Two Melbourne mates have died “tragically” while holidaying in Vietnam, with their families reaching out for help to bring back their remains.

Vincent Atulia, 24, and Andrew Colivas, 25, were believed to be travelling with friends, the Herald Sun reports.

Their families paid tribute to the men while launching separate appeals on GoFundMe for help with costs.

The cause of their deaths has not been revealed.

“It is with heavy hearts and deep sorrow that we announce the sudden and tragic passing of our beloved son, brother and friend Vincent Satuala Atulia,” wrote relative Naomi Atulia.

“Vincent tragically passed away whilst on holiday in Vietnam and unfortunately had not obtained adequate travel insurance.”

Naomi said Vincent, a labourer, was devoted to his family, friends and God and had always cared for others before himself.

“He gave his life to provide and protect for his loving family,” she wrote.

He was a faithful member of St. Agatha Church Parish Cranbourne and an aspiring rugby player for the Casey Warriors rugby league team.

“Vincent was also the sole financial provider to his family,” she said.

“This GoFundMe page will allow the Atulia family to bring their son home to Melbourne, Australia where he’ll be laid to rest peacefully.”

On Wednesday morning, $53,000 had been raised.

The Colivas family also shared the sad news of Andrew Colivas’ “untimely passing” on GoFundMe.

“He tragically lost his life in Vietnam and it’s going to be a long process to bring him home,” wrote Nick Colivas.

“Andrew was only 25 and had a passion for boxing. He was a kind, generous and selfless person that loved his family, friends and all things he attempted in life.

“Andrew was one to go above and beyond to help and protect anyone.

“He was a dedicated member of Saint Gregorios Orthodox Church and was devoted to his faith.

“We pray for strength during this time of grieving, may God bring you back home safely to us.”

A spokesman for the Department of Foreign Affairs and Trade told the Herald Sun it was providing consular assistance to the family of a man who had died in Vietnam and to three other Australians.

“We send our deepest condolences to the family at this difficult time. Owing to our privacy obligations we are unable to provide further comment,” the spokesman said.
