Parents should be aware that the Australian Government has created the Office of the eSafety Commissioner which is committed to helping young people have safe, positive experiences online and encouraging behavioural change, where a generation of Australian children act responsibly online—just as they would offline.
They provide online safety education for Australian children and young people, a complaints service for young Australians who experience serious cyberbullying, and address illegal online content through the Online Content Scheme.
For parental support and guidance in the area of Cybersafety you can visit their iParent support portal.
