Unknown controllers of an Instagram account placing the teenage girls into categories ranging from "abduction material" and "one night stand" to "average" and "unrapeable".
The girls pictured in the Instagram story were all students from Foxwell State Secondary College in Coomera.
Parents of the children were notified by the school on Wednesday and Queensland Police launched an investigation.
"I was really emotional, you see it happen to other people and you think no way is this going to happen to your kids," one mother told 9News.
"I'd like to see these people, the kids that are doing it thinking it's a bit of fun, to be held accountable."
The Department of Education has labelled the posts as vile and launched a full investigation into the incident.
The department said any state school student found responsible would be held accountable for their actions.
