No, you don't get to blame Australia's insanity on the US. They're fully in control of their own destiny and are one of the richest, most privileged nations in world history. Australia will have nobody else to blame if they plunge further into fascism from here.
In 1997 they banned “defensive” firearms. The guns you want because they work well. Semiautos, center fire handguns, pump shotguns. Bolt actions are still possible to get, but not great at self-defense, or overthrowing your government.
Side note… in 1997 these guns were banned, and crime fell. As it turns out though, not only was crime already going down, but there was an increase of 2x police per capita, and curiously crime in the USA fell at a greater rate with no gun ban or large increase in police, crime was high in the 90s for some reason, some people say lead paint bans but the causation is weak.
Also, you forgot Paul Hogan. And Kylie Minogue. And Nick Cave.
Also, while absolutely nothing sticks in my mind about either, the names of Kevin Rudd and Kim Beazley have been retained in my memory.
If there's places Americans want to go, it's Canada, Europe or Asia, though I think their opinion of Europe is a little overrated if anything.
