Teenage school kids are fighting back against cyber-bullies through a new website.

Project Rockit is the brainchild of two Melbourne sisters, determined to end the cyber-bullying age.

Rosie and Lucy Thomas have worked with more than 30,000 school students during a series of workshops to tackle the issue of bullying in all forms.

The program, supported by Richmond AFL star Daniel Jackson, has been so successful it is now available online as P-Rock, and teenagers at McKinnon Secondary College can't get enough of it.

"It tells you how to sort things out, what to do, what not to do," one student told Seven News reporter Margaret Dekker.

"I like how there's lots of interactive features on it, and it's not all reading through walls of text," another added.

Parents have also welcomed a new online tool, ProtectaChild, which allows them to monitor online networks.
