On 1 June 1944, the unit was renamed the 1st Armoured Regiment. The unit then spent the next year in training, and during this time it was based at Southport, Queensland. In May 1945, it took part in the amphibious landings at Balikpapan in support of the 7th Division, being involved in one of the final Australian campaigns of the war in Borneo. The landings took place on 1 July 1945 and had been preceded by heavy bombing and shelling by Australian and US air and naval forces. Landing with the infantry, the tanks—including newly modified Matilda Frog flamethrower tanks—mainly operated in small detachments in close support of the troops, even though the terrain offered the opportunity for more mobile tactics to be employed. Although the Australians were ultimately successful, casualties among the infantry were heavy and during this time the regiment was involved in some hard fighting, with the Japanese able to make effective use of strong natural defences in conjunction with minefields and anti-tank ditches in order to compensate for their lack of anti-tank guns. With the fighting coming to a conclusion however, tank operations ceased on 24 July. In total, casualties suffered by the regiment during the war included 14 dead.
