Summary
Amends the Migration Act 1958 to: establish a framework which requires certain visa holders to revalidate certain information, either within a specified period (a routine revalidation check) or if the minister determines that it is in the public interest (a public interest revalidation check); provide that certain events that cause a visa that is in effect to cease will, as a general rule, cause a visa that is held, but not in effect, to be taken to cease; and enable the use of contactless technology to clear travellers through the immigration clearance system (SmartGate).
