[1][2] Justice Action's coordinator is Brett Collins,[3][4] an ex-prisoner who began with the organisation in 1979 as co-founder.

Alongside Collins, Justice Action is run by a team of interns who are university students in law and other degrees.

Justice Action provides ongoing support to prisoners and involuntary mental health patients on a case-by-case basis, with an emphasis on cases that deal with issues of abuse, mistreatment or human rights.

Justice Action has mounted recent high-profile campaigns on prison education and access to computers in cells, visitation rights for women prisoners, the prisoners' right to vote,[5] the potential of a prison-based Needle Syringe Program,[6] and the right of involuntary mental health patients to access educational programs, and make decisions concerning their treatment.

[18] Justice Action subsequently challenged the ban, taking the case to the Human Rights and Equal Opportunity Commission (HREOC).
