They were withdrawn from the front in March 1944, for rest and re-organisation, subsequently returning to the Atherton Tablelands to concentrate near Ravenshoe where a long period of training followed. The battalion's final involvement in the war came when they were committed to Operation Oboe, the Allied operation to re-capture Borneo. Embarking upon the transport "Frederick Lykes", the battalion concentrated on Morotai Island in April 1945, along with the rest of the 7th and 9th Divisions, the 2/13th Battalion was committed to the Battle of North Borneo on 20 June when it conducted an unopposed amphibious landing at Lutong on 20 June, before undertaking another landing and continuing their advance down the south-western coast, passing through Miri on 23 June, before continuing on to Seria on their way towards Kuching, securing several airfields and oilfields, and conducting patrols, as they went. The campaign ended with news of the Japanese surrender, following the atomic bombings of Hiroshima and Nagasaki, by which time the 2/13th had established itself around Lobang.
