Situated north of the 1st Australian Task Force base at Nui Dat on the western side of Route 2, the village of Binh Ba had a population of around three thousand people – mainly farmers and rubber plantation workers. Tidy and rectangular in shape, and mainly constructed of solid brick and tile, Binh Ba was well known to the Australians. Indeed during 5RAR's first tour in Vietnam a rifle company and a mortar section had been briefly stationed within the village itself. This strategy proved to be a deterrent to the Viet Cong tax collectors and assassination squads taking control of the village. The drain on the finite resources of the small Australian force proved to be too much however, and the village was later left to the protection of South Vietnamese Regional Forces. In an attempt to demonstrate that they could move freely within the province, a combined communist force including the 1st Battalion NVA 33 Regiment, elements of the VC D440 Local Force Battalion, the Binh Ba and Ngai Giao Guerrilla Squad and the Chau Duc District Company had occupied Binh Ba on the evening of 5–6 June 1969. In response, South Vietnamese forces were sent from Duc Thanh the following morning. Initial intelligence suggested that a group of about platoon strength had infiltrated the village. Meanwhile during a separate operation 6RAR had also been engaged in a heavy contact several kilometres north of the task force base and at 0800 on 6 June, an Australian Centurion tank and an armoured recovery vehicle moving through Binh Ba to assist 6RAR were fired upon. A rocket propelled grenade struck the Centurion penetrating the turret, and causing damage to the tank and severe wounds to one of the crewman. The district commander subsequently asked 1 ATF for assistance in clearing Binh Ba.
