The 16th Battalion, Royal Western Australia Regiment (16 RWAR) is an Australian Army reserve infantry battalion located in Western Australia and one of the two battalions of the Royal Western Australia Regiment. The battalion was first formed during the First World War, during which it fought during the Gallipoli Campaign and on the Western Front in France and Belgium as part of the Australian Imperial Force. It was re-formed as a part-time unit in Western Australia during the inter-war years, and served in the New Britain Campaign against the Japanese during the Second World War. In the post war years, the battalion became part of the Royal Western Australia Regiment and currently forms part of the 13th Brigade.
