An elite Melbourne school will be investigated over its management of child abuse risks, after damning revelations this week.

ABC’s Four Corners this week exposed reports that a long-time volunteer athletics coach at St Kevin's College in Toorak was convicted of grooming a then 15-year-old student at the elite all-boys school in 2015.

The school’s headmaster and dean of sport both provided references for convicted sex offender Peter Kehoe, but did not support the victim of his grooming.

Headmaster Stephen Russell resigned and dean of sport Luke Travers was stood down this week. The deputy principal, Janet Canny, has been asked by the school's governing body to step aside.

St Kevin's has now confirmed that two more teachers are being investigated over abuse allegations too.

Victoria’s Education Minister James Merlino now says the Victorian Registration & Qualifications Authority (VRQA) has advised St Kevin’s College and the school's owner, Edmund Rice Education Australia, that it will review the school's management of child abuse risks.

The school says it will cooperate with the investigation.
