There are several ways you can fight it.
1. Voting. If you live in New South Wales, Queensland, Victoria or Tasmania, you can vote for the Pirate Party in the Senate on Saturday. If you live in NSW, Victoria or Western Australia, you can vote for the Wikileaks Party. Live anywhere, and you can vote for the Sex Party or the Greens.
2. Activism. Join one or more of these parties.
3. Software. Write software that circumvents the censorship.
