That seems very bizarre to me. I'm not sure what you're talking about here exactly, what you've heard/read. Compared to which countries? Where are you, that censorship in Australia seems like a dealbreaker, or a way of feeling so superior? How would 'it' affect you at all? "The fact that the populace is okay with such a policy" - is it a fact, or your guess?
(Personally, the apparent US movie/TV morality of genitals or swearing being forbidden, but someone shooting peoples' heads off by the dozen being absolutely fine, seems crazy to me. The other way around would be far more sensible. At least for childrens' viewing.)
p.s. I just learned more than I ever knew about a history of censorship in Australia by reading https://en.wikipedia.org/wiki/List_of_films_banned_in_Austra...
