Colonel Donald Dunstan, later to be governor of South Australia, was the deputy task force commander of the 1st Australian Task Force (1 ATF) in South Vietnam Dunstan had quite possibly been the last Australian to use tanks and infantry in a combined operation during the Second World War, (as part of the Bougainville campaign), and the first since the war to command Australia's tanks and infantry in combat. When he temporarily took over command during Brigadier Ronald Hughes's absence, he directed that the Centurions be brought up from Nui Dat to reinforce firebases "Coral" and "Balmoral", believing that they were a strong element that were not being used. Besides adding a great deal of firepower, Dunstan stated, he "couldn't see any reason why they [the Centurions] shouldn't be there". His foresight enabled 1 ATF to kill approximately 267 soldiers from the 141st and 165th North Vietnamese Army Regiments during the six-week-long Battle of Coral–Balmoral in May 1968, as well as capturing 11 prisoners, 36 crew-served weapons, 112 small arms, and other miscellaneous enemy weapons.
