Australia played a small role in the Italian Campaign. The RAN returned to the Mediterranean between May and November 1943, when eight  were transferred from the British Eastern Fleet to the Mediterranean Fleet to protect the invasion force during the Allied invasion of Sicily. The corvettes also escorted convoys in the western Mediterranean before returning to the Eastern Fleet. No. 239 Wing and four Australian Article XV squadrons also took part in the Sicilian Campaign, flying from bases in Tunisia, Malta, North Africa and Sicily. No. 239 Wing subsequently provided air support for the Allied invasion of Italy in September 1943, and moved to the mainland in the middle of that month. The two Australian fighter bomber squadrons provided close air support to the Allied armies and attacked German supply lines until the end of the war. No. 454 Squadron was also deployed to Italy from August 1944, and hundreds of Australians served in RAF units during the campaign.
