Bathurst and District Vietnam Veterans Association president John Murphy said the service was well attended by the community.

"We had around 150 people there, which was a welcome turnout for us," Mr Murphy said.

Mr Murphy said the service recognises the dutiful efforts of soldiers who lost their lives in the Vietnam War and veterans who continue to carry the scars of the conflict.

"We know there are veterans who are still suffering in silence as a result of the experience," he said.

"We're fortunate enough to have an association involving regular catch-ups, as it's very difficult to explain the Vietnam War to people who weren't there."

While the Vietnam War ended in 1975, Australian veterans faced a home-grown battle to receive recognition for their service, resulting in the 1987 'Welcome Home' parade in Sydney.

"Some veterans were rejected in their own RSL clubs, but thankfully things have turned around in recent years," Mr Murphy said.

"We're now stopped in the street and thanked for our service."
