After the end of the war, "Westralia" was one of the ships at Ambon on 22 September 1945 for the surrender and occupation of the island where the 164 survivors of Gull Force prisoners had already been taken off on 10 September. She was later used for the repatriation of Australian troops, before being paid off in September 1946. The ship earned five battle honours for her wartime service: "Pacific 1941–45", "New Guinea 1943–44", "Leyte Gulf 1944", "Lingayen Gulf 1945", and "Borneo 1945".
