The Queen

Although the Queen is nominally a constituent part of the Parliament, the Constitution immediately provides that she appoint a Governor-General to be her representative in the Commonwealth.[3] The Queen’s role is little more than titular, as the legislative and executive powers and functions of the Head of State are vested in the Governor-General by virtue of the Constitution.[4] However, while in Australia, the Sovereign has performed duties of the Governor-General in person,[5] and in the event of the Queen being present to open Parliament, references to the Governor-General in the relevant standing orders[6] are read as references to the Queen.[7] The Royal Style and Titles Act provides that the Queen shall be known in Australia and its Territories as:

Elizabeth the Second, by the Grace of God Queen of Australia and Her other Realms and Territories, Head of the Commonwealth.[8]
