"While senators change their minds daily, and the media report that the filter will go ahead, or won't go ahead, almost as regularly the fact remains this issue will not be put to bed unless Australians defend their democracy against the very ideology of censorship culture," the DLC press materials said.
"March in March is an upbeat event to give people an opportunity to stand up, be heard and hold the government accountable for their plans of forcing mandatory censorship on a very unwilling public."
The DLC has been organizing rallies in capital cities since December to raise awareness of the government's plans to censor the Internet.
The government's attempt to establish an Internet filter lost a major supporter in Parliament last month.
The rally is planned for 1 p.m., following an 11 a.m. press conference. Plans call for speakers from all sides of the political spectrum with a mix of live entertainment, including bands and DJs, and other special guests.
