Of all the gruesome conflicts of the Vietnam war, the battle of Long Tan is etched deeply in Australians' memory.
On the 18 August 1966, a few hundred troops fought off thousands of Vietnamese soldiers in torrential rain.
Australian soldiers then returned to erect a cross to all the men who fell there, including the Vietnamese.
Now that cross, the battlefield original, is being displayed in Australia for the first time.
