The 62nd Battalion was an infantry battalion of the Australian Army. It was first raised in 1917 during World War I but was disbanded before seeing active service. During World War II the battalion was re-raised in 1942 as a unit of the Militia and was tasked with undertaking garrison duty in Dutch New Guinea, where they defended Merauke from possible Japanese attack. In 1944, the battalion was disbanded and its personnel distributed to units of the 9th Division as reinforcements.
