Former Marist Brothers teacher admits indecently assaulting students.

By Nick Dole.

A former Catholic school teacher has pleaded guilty to a string of indecent assaults involving students in northern New South Wales in the 1970s and ’80s.

Darcy John O’Sullivan, known as Brother Domenic, was a teacher at Marist Brothers in Hamilton, Newcastle, and a principal at St Mary’s High School in Casino, where the offences took place.

Court documents have detailed numerous offences were committed against teenage boys at Marist Brothers, which involved O’Sullivan inappropriately touching his victims.

One victim told police he could not report the abuse at the time because “his mother was a staunch Catholic and he knew, as a child, that she wouldn’t believe him”.

Victim blamed after telling mother of abuse

In 1978, O’Sullivan moved to St Mary’s High School in Casino where he continued to abuse teenage boys.

Some students at the time had a saying, “Bums to the wall, Dom’s on the crawl,” according to court documents.

Some students told police that after being sent to his office for punishment, he would ask them to sit on his knee while he touched them inappropriately.

One victim told police he reported the abuse to his mother, who said: “You shouldn’t have been sent to his office in the first place. It’s your fault”.

In the District Court O’Sullivan pleaded guilty to twelve acts of indecent assault.

He will be sentenced on July 1.
