Six-year-old boys at a prestigious Sydney school have been offered counselling after they became involved in "inappropriate sexualised behaviour".
Trinity Grammar School notified parents at the start of school holidays in December that a group of Year One boys had been getting naked and performing sex acts on each other in toilets and parts of the playground.
Headmaster Milton Cujes said the Department of Family and Community Services (FACS) was notified within hours of the Anglican school becoming aware of the situation after one of the boys spoke up.
But it was more than a week before parents of the boys involved were notified.
"FACS requested parents not be advised while they were investigating. FACS advised eight days later that the school could disclose events to parents of the boys directly involved," Mr Cujes told AAP in a statement on Saturday.
Once those parents were notified, the parents of all Year One boys were told of the incidents, which the school says FACS has identified as "sexualised behaviours" rather than "sexual assault".
A Trinity Grammar School staff member and the school's counselling department have also investigated the incidents.
Mr Cujes said the boys and their families have been offered counselling and other changes have been implemented.
Supervision policies have been changed and a rule allowing only one boy at a time to visit the toilets during class time has been introduced.
Infrastructure changes are also being considered.
Mr Cujes has not revealed how many boys were involved, but it's believed it could be up to nine, including one who has been withdrawn from the school by his parents.
Parents were told they would receive no refund of their $18,000 a year fees if they chose to remove their sons, according to News Corp.
FACS has been contacted for comment.
