Queensland police are investigating after year 10 boys were expelled from a Gold Coast school over "offensive" comments about female students.
The ABC has been told two male students were expelled and a third chose to leave Emmanuel College after the Gold Coast school launched an investigation when the online content was reported to staff two weeks ago.
The Carrara school emailed parents about the incident on Monday.
In a statement, Emmanuel College said students from at least two other Gold Coast schools were also involved "in online behaviour involving offensive and inappropriate comments about female students".
Police confirmed the incident was reported on October 22 and detectives had engaged with the schools involved to complete "preliminary inquiries".
Emmanuel College said counselling and support had been offered to all students and the Year 10 cohort had a group meeting.
"It is disheartening that this behaviour still occurs in our society and we are appalled that a small minority of boys consider it acceptable to view girls in this way," the school's statement said.
"We continuously educate our students about appropriate behaviour and provide them with the resources they need to make positive choices."
The Queensland Department of Education was contacted for comment.
Concerning behaviour
Professor of Social Work at Griffith University, Silke Meyer, said it wasn't the first time such behaviour had been reported in Australian schools this year.
The teen was not a student at the school.
Dr Meyer said despite expulsions and legal consequences, the incidents persisted and indicated a deeper cultural issue of male entitlement and the objectification of women.
"I think it's highly concerning," Dr Meyer said.
"This is young men that are dehumanising young women and treating them as sexual objects."
Dr Meyer said it emphasised a need for early education on gender, relationships and pornography.
She said it was also important to support victims and perpetrators to address the root causes of the behaviour.
