The 35th Battalion was an infantry battalion of the Australian Army. Originally raised in late 1915 for service during the First World War, the battalion saw service on the Western Front in France and Belgium before being disbanded in 1919. In 1921, it was re-raised in the Newcastle region of New South Wales as a unit of the Citizens Force (later known as the "Militia"). It was subsequently amalgamated a number of times during the inter-war years following the Great Depression, firstly with the 33rd Battalion and then the 2nd Battalion, before being re-raised in its own right upon the outbreak of the Second World War. Following this the battalion undertook garrison duties in Australia before being deployed to New Guinea where they took part in the Huon Peninsula campaign. After the end of the war, the 35th Battalion was disbanded in early 1946.
