 The Battle of Wareo (27 November – 8 December 1943) was fought by Australian and Japanese forces in New Guinea during the Huon Peninsula campaign of World War II in the later part of 1943. Coming after the capture of Sattelberg by the Allies, the battle took place amidst the Australian advance north towards Sio. The Australians committed elements from four infantry brigades from the Australian 9th Division with supporting elements including artillery, engineers and tank support, while the Japanese force consisted primarily of two depleted infantry regiments from the 20th Division, with limited artillery support.
