He acknowledged steps being taken by Warrnambool's Emmanuel College to recognise the failure of leaders within the Catholic Church in responding to reports of historical sexual abuse.

Plaques about those failings will be unveiled at the Canterbury Road Rice Campus next Tuesday.

"I've got no problems with what Emmanuel is doing," he said.

"But, the original plaque has to go.

"There are no plaques in Germany saying what good blokes Hitler and Himmler were," he said, referring to Nazi masterminds Adolf Hitler and Heinrich Himmler. 

The victim called for the removal of all plaques honoring both former Bishops of Ballarat Ronald Mulkearns and James O’Collins.

"It’s idiotic to keep the plaque honouring Mulkearns - they simply must go from everywhere," he said, explaining there were still plaques honoring Bishop O’Collins in Ballarat, who  pedophile priest Gerald Ridsdale served under.

The victim said Victoria Police estimated there were potentially hundreds of children abused by former western Victorian priests Ridsdale and Monsignor John Day.

He said former Ballarat bishops O’Collins and Mulkearns facilitated the abuse of each victim under the banner of the church. 

"These are places that attempt to educate and care for children. A plaque with either of their names on it has no place," he said.

The victim said plaques had been removed or altered across western Victoria, including at Warrnambool, Koroit, Mortlake, Timboon and Noorat.

It's understood there still remains a plaque honouring former Bishop Mulkearns at Our Lady Help Of Christian in east Warrnambool.

"I talked about this at a survivors gathering last week and everyone there completely agreed," he said.
