The government, projecting a comprehensive internet filter, originally assured internet users that they could legally receive banned content by contacting their providers and circumventing such restrictions. Now the government says they can't. All illegal content, which should include everything from pornography to political and religious speech violating Australia's hate laws, will be forbidden. It will be illegal to create or receive communication which the government disapproves.
Actually, according to Colin Jacobs of Electronic Frontiers Australia, the National Internet Filter would have little effect on such illegal internet content as child pornography since it would not cover file-sharing networks. We may conclude that politically incorrect speech would probably bear the brunt of censorship.
