The 60th Battalion was an infantry battalion of the Australian Army. It was raised for service during World War I in 1916 and took part in the fighting on the Western Front for two-and-a-half years. Following the end of the war it was disbanded before being re-raised in 1921 as a part-time unit of the Citizen Force. In 1930, as a result of manpower shortages, the 60th was amalgamated with the 57th Battalion to form the 57th/60th Battalion and this unit subsequently saw service in the South West Pacific during World War II fighting against the Japanese, before being disbanded in 1946.

The 57th Battalion was an infantry battalion of the Australian Army. Formed in early 1916 for service during World War I, the battalion served on the Western Front until the end of the war, when it was disbanded. In 1921, it was re-raised as a part-time unit in Victoria, known as "The Merri Regiment". In 1930, the battalion was amalgamated with the 60th Battalion, to form the 57th/60th Battalion, which remained linked until it was disbanded in 1946, after having fought against the Japanese in New Guinea and Bougainville during World War II.
