Almost every Victorian secondary school has been faced with at least one incident involving graphic pictures of students being circulated on mobile phones or the internet, cyber safety experts and teachers have told Fairfax Media.
However, many schools have chosen to handle the matter internally and have not notified police - despite child pornography laws being broken.
Sexting is the act of people taking naked or revealing pictures of themselves and sending them to others via mobile phones or the internet.
Teachers have confirmed that in many cases schools prefer to use counsellors and cyber consultants to talk to the students and parents involved rather than contacting police.
When police are called in, lawyers say, there is no consistency in how they handle cases. In some instances teenagers have been warned by police, while others have been charged with child pornography offences.
