Red Fightback contains Caucuses. The purpose of a Caucus is to provide a forum for members that experience a particular form of oppression to: develop the party's positions relating to that Caucus; advise the party on matters relating to that Caucus; and provide political education, support and community for members.

Currently there are four recognised Caucuses:

Anti-Patriarchy Caucus

Racially Oppressed Caucus

Disability Caucus

Past & Present Sex Workers Caucus
