The South Australian Branch has a high level of membership, meets regularly throughout the year, and has an elected committee planning events and activities.

Members have been particularly active in opposing nuclear weapons through ICANi, and by encouraging municipalities to support the abolition of nuclear weapons through Mayors for Peace.  Members have also been part of the successful international campaign to ban landmines. The Branch has strong links with other local peace groups, with members participating regularly in SA peace activities including Palm Sunday and Hiroshima Day celebrations.

There is an active student group, especially at the Flinders Medical School, with students supported by the branch to participate in national and international campaigns. In 2007, SA student members hosted a successful regional meeting for IPPNWi students.
