Once scorned by many of their countrymen, those who served in the Vietnam War will be honoured as Australia marks the 50th anniversary of the end of the nation’s involvement in the conflict.

Commemorative services will be held around the country today, including at the Vietnam Veterans Memorial at Torrens Parade Ground and the Australian Forces National Memorial in Canberra.

Veterans’ Affairs Minister Matt Keogh, representing Prime Minister Anthony Albanese who will be in Queensland, will deliver an address.

Governor-General David Hurley will pay his respects alongside Vietnamese Ambassador to Australia Nguyen Tat Thanh.

A fly-past of Vietnam-era aircraft will take place by the Historical Aviation Restoration Society.

In Adelaide, Vietnam veteran ex-service organisations including the RSL are holding a commemorative service today at 11am at the Vietnam Veterans Memorial at Torrens Parade Ground.

At 3pm, the time at which the Battle of Long Tan commenced on 18 August 1966, a Reflection Service will be held at the Memorial.

Red and yellow roses symbolising the colours of the Vietnamese flag will be placed on the memorial by members of the public to remember and honour those who died in the battle.

About 60,000 Australians served in Vietnam, with more than 3000 wounded and 523 killed. Some 15,000 were conscripted under the National Service Scheme.

Mal Thiele, the president of the Vietnam Veterans’ Federation said it is important to recognise the service of Vietnam veterans and take the time to honour the 523 Australians who didn’t make it home and ensure they are never forgotten.

“On this significant anniversary, I encourage the South Australian community to join Vietnam veterans and their families to remember those who fought, those who didn’t return and those who were forever affected by their service,” Thiele said.

Upon returning home, veterans experienced hostility from the community over their involvement in an unpopular conflict, including being spat on and having paint thrown on them during parades.

It is estimated more than 35,000 Australian Vietnam veterans are still living, with most aged 70 or older.

Albanese, who will attend a commemorative service in Ipswich, Queensland, paid tribute to their sacrifices.

“Their experiences during and after the war are a powerful reminder of the sacrifices made by those who have served our country and the debt of gratitude we owe each and every one of our veterans,” he said.

“It is important as Australians we know the stories of service in Vietnam and what our veterans faced when returned home.”

Keogh said when defence personnel were returning home from Vietnam, many felt unsupported and unrecognised.

“In marking 50 years since the end of Australia’s involvement in Vietnam, we honour and thank all those who served and the sacrifices of their families,” he said.

Opposition Leader Peter Dutton, together with defence spokesman Andrew Hastie and veterans’ affairs spokesman Barnaby Joyce, said the war was a polarising conflict.

“At the time, public opinion often failed to draw a distinction between the politics of war and the people who fought in it,” they said in a joint statement.

“In the decades since the Vietnam War, we have come to acknowledge our nation’s historical mistreatment of many who returned.

“And we have come to tell stories of the endeavours, valour and sacrifice of Australians who served in Vietnam – to see beyond the politics and rightfully honour the people, their character and their deeds.”
