Electronic Frontiers Australia (EFA) have launched a petition against the Government's mandatory Internet filtering policy, which will eventually be presented to the Senate:

http://www.efa.org.au/2010/01/18/sen...ship-petition/

There's a physical and a electronic petition. You can only sign on one of them.

So get crackin' and sign the petition, and encourage as many other people as you can to do the same.

With both petitions you must sign using your real name and not a nickname (or web username) otherwise the signature will be invalid. If you're signing the electronic petition, you must use a valid email address.
