A teenager has died in a Perth hospital after unwittingly consuming a drink containing methanol in Indonesia.

Liam Davies, 19, became sick after a new year celebration with friends on Lombok, near Bali.

He was flown back to Perth several days ago on the advice of doctors, but they were unable to save him.

Family members have described him as a fun-loving and active teenager, who had represented Australia in lacrosse and had dreams of seeing the world

They issued a statement on Friday warning others about the dangers of consuming locally-brewed alcohol in overseas countries when the quality could not be determined.

There has been a growing number of cases of methanol poisoning in Indonesia.

David Mountain, from the Australian Medical Association, says bars selling unregulated drinks should be prosecuted by Indonesian authorities.

"The bar owners that are selling these things really do need to have consequences, in Australia this would be manslaughter, if a bar actually did this to a patron," he said.

"They need to crack down on bootleg liquor sales which are unregulated, where you're likely to get methanol mixed in with alcohol.

"I'm sure there are hundreds of Balinese and Lombok residents as well who've been poisoned by these drinks and it'd be in everybody's interest to actually crack down on this."

Last year Perth rugby player Michael Denton died in Bali and an autopsy found the cause of death to be methanol poisoning.
