About Us


The Australian Institute of International Affairs (AIIA) is an independent non-partisan, non-profit organisation which promotes the discussion and study of international affairs and issues through frequent lectures, as well as conferences, seminars and overseas study tours.

Established in New South Wales in 1924, and in Victoria in 1925 as branches of London’s Royal Institute of International Affairs (Chatham House), the AIIA was created as an Australian entity in its own right in 1933. Today, as a federated body the AIIA has branches in all states and the ACT.

The AIIA was voted the top Think Tank in Southeast Asia and the Pacific in the Global Go To Think Tanks Index in 2015, 2016, and 2017.

In Victoria, the AIIA is based in Dyason House in East Melbourne, a short stroll from the Melbourne CBD. The house is named after E.C. Dyason, a prominent past member of the Institute and one of its most generous benefactors.

During its long history, AIIA Victoria has involved many notable authorities and leading figures within the international affairs sphere, including Sir John Latham, Sir Owen Dixon, Sir Ian Clunies Ross, Sir Robert Menzies, and Professors Norman Harper and MacMahon Ball.

AIIA Victoria is governed by Council members from a wide variety of backgrounds, all with a keen interest in International Affairs; and is strongly supported by volunteers and interns, and by the generosity of its members.

Among key events in Melbourne are weekly lectures, usually with a focus on major international issues of the moment, the annual Sir Zelman Cowen Oration dinner, and the International Careers Conference for students.

Membership is open to all Australian residents, corporate bodies, diplomatic representatives, schools and students.

Tickets to Institute events are also available to all members of the public.
