Britt Lapthorne's family will seek independent tests on her body by the Victorian coroner after a Croatian autopsy report gave no insight into how the Australian backpacker died.

Ms Lapthorne's father Dale said a brief autopsy report released in Dubrovnik today described the condition of his daughter's body, but was inconclusive on the cause of death.

"There is no visible sign of an act of death because the body is in such a poor condition," Mr Lapthorne said.

"There is nothing in the report from the translation made to us that indicates accidental death or death by other means, they cannot determine."

Police announced on Friday that DNA tests had confirmed a body found off the coast of Dubrovnik on October 6 was that of the 21-year-old Melbourne student.

She had gone missing 18 days earlier.

Ms Lapthorne's body has been released to her family, who plan to bring her back to Australia this week.

"The arrangements are being made to go to a funeral director," Mr Lapthorne said.

"The body will not be preserved as would normally be the case because they are aware that further pathological tests will be undertaken by the Victorian coroner.

"The body will be picked up by the Victorian coroner at the airport.

"I have been assured that any investigation carried out by the coroner's department in Victoria will be a very thorough scientific investigation at very high level.

"They said if your imagination is CSI that's what the Victorian coroner's office is like," Mr Lapthorne said.

Croatian police were expected to hold a press conference at 2pm local time (2300 AEDT).

"The principal objective was to take her home alive," said Mr Lapthorne.

"We did not do that ... at least we have the consolation that we can take her home."

Mr Lapthorne and son Darren travelled to Dubrovnik to find Ms Lapthorne after she disappeared.

Ms Lapthorne's mother Elke has stayed in Melbourne.

The family believe Britt is the victim of foul play and reject any suggestion she jumped or fell off the cliff above the cove where the body was found.
