The Catholic Church has handed to police a report detailing allegations of sexual assault and grooming against a former West Australian bishop.
The Vatican report found Bishop Christopher Saunders hosted "bunga bunga" parties at church properties in Broome, the Seven Network reported.
He also allegedly spent thousands of dollars in church money on cash payments, mobile phones, alcohol and cigarettes.
The Vatican identified 67 Aboriginal boys and young men who may have been subjected to sexual assault or grooming by Bishop Saunders.
He has denied the allegations and has not been charged by police but resigned from his role in Broome in 2020 after sexual misconduct and bullying claims emerged.
The Australian Catholic Bishops Conference on Friday confirmed it had provided the Vatican report to the WA Deputy Commissioner of Police.
Police would not confirm whether the report had been received.
Bishop Michael Morrissey, the Broome diocese's apostolic administrator, said the church would continue to be transparent and co-operate with police.
"The church encourages anyone who has experienced abuse, or suspects abuse within the community, to come forward and report it to police," he said.
The church clarified Bishop Saunders refused to leave the Broome diocese during its internal investigation and he also chose not to participate in questioning.
The Catholic Church denied it breached its mandatory reporting obligations and rejected any suggestion it opposed providing the Vatican report to police.
The 200-page Vos Estis Lux Mundi investigation found Bishop Saunders developed a "modus operandi" of grooming young Aboriginal men for sex during his time in the Kimberley region.
WA Police confirmed it carried out two investigations into a number of complaints regarding a member of the Catholic Church in the Kimberley between 2018 and 2020.
There was insufficient evidence to lay criminal charges.
"Offences of a sexual nature are complex and challenging to prosecute," a spokeswoman said earlier this week.
"In all instances, the welfare of complainants is of the utmost importance."
