The original Long Tan Cross was gifted to Australia in 2017 and placed on permanent display at the Australian War Memorial in Canberra.

During the afternoon and evening of 18 August 1966, D Company of the 6th Battalion, Royal Australian Regiment (6 RAR) fought an intense battle with a much larger force of Vietnamese communist troops near Long Tân in South Vietnam.

According to an article in The Canberra Times, the cross was "the brainchild of Lieutenant Colonel David Butler and Warrant Officer James Cruickshank", and was constructed from concrete by New Zealand Army Corporal Barry McAvinue, attached to 6 RAR.

The next morning, infantrymen and assault pioneers cleared the area around the location where 11 Platoon of D Company had conducted a last stand during the Battle of Long Tan.

The ceremony concluded before noon, and 6 RAR returned to the nearby major Australian base at Nui Dat; D Company was the last element of the battalion to leave the site.
