Federal police have referred information relating to allegations money was wired from the Vatican to Australia in relation to Cardinal George Pell's trial to Victoria's anti-corruption watchdog.
The High Court quashed Cardinal Pell's child sex abuse convictions earlier this year.
On Wednesday, the Australian Federal Police (AFP) confirmed it had received "information" from the federal financial crimes regulator AUSTRAC regarding the allegations.
"This is part of a routine exchange of financial intelligence between AUSTRAC and the AFP," the agency said.
The AFP said it was reviewing the information, and had also referred "aspects" of the matter to Victoria's Independent Broad-based Anti-corruption Commission (IBAC).
Earlier this month, Italian newspapers reported unsubstantiated allegations that Cardinal Giovanni Angelo Becciu was suspected of wiring 700,000 euros ($1.14 million) to Australia to help secure evidence against Cardinal Pell in his sexual abuse trial.
Cardinal Becciu has strongly denied interfering in Cardinal Pell's trial.
In a Senate Estimates hearing on Tuesday, AUSTRAC's chief executive Nicole Rose was asked about media reports that hundreds of thousands of euros had been transferred "allegedly from Vatican funds to person or persons in Australia".
"Yes, I can confirm AUSTRAC has looked into the matter, and we've provided information to the AFP (Australian Federal Police) and to Victoria Police," Ms Rose told the committee.
IBAC is the Victorian agency responsible for investigating public-sector corruption and police misconduct.
Its jurisdiction includes state and local government, police, parliament and the judiciary.
In a statement, IBAC said: "For legal and operational reasons we are unable to comment on this matter."
