More former students of one of Queensland's most prestigious schools have come forward with complaints of abuse at the hands of a disgraced paedophile former school counsellor.

As the Royal Commission into Institutional Responses to Child Sexual Abuse prepared to hear stories from abuse victims at both Brisbane Grammar School and St Paul's School over the next two weeks, BGS confirmed the inquiry had caused more victims to come out of the woodwork.

"The work of the Royal Commission has already encouraged others to come forward, and we are glad that they have now chosen to do so," the school posted to Facebook on Friday.

"The School has already started to engage with them, as we have done with many others to date, with a response built on a personal apology, counselling and mediation."
