The southern state of Victoria has declared a State of Disaster. This declaration "gives authorities the ability to suspend Acts of Parliament and take possession of properties."

That sounds like carte blanche.

Melbourne residents are currently under curfew.

It's only been instituted once before, 7 months ago by the same premier, Daniel Andrews, during the Victorian 2020 bushfires, which claimed 3 lives in Vic (the worst impact was in NSW).

There's also talk of police being granted powers to demand access to people's phones to check gps tracking and whether they have violated lockdown rules.

Andrews is the only Australian premier to have signed up for a Belt & Road project.
