Each member of the AIP belongs to a state branch, typically coinciding with their place of residence. Each member may belong to any number of groups.
The AIP's branches and groups are run by AIP members who kindly volunteer their time. Contact information for the AIP's branch and group volunteers can be found on the Committees page, under the tab About the AIP.
Local AIP events and activities are managed by the state branches.
Members of the Australian Institute of Physics can opt to join any number of the formal subgroups, which address specific interests relevant to physics. These groups are formally created by an act of the AIP Council as per page 28 in the AIP Constitution. These groups are useful for networking purposes, and participate in organising the program for the AIP Congress.
