GA v Director of Immigration

Indefinite administrative detention of a non-citizen with no real prospect of removal is unlawful as punitive and contrary to Ch III of the Australian Constitution, overruling Al-Kateb v Godwin.

HCA upheld NSW ag-gag laws as valid notwithstanding a burden on the implied freedom of political communication, applying the structured proportionality test.

HCA upheld WA COVID-19 border closure legislation as valid under s.92, finding restrictions on interstate movement were reasonably necessary and proportionate to protect public health.
