Holly Bowles and her best friend Bianca Jones had been holidaying in Laos when they became unwell after consuming the drinks in the tourist town of Vang Vieng.
Ms Bowles died in a Bangkok hospital on November 22, a day after Ms Jones died in another hospital in the Thai capital.
A funeral service for the 19-year-old will be held at Beaumaris Secondary College on Monday.

Ms Bowles' family has asked people to donate to the girls' GoFundMe in lieu of flowers.
The fundraiser has received more than $400,000 and was to help with the families' financial burdens before being expanded to help raise awareness about the dangers of methanol poisoning.
Ms Jones was farewelled in an emotional service attended by more than 1000 community members at Mentone Girls Grammar on Friday.
The Melbourne school's grounds were awash with guests in colourful summer clothes, the way Ms Jones' family said she lived her life and how she would wish to be remembered.
Her parents vowed to continue the two friends' legacy by raising awareness of methanol poisoning.
"We hope their stories drive change and inspire efforts to save lives to support our ongoing mission," they said in a statement.
The pair did not leave their dorm at the Nana Backpacker Hostel 24 hours after going to Jaidee Bar in Laos and reported feeling unwell on November 13, before being rushed to hospitals in Bangkok.
An American man, two Danish women and a British woman were among the six foreign nationals who died and at least eight people, believed to be hotel staff and management, have been detained.
