Catallaxy has picked up on the Internet filtering issue and has offered a useful link for those keen to get mobilised on this issue.
From the No Clean Feed website:-
Call the Minister
There’s nothing like a personal phone call to get the message across. Call the minister’s office on (03) 9650 1188 and let them know your objections.
Write to the Minister
A personalised letter to the Minister sends a powerful message: We don’t like the policy, and we care. Letters can be sent to the Ministerial office:
Senator Stephen Conroy
Minister for Broadband, Communications and the Digital Economy
Level 4, 4 Treasury Place
Melbourne Vic 3002
The No Clean Feed website includes other options also such as petitions and the ministers email address. Check it out and start making some noise.
