The Australian Institute of International Affairs Victoria (AIIAV) is a non-profit think tank based in Melbourne, Australia, and a branch of the national Australian Institute of International Affairs (AIIA). However, it operates independently from the National Office in Canberra and was also founded earlier than it. The AIIAV office is based in Dyason House, named after E.C. Dyason, a prominent past member and one of its most generous benefactors. Membership is open to Australian residents, corporate bodies, diplomatic representatives, schools and students.
