The 2/28th Battalion was an infantry battalion of the Australian Army, which served during the Second World War. Formed in mid-1940 from Western Australian volunteers, the battalion served in North Africa in 1941–42 as part of the 24th Brigade, which was assigned to the 9th Division. In early 1943 the battalion returned to Australia and later took part in campaigns against the Japanese in New Guinea in 1943–44 and Borneo in 1945, before being disbanded in 1946.
