ANALYSIS: HOW DID NOELENE AND YVANA SUDDENLY DIE IN BALI?

Indonesian authorities decided to respect the Bischoff family's request that autopsies not be done in Bali and instead undertaken in Australia.

But Comm Pandibu said Bali police would continue their investigations into the deaths and would co-ordinate with Australian Federal Police.

"As requested by the family the bodies will be returned to Australia. Investigators are yet to find any evidence of crime in this case," he said.

"We will continue co-ordinating with Australian police".

Authorities initially speculated that severe food poisoning or an allergic reaction to seafood the had eaten for lunch or dinner may have been to blame.

There were no physical signs of injury and authorities say an autopsy is needed to uncover the truth.

Bischoff family spokesman Mal Brough thanks the community for their support in the wake of the deaths of Noelene and Yvana Bischoff in Bali.

The Sunshine Coast pair arrived in Bali on December 31 for a holiday. But just four days later, at their hotel on Bali's east coast, they fell suddenly ill and within hours both had passed away.

Their last day in Bali was Friday last week and the driver who showed them around for seven hours says the pair was healthy and happy and showed no signs of illness when he dropped them off at the hotel at 3.50pm.
