During the Second World War 9 (Fleet Cooperation) Squadron flew Supermarine Seagull Mk II aircraft from land bases and ships at sea. 9 Squadron had aircraft serve with HMAS Australia at Dakar during the neutralisation of Vichy French forces; HMAS Perth on patrols in the Mediterranean Sea and the Sunda Straits; and HMAS Canberra in support of the US Marines landing at Guadalcanal. The squadron also lost a Seagull aircraft and all crew flying from HMAS Sydney, when the vessel was sunk off the coast of Western Australia in November 1941.

In January 1943 the squadron moved to Bowen in Queensland and performed patrols and reconnaissance. By the end of 1943, with half of Australia's cruisers lost and carrier-borne aircraft taking over the role of the Seagull, 9 Squadron was withdrawn and disbanded on 31 December 1944.
