Mate, when it comes to aviation in Australia v USA:
Australia was founded as a penal colony, recent events proved that Australia has not moved on from those roots. You won't find a country anywhere else in the world that enjoyed being locked down and treated like the future criminals that we are as much as Australians.
It's pertinent when discussing anything legal in Australia that "everything is illegal unless proven otherwise" including in a court of law. In the USA "everything is legal unless proven otherwise"
In Australia, people are scared of politicians, in USA politicians are afraid of the people.
Bear those in mind and you'll get a picture of aviation life in Australia.
