The family of Noelene Bischoff and her 14-year-old daughter Yvana says Bali police claim they've not ruled out criminal activity in the mysterious death of the pair.
The Bischoff family has requested autopsies be carried out in Australia, not Bali and have sought the release of the bodies from the Sanglah Hospital morgue.
Acting Australian Attorney-General David Crisafulli said the family had accepted an offer from Virgin Australia to fly the bodies from Bali to Brisbane, where the Queensland Coroner would lead an investigation into the deaths.
Yesterday Bali police said they found up to 30 different types of prescription medication in the pair's hotel room, including several allegery drugs.
News of the delay came as family and friends prepared to honour the pair a memorial service at the Caloundra CityLife Baptist Church today.
The church is on the same grounds as the Caloundra Christian College where Yvana went to high school.
Noelene Bischoff, 54, and Yvana died on Saturday, a day after they checked into the beachfront resort of Padang Bai in Karangasem, on the east coast of the Indonesian island.
Their family had been told at first that consumption of toxic fish might have caused their deaths.
Caloundra Christian College deputy principal Andrew Priaulx said Yvana was well-loved, having been a student at the school since her kindergarten days 10 years ago.
''Yvana was a delightful and bright young girl who was always happy,'' he said.
''She put other people first and had many friends. She was well known across the school.''
The college posted a Facebook message saying Yvana excelled in leadership and academic pursuits, including winning awards in maths, science and English competitions.
''Yvana will be remembered as a compassionate student who always placed the interests of others before her own,'' it says.
''She had a bright future and contributed significantly to the College Middle School program.''
The school will host another memorial service after the school holidays.
Meanwhile, former colleagues of Noelene Bischoff were mourning the loss of the highly respected and loved nurse.
Bischoff worked night shifts at Caloundra Hospital, where staff have remembered her ''wonderful and positive influence''.
''Noelene was an expert in nursing. She was highly qualified,'' staff said in a statement to the Sunshine Coast Daily.
''Her loss leaves us with a profound feeling of grief and pain and missing a colleague and dear friend, but having known Noelene, we have a true reference point for what a professional role model in nursing and life looks like.''
