The Education Department confirmed it was made aware of a post containing inappropriate content relating to students on Wednesday.
“The school acted immediately to have the post removed and is working with impacted students and their families to offer ongoing support,” a spokesperson said in a statement.
A department probe indicated the post was not made by a member of the school community.
“Like all Queensland state schools, Foxwell State Secondary College takes the issue of bullying very seriously and is committed to ensuring the safety and wellbeing of every student,” the spokesperson said.
The department said it had a team that could be deployed to help the Coomera school with the “negative” and “harmful” behaviour.
“The team provides advice on reporting harmful content through social media platform tools, as well as working with stakeholders about the removal of inappropriate or extreme content,” the spokesperson said.
It is the second incident in Australia this month.
Three students were suspended at Yarra Valley Grammar School earlier in May over a spreadsheet ranking female peers.
It included the same category of “unrapeable” and others like “wifeys”, “cuties” and “object”.
The incident was reported to Victoria Police who said investigators would assess whether it was a “matter for police”.
Victorian Premier Jacinta Allan at the time labelled the behaviour disgusting.
“Respect for women has to be at the forefront of every classroom, every household, of every part of the community,” she said.
