Northern Territory coronial officials are preparing a new inquest into the death opf Azaria Chamberlain 30 years after her disappearance at Uluru.
The inquest - the fourth since Azaria disappeared on August 17, 1980 - is likely to be established early next year and will examine whether the baby was taken by a dingo, Fairfax newspapers say.
Azaria's father Michael Chamberlain said his lawyers are preparing a case that will lead to a coroner finding that a dingo took his baby, including evidence of six attacks on humans by
dingoes since 1980.
Her mother Lindy Chamberlain-Creighton called for a new inquest on the 30th anniversary of Azaria's disappearance earlier this year.
Dr Chamberlain has called for the inquest to investigate the NT's handling of the case, including Lindy's 1982 murder conviction.
"There were many unfortunate things that happened in the Northern Territory, whether by ignorance or a kind of plan to take us, come hell or high water," he said.
Dr Chamberlain said he wants the findings of a 1995 coronial inquest quashed. It returned an open verdict on Azaria's death.
Official NT sources told Fairfax the moves are underway to prepare for a fourth inquest in Darwin early in the new year.
Nine-week-old Azaria went missing from a tent at Uluru and the case gripped Australia.
Lindy Chamberlain was initially convicted of murder and served three years in jail before a royal commission and a new trial exonerated her.
