A paedophile headmaster who was allowed to stay on at an Ipswich school after molesting a pupil, also took schoolboys out in his car during classes to sexually assault them, according to former students.

The men have revealed Br Dominic O’Sullivan was known to use various ruses to get schoolboys to go out in his car while he was principal of St Peter Claver College at Riverview from 1991 to 1996.

He would then drive the boys to sparsely populated areas in the suburb and try to molest them in his car.

On one occasion, he lured a male student into his car after claiming he needed the boy's help to find a runaway schoolboy, according to one former student who has asked not to be named.

THE LATEST revelations about Br Dominic taking children out of the school has raised questions about whether teachers or Catholic education officials had knowledge of his routine highly inappropriate interactions with students but did not intervene.

Last month the Guardian & Tribune detailed how Br Dominic was posted to the Ipswich school despite previous complaints about his paedophile behaviour in New South Wales in the 1970s and 1980s.

The newspaper also revealed how he was allowed to stay on in the Ipswich job in mid 1996 despite a Year 9 boy complaining he had been molested by the Brother. 

The student later dropped the complaint on the urging of his father who had been reassured by a teacher that Br Dominic was "not that type of person" and "just loved kids".

Brisbane Catholic Education (BCE) responded by allowing Br Dominic to remain in the job on the condition that he be "hands-off" with students, according to evidence presented to the Royal Commission into child abuse.

The Guardian & Tribune has since uncovered more than a dozen other male former students who say Br Dominic molested or inappropriately touched them, some when they were particularly vulnerable in the school's sick bay.

Some of the abuse took place well after the so-called "hands-off" policy was imposed on the Brother by officials.

The incident involving boys being taken out in his car in the mid 1990s is the first time abuse by the Brother has been reported to have happened outside the school grounds.

Most of his victims have asked not to be named however a St Peter Claver College facebook page for past students has featured accounts by named students angrily recounting how they were molested by Brother Dominic who was also known as Darcy John O'Sullivan.

Some victims have expressed disappointment to the newspaper that the school or BCE have not moved to mount an internal investigation and launch a major public campaign to offer assistance and to call for the police to investigate.

Last month, the school's current principal Terry Finan sent a note to all students reiterating that BCE had only been aware of one complaint during the Brother's time at the college and this had been referred to the police.

This complaint is believed to be the incident reported in 1996 involving a Year 9 boy which saw Br Dominic allowed to stay on at the school and the complaint later dropped.

Mr Finan urged anyone in the wider St Peter Claver College community who had knowledge of Br Dominic's inappropriate conduct to contact Brisbane Catholic Education or the police.

Previously BCE has admitted it did not stand down Br Dominic from his job after the complaint was made in 1996. But BCE has said such procedures were in keeping with the practices of the time.

Br Dominic is currently serving a lengthy jail term in NSW after being convicted for sexually assaulting more than a dozen schoolboys at schools at Casino and Newcastle in the 1970s and 1980s.
