while D Company patrolled south. C Company remained at LZ Queen to protect 105 Field Battery which had established a fire support base (FSB). Over the next two days the Australians patrolled relentlessly through the leech-infested swamps and dense jungle. At midday on 6 November A Company received two mortar rounds which failed to do any damage, but marked the start of a series of minor clashes. A Company had a number of contacts during this time, with the Australians killing a Viet Cong scout for the loss of two wounded in one skirmish. A further contact soon after resulted in two more Viet Cong killed and one wounded. Intelligence gained from these incidents indicated the presence of a Viet Cong Main Force Regiment in the area, while documents recovered contained plans for attacks on ARVN outposts near Bien Hoa Air Base. By nightfall on 7 November, despite the earlier contacts, no major actions had occurred in the Australian AO. With the rifle companies now several kilometres apart, A Company had patrolled into a network of well used roads and tracks.

Meanwhile, although unknown to them at the time, the US 1/503rd Battalion across the Song Dong Nai had patrolled to within of a major Viet Cong bunker system sited on two spur lines in the vicinity of Hill 65.

With contact now seeming unlikely to the Australians, Healy was instructed to move to a rendezvous from which the battalion would be extracted back to Bien Hoa the following day. A Company subsequently set out on a compass bearing which would take them across the northern edge of the Gang Toi plateau. By 10:30 the Australians moved out in single file but had not gone far before a lone Viet Cong scout was observed shadowing them; he was subsequently shot and killed by the rear section. Crossing a creek line the Australians uncovered a company-sized camp of dugouts and trenches, before being fired upon at 15:40 by a single Viet Cong soldier who then fled. A Company halted briefly, and at this time two Viet Cong approached their
