Indonesian authorities say they haven't found evidence to suggest the deaths of a Queensland mother and her teenage daughter at a Bali resort were the result of a crime.
The bodies of Caloundra nurse Noelene Bischoff, 54, and her daughter Yvana, 14, will be flown to Brisbane on Friday night and arrive on Saturday morning.
The close-knit mum and daughter died on January 4 after becoming violently ill, less than 24 hours after checking in at a beachfront resort on the east coast of the island.
Food poisoning, allergic reactions and intoxication from drugs have been suggested as possible causes.
Indonesian authorities refused to release the pair's bodies on Thursday because they couldn't rule out whether criminal activity was involved in their deaths.
However, on Friday Indonesian police said the bodies would be flown to Australia, after they found no evidence of crime.
About 30 types of medicines were found in their hotel room by Indonesian police and laboratory results of vomit from the scene came in on Friday.
Detective Superintendent Adnan Pandibu, who is leading the investigation in Indonesia, told AAP no toxins were found, and the deaths didn't appear to be suspicious.
"The main point is that the investigators haven't found preliminary evidence that a crime has happened," he said.
"As the family requested, the bodies will be sent back to Australia today."
A spokesman for Virgin told AAP the bodies were due to be flown into Brisbane just after 5am (AEST) on Saturday and taken to the John Tonge Centre in Coopers Plains for autopsies.
