An offender advocating child sexual abuse has been stopped from attending church in Sydney, an inquiry into the Anglican Church has heard.
Dozens of other child abusers or people deemed to be a potential risk to children are allowed to worship in the Anglican Church but are monitored under safety plans, the child sex abuse royal commission has heard.
The Diocese of Sydney is managing 32 people on safety plans but its professional standards director Lachlan Bryant says two offenders have been deemed unsuitable to attend parishes.
"One of them is an offender who was essentially proselytising child sexual abuse," Mr Byrant told the royal commission on Tuesday.
"He's not welcome in our churches.
"He's not suitable for this protocol because it depends on his ability to maintain minimum standards.
"And another offender thinks it was a stitch-up. He doesn't think he's ever done anything wrong."
The inquiry heard the Sydney diocese went as far as seeking a court order to keep one offender out of a cathedral.
In Western Australia, the Anglican Church has 57 people on similar safety plans, there are 15-17 in the NSW dioceses of Grafton and Newcastle, and about 15 in the Melbourne diocese, the commission heard.
Grafton and Newcastle's director of professional standards Michael Elliott said he does not have great confidence that the church is able to manage persons of concern in its parishes well.
"I think that at a parish level, when you are dealing with complex offenders who are often adept at grooming and manipulation and they are within a vulnerable community, that it's exceptionally difficult to find people who have the skills to appropriately monitor and manage such persons of concern."
Some priests have to be convinced to allow an offender or person of concern to worship in their parish.
Diocese of Melbourne professional standards director Claire Sargent said she had also dealt with the opposite situation.
"A priest was so very keen to have somebody on an agreement because she thought that that was the right thing to do, that was the Christian thing to do," Ms Sargent said.
"She was working very hard to have this person who in the end was totally unsuitable and was not permitted to join."
