In October 1944, the 36th Battalion was placed under the command of the 6th Brigade and along with the 14th/32nd and 19th Battalions they moved by sea to the north coast of New Britain. Operating on the Gazelle Peninsula, the 36th Battalion took part in the Australian campaign of containment against the much larger Japanese forces that were in existence on the island at the time. In doing so, the battalion made a name for itself carrying out numerous long-range patrols and amphibious landings, becoming known as "Ike's Marines". In June 1945, after seven months on New Britain, the 36th Battalion was relieved and brought back to Australia in June 1945. It was disbanded in August 1945. Throughout its service during the war, the battalion lost 77 killed in action or died on active service, and 126 wounded. Members of the 36th Battalion received the following decorations: one Distinguished Service Order and 14 Mentions in Despatches. Four battle honours were awarded to the 36th Battalion for its involvement in the war in 1961.
