A survivor of the notorious Christian Brothers-run Bindoon orphanage in Western Australia says redress isn't so much about money, it's about knowing the truth has finally come out.

John Hennessey was taken away from his mother at birth and in 1947 sent to Australia at the tender age of 11.

She'd been banished from Ireland to England because she was pregnant out of wedlock - and was told he had died.

It wasn't until he was aged 62 that they were reunited, thanks to the Child Migrants Trust.

Over those lost years, he repeatedly begged the same Christians who had abused him to help him find his mother, but they refused.

Speaking with a stutter he developed at age 12 after a severe bashing by Brother Keaney, Mr Hennessey said the church had once again let him down.

They'd promised to seek out victims and offer help after hearings for the Royal Commission into Institutional Responses to Child Sexual Abuse last year, but not done so.

"Up to date, I have not had a word from anybody," Mr Hennessey told AAP.

Speaking after the Royal Commission's launch last week of a landmark consultation paper that outlined models for a multi-billion dollar compensation scheme, Mr Hennessey said the money would go some way to helping victims.

"But we just want to see justice.

"We've got to take these scars to the grave. You just can't move on. We've tried to survive in the circumstances."

He said he was buoyed by how moved Commissioner Peter McLellan appeared by victims' stories.

"He listened to us intently.

"You could see there were almost tears in his eyes.

"The commission could see the hurt doesn't last just a few years - it's with you."

Giving evidence to the Royal Commission had been the hardest thing he'd ever done, but he'd keep attending the proceedings, watching the church being "dragged kicking and screaming to do the right thing".

"I had nightmares before but as soon as it was done, the chains were taken off me.

"It's almost like a mission, a sense of cleansing.

"I'm a little bit happier today."
