Melbourne teenager Bianca Jones has died in Thailand after drinking suspected methanol-laced spirits while on holiday in Laos.

Jones, 19, and her friend Holly Bowles were taken to separate hospitals in Thailand after consuming the tainted alcohol at a bar in the town of Vang Vieng last week.

Jones has died in hospital after several days on life support.

The pair were staying at the Nana Backpacker Hostel in Vang Vieng and drank at the hostel before they went on to drink at another bar on November 11.

They then did not leave their dorm room for 24 hours and failed to check out as scheduled last Wednesday before being taken to hospital.

It’s understood the Melbourne teens informed staff at the Nana Backpackers that they were feeling unwell.

“They come and tell my staff at the reception, the night shift, to bring them, go to hospital,” the Nana Backpackers hostel manager said.
