The legal framework

Uniform defamation law was reformed in 2021 to introduce a serious harm element and a public interest defence. Australia is unusual in having a statutory eSafety Commissioner with power to order removal of cyberbullying material, image-based abuse and seriously harmful adult cyber-abuse.

In practice

Cost and coverage

eSafety complaints are free and fast; defamation litigation is costly.

Recent changes

The eSafety scheme is one of the few in the world where an individual can obtain a binding removal order without going to court.

Where to go

Worth knowing

Report to eSafety before considering legal action. Removal orders are usually obtained within days, and the evidence gathered supports any later claim. The concerns notice is now compulsory. It must set out the imputations and give the publisher a period to make an offer to make amends.
