The Estonian Archives in Australia (EAA) was established by the Council of Estonian Societies in Australia on 5 January 1952. The EAA is one of the four Estonian Archives existing outside Estonia and holds an important collection of material relating to the lives and achievements of Estonians living outside Estonia.

Since 1994 the Archive has been housed in Estonian House, not far from the centre of Sydney. EAA are funded for their day to day expenses by the Council of Estonian Societies, the parent body for all Estonian Organisations in Australia.

The archive comprise mainly published material, personal papers and memoirs, records of the activities of organisations, photographs, sound recordings, films, artefacts, ephemera and textiles. A major part of the collection consists of more than 10,000 reprints of scholarly works by researchers of Estonian origin living all over the world. This represents the largest collection of such material anywhere in the world.
