Schools will strengthen their anti-cyber bullying policies in 2012 following the suicide of a Melbourne teenager.

In addition, Victorian Principals Association has called for stronger repercussions for bullies – including legal action despite the often young age of perpetrators.

Earlier this month, a 14-year-old Taylors Lakes schoolgirl took her own life after being harassed online.

VPA deputy president Terry Condon said bullies needed to be held accountable. "There needs to be stronger litigation – that you can't write this sort of stuff and get away with it – no matter your age," he said.

"If kids have no fear, they'll keep doing it. They need to be aware that what they're doing is cruel and has long-lasting effects."

Mr Condon said most schools blocked Facebook and other social media, especially at primary schools.

South Morang St Francis of Assisi principal Dane Malone said his school's anti-cyber bullying policy was built into a larger student well-being policy.

"We have cyber bullying education, we have programs in our pastoral care, and we have a social skills program," he said.

"I suppose more and more you're hearing about cyber bullying being an issue, but the bullying side of things has always been there and we have always put a lot of work into ensuring the students are supported."

Parents Victoria president Sharron Healy said schools should develop policies in collaboration with parents, students and teachers.

"The policies developed should include a curriculum component for all children which addresses cyber-safety, bullying and etiquette," she said.

"There are far too many children falling prey to cyber bullying who end up taking their own lives. This cannot be allowed to continue."
