is the role of the development industry and the incredible
pressures that it places on local governments to approve developments on
marginal lands without taking responsibility for any of the costs that may flow
intergenerationally arising out of future impacts ...
My view is that the property developers will be the ones who
derive the profit from the enterprise and therefore should be the ones who bear
that risk for at least a reasonable time.[108]
4.85
In terms of how this mechanism might work, Professor McDonald commented
that developers could be required to ‘indemnify property owners for 10 years
following the release of the land’. Alternatively, a ‘performance bond’ could
be lodged that ‘endures for 20 years’ or the developer is required to insure
the property—‘if the developer cannot get insurance for a particular piece of
land, that is a pretty good communication of risk to the market’.[109]
4.86
It was also noted that preventative approaches might usefully involve
time-bound approvals:
The fact that we might take a preventative approach does not
mean to say that all development will be constrained in vulnerable areas. Again
I think the planning regime needs to rethink what it means to grant development
approval in a certain area. It may be that we start considering time-bound
approvals more in the nature of leasehold arrangements where an approval is
granted for a development with a 40-year lifespan and then all bets are off
until we rethink or reassess the nature of observations at that point to see
whether the projections have actually materialised.[110]
Improving the statutory framework
4.87
A number of inquiry participants highlighted the need for an improved
legislative framework to clarify liability in respect of past and current
coastal planning decisions and set out what is considered reasonable for
various parties to have known at a certain time:
Local Government requires the legislative power to take
climate change impacts into account when assessing development applications, as
the risk of future litigation is real.[111]
we do need to have some kind of overarching framework that
addresses liability or the scope for liability in respect of past decisions. It
is critical that that be addressed using some form of legislative response
rather than leaving it to the courts. I think it is going to be an extremely
corrosive and stagnating influence on proactive decision making if we stay in
this state of paralysis where local governments, and even to some extent state
governments, are worried about the risks of exposure to liability ... A
liability regime needs to, at the very least, specify what is reasonable for
both potential plaintiffs and potential defendants to have known at a certain
time. I think that is an absolute minimum.[112]
4.88
Professor McDonald pointed to the complexity of this issue, including
that past coastal adaptation works undertaken by different parties may create
additional problems or create expectations for other parties that these works
will also be undertaken for them:
a lot of issues will arise in respect of protective
structures that are already in place that will prove to have been inadequate,
poorly constructed or poorly maintained or that are not located in the
locations that they now need to be located in but which have created an
expectation for neighbouring communities that they will get the same sort of
protective structure. It is not just a case of having approved developments
that put certain residents or property in harm’s way. It is actually
governments, whether departments of infrastructure or local governments, who
have undertaken works that may create additional problems, exacerbate climate
change related coastal hazards or create an expectation for other parties that
those works will be done for them as well.[113]
4.89
It was further noted that, if there is going to be ‘a liability regime
imposed legislatively outside of the courts, there probably does need to be a
fairly comprehensive articulation that transfers the risks and the liability
back onto the individual property owner’.[114]
Broader indemnification for local authorities?
4.90
Several inquiry participants commented on the benefits of broader
indemnification of local authorities:
Federal and/or State statutory exemptions against ‘climate
change’ litigation are imperative to the protection of public funds.[115]
there will probably need to be a far broader indemnification
of local authorities, simply to manage the risk of liability in the future.[116]
4.91
Public authorities can be exposed to liability through both their
statutory responsibilities and the requirement under common law to act with due
regard to the rights of others. The forms of common law liability that public
authorities are most commonly exposed to are claims in nuisance[117]
or negligence.[118] However, under civil
liability legislation in each state, public authorities (state governments,
local councils and other government instrumentalities) are exempt from
liability where it can be established that they have acted reasonably—that is,
they are only liable if their actions or inactions are ‘so unreasonable’ that no
other authority would consider them to be reasonable. An essential ingredient
of any developing test of what is a reasonable response ‘must include a genuine
attempt by local government officers to stay informed of current research
applicable in their jurisdiction and of changes to relevant policies and
regulations’.[119]
4.92
Civil liability legislation also exempts public authorities from
liability for ‘obvious risks’. Obvious risks are those that, in relevant
circumstances, would have been obvious to a reasonable person, including risks
that are a matter of common knowledge. For example:
With the potential effects of climate change now widely
known, there is a strong argument that a reasonable person who lives on the
coast should be aware of the dangers posed, and therefore that damage from
erosion and sea-level rise would be damage from an obvious risk ... Therefore,
it would be difficult for a landholder to bring a negligence action against a
local council for approving a development application in 2007 in a coastal area
subject to erosion, since a reasonable landholder would have been well aware of
the risks when submitting the application. No liability would arise in such a
circumstance.[120]
4.93
Local governments and other authorities are therefore only at risk of
civil liability for failing to account for the impacts of climate change if
their actions or inactions constitute a wholly unreasonable response to the
risk of climate change. Accordingly, civil liability legislation offers a
degree of comfort and security for local government—noting, however, that
judicial interpretation of civil liability legislation may vary and benchmarks
may shift in defining what is manifestly unreasonable.[121]
4.94
A further key issue here is the need for local government to ensure they
are informed about climate change information particular to their specific
local government area:
While much of the scientific evidence about climate change
impacts is highly generalised, it is without doubt that more specific and
localised information will soon become available. It is questionable whether
the defence of compliance with general procedures in s 42 of the Civil
Liability Act 2002 (NSW) and its equivalents in other states will be a
reliable one if local governments’ general procedures and applicable standards
fail to take into account regionally applicable, authoritative predictions
about climate change impacts as and when they become available. The duty on
local government officers here, as in all other areas, is to ensure their state
of knowledge and awareness remains at a level that it is reasonable to expect
for a local government of such size and resources.[122]
4.95
New South Wales provides further protection from liability through its Local
Government Act 1979. New South Wales is the only state that provides
statutory protection for local government in this way. Section 733 of the act
exempts councils from liability ‘in respect of advice furnished, action taken,
or anything done or omitted to be done which relates to natural hazards in
the coastal zone, provided that the decision was taken in good faith’.[123]
‘Good faith’ is assumed if the council acts in accordance with the NSW
Coastline Management Manual 1990, which in turn means councils must ensure that
the potential effects of climate change are considered when conducting their
activities. Professor McDonald commented that this is a provision ‘that other
states should consider adopting’.[124]
National consistency of information and mandatory risk information
disclosure
4.96
Much of the evidence to the inquiry emphasised the need for
national consistency in information provided to the public about climate change
risks. For example, Professor McDonald pointed to the need for:
consistency in the kind of information that has to be made
available to property owners and prospective purchasers, the way in which that
information is presented and over what timescales it is interpreted as being
relevant and the form in which it is available. At the moment some of it is
available on a certificate of title, in other circumstances you have to go and
find it for yourself on the web. I think there is an important role for
national consistency in what we expect every prospective purchaser will automatically
be informed of when they are considering the purchase of property. A national
approach to that is the only way in which you are going to be able to avoid the
concerns about everyone’s property value being affected. At the moment it is
whoever blinks first, it is almost a game of chicken, because no-one is really
willing to provide all that information in a way that will lay out in full,
vivid detail the implications for certain locations ... consistency of
information is a critical requirement across the country .[125]
4.97
Similarly, the ICA proposed implementation of ‘legislation harmonised
across all states requiring mandatory disclosure of all known and predicted
risk data by state and local governments to property purchasers during property
conveyance and title search processes’.[126]
4.98
The Committee notes the serious issues raised here, concerning
consistent and comprehensive disclosure of climate change risks and coastal
hazards. As Professor McDonald further commented:
I do not think it is satisfactory that at the moment a
prospective purchaser has to go online and hope that their prospective local
authority has flood maps that are online and then has to try and find out
whether those flood maps take into account projected sea level rise and, if so,
what level of sea level rise. It really does confer a very heavy burden on
purchasers. Whilst some may be well equipped to do that, I suspect that a lot
of people are not. It is a situation where at the moment we probably have an
imperfect market, to use economics terminology, because people are not making
fully informed decisions. People may still not make fully informed decisions,
but they might be a little better informed.[127]
Recent cases relating to climate change impacts on the coast
4.99
At the time of the inquiry, a number of legal cases concerning climate
change and coastal planning had been decided through the courts. Many of these
cases turned on the question of whether the decision maker had considered the
potential impacts of climate change on proposed developments in vulnerable
coastal areas. As the cases discussed below suggest, there is an emerging trend
to consider climate change risks within the broader ambit of the concept of
ecologically sustainable development (ESD). Many statutes require promotion of
or regard to the principles of ESD. The principles of ESD most relevant to
climate change impacts are the precautionary principle and the principle of
intergenerational equity.
4.100
Reliance on ESD concepts to require a consideration of future climate
change impacts was a feature of a decision issued by the Victorian Civil and
Administrative Tribunal (VCAT) in Gippsland Coastal Board v South Gippsland
Shire Council & Ors.[128] This is a significant
case in that climate change factors were established as grounds to block a
coastal development. Figure 4.4 provides a summary of this case.
4.101
Figure 4.4 also provides a brief summary of other recent cases in this
area. These cases suggest that climate change considerations are increasingly
likely to be seen as relevant, if not essential, to local government
environmental assessment processes and the need for consent authorities to
consider the impacts of climate change on coastal developments through their
consideration of ESD: ‘the only sensible strategy for local governments is to
start incorporating climate change considerations into a wide range of their
decisions and activities’.[129]
Figure 4.4 Recent cases relating to climate change impacts
on coastal developments[130]
Gippsland Coastal Board v South
Gippsland Shire Council & Ors [2008] VCAT 1545
‘VCAT
refused consent for residential developments in a low-lying coastal region. The
local council had previously approved permits for six residential developments
in the Grip Road area of Toora, an area zoned for agricultural and mixed land
uses. The Tribunal’s refusal was primarily based on inconsistency with zoning
and planning controls. Importantly, however, VCAT also applied precautionary
ESD principles to find that development consent should not be granted in view
of the “reasonably foreseeable risk of inundation” to the land and proposed
dwellings due to sea level rise induced by climate change. This was despite the
absence of specific provisions in the Victorian planning legislation requiring
consideration of sea level risk. The Tribunal stated:
“We
accept that there is growing evidence of sea level rises and risks of coastal inundation.
While we acknowledge that there is uncertainty as to the magnitude of the sea
level rise, it is evident that the consequences of such rises in level will be
complex due to the dynamic nature of the coastal environment. Put plainly,
rising sea levels are to be expected. The range of impacts may well be beyond
the predictive capability of current assessment techniques. In the face of such
evidence, a course of action is warranted to prevent irreversible or severe
harm”’.[131]
Walker v Minister for Planning (2007) NSWLEC
741
‘Justice
Biscoe found that the Minister for Planning had failed to consider ESD by
failing to consider whether the impacts of the proposed development would be
compounded by climate change. In particular, the Minister failed to consider
whether potential flooding associated with climate change may impact the land
at Sandon Point, which is located on flood prone land ... The Court has made it
clear that consent authorities will be required to demonstrate that real regard
was had to principles of ESD and to climate change impacts. As a result of this
decision, councils should assume that there is the potential for greater
flooding and inundation as a result of climate change in the coastal zone when
considering coastal developments and take this into consideration. Councils
must be able to demonstrate that they have taken into account the potential
impacts that sea level rise and climate change on the proposed development and
whether any mitigation measures could be put in place to lessen any future
flooding impacts.’[132]
Northcape Properties Pty Ltd v
District Council of Yorke Peninsula [2008] SASC 57
In
this case, ‘the Yorke Peninsula District Council had taken a proactive approach
to the likelihood of sea level rise caused by climate change. Its decision to
refuse an application for residential development on the outskirts of Marion
Bay was appealed by the developer. Council’s decision to refuse the application
was upheld in the Environment Court of South Australia and, on appeal, in the
Supreme Court. Both decisions
relied
on expert evidence that coastal erosion of 30-45 m could be expected in the
next 100 years, taking sea level rise into account. Both decisions confirmed
and endorsed the council’s objectives for coastal development, stated in the
applicable Development Plan. These gave consideration to sea level rise from
climate change in the following terms:
“To
promote development which recognises and allows for hazards to coastal
development such as inundation by storm tides or combined storm tides and
stormwater, coastal erosion and sand drift; including an allowance for changes
in sea level due to natural subsidence and predicted climate change during the
first 100 years of the development”’.[133]
Existing coastal development and concerns of individual property holders
4.102
As legal commentators have noted, ‘courts at this stage are only
considering climate change impacts in the context of new developments and have
not yet starting considering the complex issues associated with the impacts of
climate change on existing developments’.[134] For example, the
Sunshine Coast Environment Council pointed to existing development on
flood-prone coastal floodplains adjacent to rivers and estuaries as being ‘a
recipe for litigation into the future’.[135]
4.103
Professor McDonald commented that:
something needs to be done to assist those people if in fact
their properties are no longer habitable because of the frequency with which
they are flooded or affected or because erosion has rendered them precarious.
It does no good at all to say, ‘Well, you should have thought about that and
done something about it’ if the alternative is that they are homeless. One way
or another, some solution needs to be found to assist individuals in those
circumstances.[136]
4.104
The complexity of these issues was made very clear in evidence to the
Committee from a resident from Old Bar on the New South Wales Central Coast.
This particular case raises issues about liability and existing developments
(in this instance, housing having recently been demolished) and alleged
existing approvals for new developments.
4.105
By way of summary, the individual’s home had to be demolished because of
coastal erosion. They were then informed that they would have to wait for two
years, for a council study to be completed, for confirmation on whether consent
to rebuild, further back on their property, would or would not be
granted—noting that the individual understood that consent to rebuild had
already been given before their home was demolished. For the individual, this
raised a series of issues relating to state and council coastal land use
planning policies, accountability of officials, land values, insurance, home
mortgages, compensation and liability—see Figure 4.5.
4.106
The future loss of people’s homes to the sea as a result of coastal
erosion and inundation was a major issue raised with the Committee. Concerns,
for example, were raised about coastal properties in parts of NSW—at Narrabeen,
along Belongil spit at Byron Bay and on the Central Coast:
At Norah Head coastal erosion has forced the local council to
issue orders to residents to dismantle structures from the backyards of
properties to reduce pressure on the seaward slope to assist in prevention of
major land slippage. Heavy rain plus wave energy impact on the toe of this
slope has placed a number of homes in the unenviable position of currently
having no backyards plus the potential of losing their homes to the sea. Wyong
Shire Council and the State Government have both committed extensive amounts of
monies to try and minimise the rate of erosion of this slope. The reality is
that these works may not prevent a loss of these properties if a severe storm
were to impact onto this part of the Dobell coast line.[137]
locations like the Belongil in Byron and Collaroy-Narrabeen
... have development that is absolutely on the beach frontage where you are
going to have a significant hazard impact from sea level rise.[138]
Figure 4.5 Excerpt of evidence from a coastal resident
from Old Bar, NSW
My
concerns are not just for myself but for all coastal residents who may face
this in the future. If how our situation has been handled so far is to be a
benchmark, basically it is embarrassing ... The failure to accept any sort of
responsibility is just not acceptable for those involved ...
In
2001 we purchased our properties. There were no signs of any erosion. In 2002
minor erosion started. In 2003 we took the view that it was going to become an
issue on our place. We applied for subdivision on our property ... On 14 June
last year we had the highest tide in 22 years at Old Bar. ... It took close on
six metres of lawn in four hours ... Two weeks after that I was served notice
by the council to demolish which I abided by. I demolished my homes believing
that we had a valid consent, that we could rebuild as they have put in writing
to us; that was where our homes were supposed to go ...
I
was told last week by council that that study that they are undertaking is
still around two years away from finalisation, as in rezoning where it goes to.
What do I do for the next two years is my point? I have lost my homes but
council has now said, ‘Well, you have lost your homes. You have put in an
application to rebuild those homes. Even though we have said that is where you
are supposed to build those homes, we are going to defer it’ ...
So
what do I do for two years? Who pays my mortgage? ...
In
our particular case at Old Bar the state government and local council have been
aware of the erosion issues in that particular piece of coastline since the
1940s. They have been quite happy to collect my land taxes ... If you cannot
rebuild, what is it worth, really—nothing ... They have been quite happy to
allow development in the last 50 years ...
All
along I have played by the rules and believed that there was a policy in place.
It is still current. It was implemented by a government department, local and
state, and as soon as something goes wrong I have to hold the ball. Nobody else
wants to know about it ...
How
can no-one be accountable for that? It is just not about us. This is my story
but if this is going to be such a big problem then surely there have to be some
guidelines where everyone is in the same category, where landowners are made
completely aware at time of purchase of whose liability it is going to be; what
responsibility is going to be accepted by government or if it is up to the
landowners themselves because then values on that land obviously apply
accordingly ...
We
contacted both state and federal governments regarding any sort of assistance,
keeping in mind that we have had to pay to demolish our own homes. Because it
was not declared a natural disaster by council, the best that we are told we
are eligible for is welfare payments. Upon contacting welfare the first thing
they do is say, ‘What is the valuation on your house?’ Then it is: bang, no,
you are not entitled to welfare ...
We
are sort of stuck in that time warp for two years until this is resolved. We do
not have two years of mortgage payments left. We just do not know where to
turn. Where do we go?

Keys, Transcript of Evidence, 26 March 2009, pp.61-65
4.107
Mr Attwater from SGS Economics and Planning commented that:
There is a need to allow existing owners to re-evaluate their
choices and to suffer minimal losses from the changing conditions, while
ensuring in the future that coastal property owners factor in the costs
associated with managing developing risk.[139]
4.108
Mr Attwater further proposed that, as existing owners ‘were not aware of
the developing risk and are not in control of the causes of this developing
risk’, for a ‘period of 25 years, the cost of risk reduction and management
measures be borne by the wider community’:
After that time, the cost of further risk management measures
would be the responsibility of those that benefit from coastal use or
occupation. This condition should eventually be applied to all coastal
property titles.[140]
4.109
There was also a proposal that for existing property subject to
increasing risk, ‘triggers be identified that would require an adaptation
response to keep risks at acceptable levels’:
In this way the community will respond to actual changes in
risk as the sea level rises or erosion progresses, not to events forecast for
the distant future. Triggers should be soon enough to plan action and respond
before risk become excessive, not sooner. The action taken should manage the
risk as it develops—it need not all be done immediately.[141]
Conclusion
4.110
The Committee recognises that climate change raises many complex legal
issues with regard to the coastal zone, as reflected in the many concerns
raised by inquiry participants. The Committee also points to the high level of
uncertainty about roles and responsibilities in terms of potential liabilities
in this area.
4.111
Local councils are at the forefront of day-to-day coastal management and
had major concerns in this area. As the evidence provided to the Committee
underlines, councils need to develop clearly defined policies to deal with the
impacts of climate change and make the risks of climate change impacts an
explicit part of their decision-making criteria to assist in limiting their
potential exposure to legal action. As the cases discussed above suggest, consent
authorities also need to consider the impacts of climate change on coastal
developments through their consideration of ESD.
4.112
That said, however, Professor McDonald emphasised that, in her view:
the trend now in the courts is to transfer personal
responsibility back to individuals and, in respect of a prospective purchaser,
for the most part, they probably could make appropriate inquiries now.[142]
4.113
Further, Professor McDonald commented that the ‘circumstances in which
the common law holds governments liable in some circumstances ... will probably
not apply in the future with respect to most coastal climate hazards because,
for the most part, in 2009 prospective purchasers are in a position to protect
themselves by making appropriate investigations’.[143]
4.114
However, concerns remain about liability and existing coastal developments.
Further, there are clearly concerns about legal issues relating to climate
change adaptation and the permissible scope of adaptation strategies at the
local level. The legal challenges of climate change adaptation therefore
require close monitoring and evaluation.
4.115
As discussed, the Australian Government has established the National
Climate Change Adaptation Framework, which is at the early stages of
implementation. However, the Committee is not aware of any specific work having
been undertaken or currently being undertaken by the Australian Government on
legal issues relating to climate change impacts and adaptation, particularly
with regard to the coastal zone.
4.116
The Department of Climate Change confirmed that it had not at this
point:
worked through a specific policy position on liability. I can
say that, in the context of the COAG work, we have flagged the need to develop,
on a national basis, a clear statement of roles and responsibilities between
government and private sectors—whether that be businesses or communities, down
to householders—and within government, between Commonwealth, state and local.
We really do not have that blueprint at this time. So that proposition has been
on the table in the COAG officials’ discussions, and I think it will continue
as an immediate focus for how we move that forward. If there is a public policy
position on roles and responsibilities then that will start to flow through in
terms of liability in the exercise of those responsibilities.[144]
4.117
Given the complex nature of this area, the potentially significant
social and economic costs involved and the significant exposure of coastal regions
to climate change risks, the Committee believes further investigation of this
matter is urgently required. As Professor Stevens from the Australian Academy
of Technological Sciences and Engineering commented:
We realise this is a difficult problem. You can be in legal
problems if you do not do something or if you do something ... The legal side
needs to be examined much more closely than we have in the past ... I would
rather see some research being done now rather than having it all developed by
litigation in the courts.[145]
Recommendation 22 |
|
Noting the gap in research on legal issues and climate
change impacts on the coastal zone, the Committee recommends that the
Australian Government request that the Australian Law Reform Commission
undertake an urgent inquiry into this area, with particular focus on:
n clarification
of liability issues with regard to public authorities acting or not acting in
terms of climate change adaptation and possible coastal hazards (eg legal
basis to implement adaptation strategies of protect, redesign, rebuild,
elevate, relocate and retreat)
n clarification
of liability issues with regard to private property holders acting to protect
their properties from the impacts of climate change
n legal
issues associated with the impacts of climate change on existing
developments, as opposed to planned new developments
n mechanisms
to ensure mandatory risk disclosure to the public about climate change risks
and coastal hazards (eg legislation harmonised across all states requiring
mandatory disclosure of all known and predicted risk data by state and local
governments to property purchasers during property conveyance and title
search processes)
n whether
there should be broader indemnification of local government authorities |
