No. 22 (City of Sydney) Squadron is a Royal Australian Air Force (RAAF) mixed Permanent and Reserve squadron that provides support for the RAAF in the Sydney region. Formed in 1936, the squadron served in Papua New Guinea during the Second World War, and later followed the Pacific War as far as the Philippines. Following the war, the squadron was re-formed in 1948 but was converted to a non-flying support role in mid-1960. It is currently based at RAAF Base Richmond, New South Wales.
