The 2/17th Battalion was an infantry battalion of the Australian Army. Raised in April 1940 in New South Wales, the unit saw service in the Middle East in 1941–42, taking part in the fighting at Tobruk and El Alamein before returning to Australia early in 1943. In 1943–44 the battalion fought in New Guinea against the Japanese. Its final campaign was in Borneo in June 1945. Following the end of the war, the battalion was disbanded in early 1946.
