There are calls for a paedophile priest to be forced to give evidence about the Catholic Church to two inquiries.

Gerald Ridsdale was sentenced to a maximum of 25 years in jail for molesting at least 40 children but he could be eligible for parole in June.

Judy Courtin represents a number of Ridsdale's victims - many of them were abused at Ballarat's St Alipius school.

She says if he gets an early release he should be subpoenaed to speak at the royal commission and the Victorian parliamentary inquiry into institutional abuse.

"I would highly encourage both inquiries call Ridsdale and other offenders for that matter," she said.

"We all know Ridsdale was moved from parish to parish and his insight and his knowledge of the workings of the hierarchy of the church would be very valuable evidence for both inquiries."

There are fears the early release from prison would traumatise Ridsdale's victims.

Ms Courtin says she has grave concerns about the effect an early parole would have on the men.

"This is going to be highly problematic," she said.

"It will, without a doubt, bring up for the victims and the survivors their shocking experiences.

"Although this man has served his time, the ongoing sort of trauma and suffering for victims - that doesn't stop, that will go on."
