Australias law enforcement community have a strong influence on Australian culture, and it is they who are lobbying for more restrictions on Australians' free speech, censorship, and use of cryptography. There isn't really any legislation which protects free speech in Australia, like there are in many other western nations - there is instead an 'implied right' granted to Australian citizens by the sovereign, but this is mostly an untested grey area at the moment - and Australians in general don't care about their basic human rights as long as there are avocados to smash.
