The aftershocks from the latest sex abuse scandal continue to shake the Catholic Church, with another victim alleging the church turned a blind eye to his complaints.

Four Corners revealed last week that a Catholic Church priest accused of sexual abuse made admissions to three senior priests about his actions, but the priests never referred the matter to police.

The priest, known as Father F, worked in Moree and then later in Parramatta, where it is alleged he abused a number of altar boys in the 1980s.

Now, 7.30 has learned of another alleged victim of Father F. The man says he was abused when he was an altar boy at Moree in the mid-1980s.

Bill, who does not want to be identified, says he would sometimes wake to Father F abusing him.

"The abuse ranged from touching you to you touching him. The other times it would happen in your sleep. You would wake up with him doing things to you," he said.

"I mean, there were times that there was a roomful of people. He was quite well-known for kind of tapping his legs and kids would come and sit on his knees or whatever and he would take the chance while someone turned their head just to touch you.

"I can still remember to this day feeling sick every time, feeling like my legs were going to collapse, those kind of things."

Father F's sordid history was discussed at a 1992 meeting at Sydney's St Mary's Cathedral, when he was called before three of the church's most trusted clergy: fathers Brian Lucas, Wayne Peters and John Usher.

The church hierarchy has since given conflicting accounts of what happened at that meeting.

Australia's most prominent Catholic, Archbishop George Pell, defended the three priests on Four Corners by saying that Father F made no admissions and "that is the recollection of the three priests".

But in a letter written just days after the 1992 meeting, Father Wayne Peters detailed Father F's admissions, saying the priest had admitted to touching and fondling five boys and that he had performed oral sex on two of them.

Father Lucas also says admissions were made.

In an affidavit, Bill's mother said she had told the local monsignor of the abuse in 1986. The church did not tell police and they did not follow up with Bill's mother.

Bill wrote to Archbishop Pell in 2002 detailing his abuse. Archbishop Pell wrote back that he had no jurisdiction and advised Bill to go to the police.

Lawyer Andrew Morrison, who has represented church abuse victims, thinks there is enough evidence to charge the three priests at the 1992 meeting with concealing an offence.

"Any citizen who becomes aware of information which causes them to reasonably believe that a serious criminal offence has occurred has a duty in law to go to the police or other appropriate authority and disclose all they know about it," he said.

"Telling the victim to go to the police does not answer that duty."

After Four Corners went to air last week the Catholic Church released a statement saying the Archdiocese of Sydney is seeking further information about the 1992 meeting.

The Catholic Bishop of Armidale also said last week that he would fully investigate the abuse claims raised by Four Corners.
