Unsurprising, Australia is one of the most moralistic and nanny state governments there is for a "western democracy" (yes it's southern hemisphere, but just lump them in with the rest of them). They have some of the most restrictive censorship policies in the world. Can't bring in vidya or anime if it's too naughty, can't browse sites if the government doesn't like it. Their own constitution doesn't have explicit freedom of press protections, 3 years ago they raided Aussie news offices to search for info leaks from the government to journalists. They put people in camps over Covid.
Why is it like this? IDK, maybe something imprinted deep within by their criminal ancestors give them a desire to be a prison island.
