Since the historic June summit between US president Donald Trump and North Korean leader Kim Jong-un, the remains of at least 55 servicemen have been sent to the United States.
Relatives are hoping some of the missing Australians are among them.
It is known as "the forgotten war."
But for a select group of Australian families whose relatives fought in the Korean War, it has never left their minds.
Julie Dorrington’s uncle, Don Ellis, was 23 years old and based in Japan with the Royal Australian Air Force when war broke out.
Just days before Christmas in 1950, his plane went down during a bombing raid near the North Korean capital, Pyongyang.
But she says they did not give up hope.
Of the 17,000 Australians who fought in the Korean War, 340 died.
But 43 Australian families have never been able to bury their loved ones, their bodies still missing in North Korea.
Now, there is renewed hope they could be returned home.
At the Singapore summit between Donald Trump and Kim Jong-un, the two leaders agreed to work together to repatriate the remains of all servicemen from the so-called allied forces.
Since then, 55 bodies, believed to be US remains, have been returned and are now being tested and identified.
Ian Saunders, whose father John Phillip Saunders went missing in action, has been on a tireless crusade to have his father's remains found.
He says almost 2,000 bodies were buried at US gravesites in Hawaii and South Korea immediately after the war and he wants those remains exhumed and, hopefully, identified.
“These remains exist on Allied soil," Mr Saunders said.
Ms Dorrington said she is hoping that her uncle’s remains are recovered.
"We are very hopeful that, now that relations seem to be improving between North Korea and the West, that we may be able to recover his remains. That would be my dearest wish."
