Electronic Frontiers Australia Inc. (EFA) is a non-profit Australian national non-government organisation representing Internet users concerned with online liberties and rights.

It also advocates the amendment of laws and regulations in Australia and elsewhere which restrict free speech as well educating the community at large about the social, political, and civil-liberties issues involved in the use of computer-based communications systems.

[6][7] In 1999, the organisation moved against legislation aiming to filter internet pornography and other material deemed unfit for public consumption online that was pursued by politicians such as Brian Harradine.

"[10] One of the reasons mentioned is that suppressing such content results in perception that the speaker must have something important to say, and "massively increased interest in what would otherwise be marginal ideas."

In 2006, the EFA pushed against Cleanfeed, a mandatory ISP level content filtration system proposed by Kim Beazley.
