The Australian woman who suffered internal burns after drinking a cocktail in Indonesia is being flown from Darwin to her home in New South Wales.

It is thought Jamie Johnston's drink was contaminated with methanol at a restaurant on the island of Lombok, near Bali.

Careflight has confirmed it will transfer the patient to John Hunter Hospital in Newcastle tonight.

Earlier, NSW Health Minister Jillian Skinner said the 25-year-old spent several days in medical centres in Bali before being evacuated to Darwin.

Ms Skinner said Ms Johnston had no travel insurance, and her mother has spent a considerable amount of money just getting her to Darwin.

"I am now trying to get her help in getting airlifted back to Newcastle so she can be admitted to John Hunter Hospital, where she is actually a nurse herself," Ms Skinner said.

"The warning for everyone is just be careful about what you drink and eat and if you do become ill, immediately seek medical help. The fact that there was some delay here was problematic for her."

The Minister says it is also a reminder of the importance of insurance.

"I understand young, fit people think 'It won't happen to me', but you just never know do you?" Ms Skinner said.

"This is really important to get back home, to treatment that you trust, close to family and friends."
