Staff stood down over escape of Warrnambool child rapist Christopher Austin

Two people have been stood down from a Melbourne treatment facility after a child rapist escaped in an incident Premier Daniel Andrews has described as "appalling".

Christopher Austin, 22, from Warrnambool, absconded from Fairfield's Disability Forensic Assessment and Treatment Service on Tuesday night.

He remains missing.

Mr Andrews confirmed on Sunday two staff members from the facility had been stood down over the incident.

"What's gone on there is just appalling," he said.

"I won't offer any further comment because ... but yes, two people have been stood down and frankly so they should."

Austin was found guilty of the rape of a child in 2013 in and is serving a five-year sentence.

Minister for Housing, Disability and Ageing Martin Foley said Austin had scaled a large fence when he left the centre about 11.30pm on Tuesday.

"Apparently he managed to get over a five-metre fence and did so by leaping over four metres from the roof of nearby facility onto that fence," Mr Foley said.

"So he is a remarkably agile young man as well, apparently. But he's not well and he should return as soon as he possibly can.

"He is not a corrections prisoner, he is a disability client and we need to get him back not just for his safety but the wider Victorian community's safety."

An investigation will be held into the incident and a security check of the treatment facility is being conducted, Mr Foley said.

Austin has an intellectual disability and a long history of heavy drug abuse and criminal offending, dating back to when he was just 11 years old.

In 2013, Austin was found guilty of the rape of a young boy at a Warrnambool party the year before.

The court was told that the child had been left traumatised by the assault and showed symptoms including crying, rocking, repeating "I don't feel safe" and fear of men who looked like Austin.

The judge in that case, Judge Felicity Hampel, said Austin's own upbringing had been marred by physical, emotional and sexual abuse, and the court heard he was regularly sniffing petrol and paint when he was 10 years old.

Austin has dollar signs tattooed on his right leg and middle finger and also has two lines cut into his eyebrow.

He has short dark hair with a rat's tail and is 166 centimetres tall and of medium build.

Investigators say a man fitting Austin's description was spotted at 6am on Wednesday morning in Kew East.

"He was pushing a mountain bike along the Main Yarra Trail near Willow Grove, wearing shorts and a jumper," Acting Sergeant Melissa Search said.

Anyone who sees Austin is urged not to approach him, but to call Triple-0 immediately.
