The 57th/60th Battalion was an infantry battalion of the Australian Army which served during the Second World War. It was formed in 1930 as part of the Militia by the amalgamation of the 57th and 60th Battalions and was assigned to the 15th Brigade, 3rd Division in Victoria. Following the outbreak of the war, the battalion was initially used in a garrison role in Australia before being deployed to New Guinea in 1943, remaining there for almost 18 months before being brought back to Australia. Later, in mid April 1945 the battalion embarked for Bougainville where they took part in the advance towards Buin in the southern sector of the island. Following the end of hostilities the battalion was disbanded in March 1946.
