An Australian teenager has died after drinking tainted alcohol in Laos in what Australia’s prime minister called every parent’s nightmare.

An American and two Danish tourists also died after reports that multiple people had been fallen ill in a town popular with backpackers.

Australian Prime Minister Anthony Albanese told Parliament that 19-year-old Bianca Jones died after being evacuated from Vang Vieng, Laos, for treatment in a Thai hospital. Her friend, also 19, remains in hospital in neighbouring Thailand.

“This is every parent’s very worst fear and a nightmare that no one should have to endure,” Mr Albanese said. “We also take this moment to say that we’re thinking of Bianca’s friend Holly Bowles who is fighting for her life.”

They are believed to have consumed drinks tainted with methanol, which is sometimes added to mixed drinks at disreputable bars as a cheaper alternative to ethanol, but can cause severe poisoning or death.

Australia said “several foreign nationals” had also been victims of methanol poisoning.

The US State Department confirmed that an American had also died in Vang Vieng, and Denmark’s Foreign Ministry said two of its citizens also died in “the incident in Laos” but neither would comment directly on a link to the methanol poisoning that killed Ms Jones.

Shaun Bowles told reporters outside Bangkok Hospital on Wednesday that his daughter remained in a critical condition and on life support.

“We just like to thank everyone from back home for all of the support and love that we’re receiving,” he said. “But we’d also like the people to appreciate right now, we just need privacy so we can spend as much time as we can with Holly.”

In a statement to the Melbourne Herald Sun newspaper, Ms Jones’ family asked for privacy in their grief.

“She was surrounded by love, and we are comforted by the knowledge that her incredible spirit touched so many lives during her time with us,” the family wrote.

“We want to express our deepest gratitude for the overwhelming support, love, and prayers we’ve received from across Australia.”

The US State Department said local authorities were investigating the case and were responsible for providing any details, and that the US was providing consular assistance.

“We offer our sincerest condolences to the family on their loss,” the State Department said.

Landlocked Laos is one of south-east Asia’s poorest nations and a popular tourist destination. Vang Vieng is particularly popular among backpackers seeking partying and adventure sports.

Details on the alcohol poisoning began trickling out about a week after the two Australian women fell ill on November 13 following a night out drinking with a group in the remote town.

Thai authorities confirmed that Ms Jones had died by “brain swelling due to high levels of methanol found in her system”.

“Drink spiking and methanol poisoning are far too common in many parts of the world,” Australian foreign minister Penny Wong said after receiving news of Ms Jones’ death.

“At this time I would say to parents, to young people, please have a conversation about risks, please inform yourselves, please let’s work together to ensure this tragedy doesn’t happen again.”
