A Brisbane principal has warned parents in a newsletter that derogatory emails sent to staff or abuse on social media will be reported to the Department of Education.

The Gap State High School (TGSHS) principal, Anne McLauchlan, says the online abuse has reached unacceptable levels and has urged parents to arrange a face-to-face appointment to discuss their issues.

Queensland Teachers’ Union president Kevin Bates says the abuse was prompted by a change in the school uniform policy, early last year.
