Start the trip with Long Phuoc Tunnels system in Long Phuoc commune, Ba Ria town. These tunnel clusters are interconnected by spine route, with secret tunnels containing reserved food with the fighting fortifications. We will go to the site of Long Tan Battlefield where you will visit the former first Australian Task Force at Nui Dat. In a somber moment, we will visit Long Tan Cross Memorial established at Long Tan for the 17 Australian Infantrymen and 1 APC crewman killed in action during the Battle of Long Tan on August 18, 1966.The cross was first erected on the site in 1969 when the 6th Battalion, the Royal Australian Regiment, which fought in the Battle, was on its second tour of duty. In 1986 a replica of the cross was placed on the original site. In 2017, the Vietnamese Government gifted the original cross to Australia, and it is now on display at the Australian War Memorial in Canberra. We then visit Nui Dat Hill which is a former 1st Australian Task Force (1ATF Base), including Luscombe Airfield, this was home to the Australian military during the Vietnam War.
