Fire Support Base Balmoral was established on 24 May 1968, approximately 4.5 kilometres north of Fire Support Base Coral, during Australian operations in III Corps Tactical Zone following the Tet Offensive. The position was selected to support ongoing operations against North Vietnamese Army (NVA) forces operating in the area and to strengthen the Australian presence beyond their usual base of operations.

 

Unlike Coral, which had been rapidly established under pressure, Balmoral was deliberately planned and constructed as a strong defensive position. The base featured a compact and coordinated layout. Infantry units formed a continuous perimeter, artillery was positioned centrally to provide all-round fire support, and Centurion tanks were integrated into the defensive system. This combination of infantry, artillery, and armour created overlapping fields of fire and significantly improved the base’s ability to respond to attack.

​

On the nights of 25–26 May and again on 28 May 1968, Balmoral came under sustained assault from NVA forces. Advancing under cover of darkness, enemy troops moved across cleared ground toward the perimeter. Australian defenders responded with coordinated firepower, including artillery barrages, machine-gun fire, and direct fire from tanks. The presence of Centurion tanks proved decisive, delivering heavy fire at close range and disrupting enemy formations before they could breach the perimeter.

In each assault, the attacks were repelled with heavy enemy losses, and the integrity of the base was maintained. Unlike the earlier fighting at Coral, where combat had occurred within the perimeter, the defence of Balmoral prevented the enemy from gaining entry to the position.

The successful defence of Fire Support Base Balmoral demonstrated the effectiveness of a well-planned and integrated defensive system. It reflected the rapid adaptation of Australian forces under combat conditions and highlighted the importance of coordination between infantry, artillery, and armour in modern warfare.
