The 2/17th Battalion was an infantry battalion of the Australian Army. Raised in April 1940 in New South Wales, it formed part of the 20th Brigade, and was eventually allocated to the 9th Division. After completing basic training in Australia, the unit was deployed to the Middle East. In early 1941, it took part in the fighting at Tobruk, defending the port until relieved. A period of garrison duties followed in Syria and Lebanon before the battalion took part in the First and Second Battles of El Alamein in mid-1942. As the focus of the Australian Army's operations shifted to the Pacific theatre to fight the Japanese, the 2/17th Battalion returned to Australia early in 1943.
