What is an Online Harm Notice?

Information on Online Harm Notices.

Last updated 30 June 2026

An Online Harm Notice is a formal notice that you, or your authorised representative, may send to an administrator or Online Service Provider to notify them that an online harm has occurred.

For the Online Harm Notice to be valid, the form used, particulars provided and manner of sending the Online Harm Notice must comply with requirements set out in law.

More information on the form and required particulars, and manner of sending the online harm notice can be found in the following pages.

If any of these requirements are not met, the Online Harm Notice would be invalid, and the administrator or online platform who receives the Online Harm Notice need not take any action on it.

After you or your authorised representative sends a valid Online Harm Notice, the recipient must assess whether the online harm has occurred. If it assesses that an online harm has occurred, the recipient must take reasonable steps to address the harm within a reasonable time.

Please note that an Online Harm Notice is distinct from the following reporting mechanisms:

  • Reports made to an online platform via its user reporting mechanism will not constitute a valid Online Harm Notice.

  • Reports to the OSC will not constitute a valid Online Harm Notice.

Please be warned that there are legal consequences for sending frivolous or false Online Harm Notices to administrators and online platforms.

To ensure that only genuine, properly documented cases trigger their duty to act, OSRAA provides that administrators and online platforms may hold those who send frivolous or false online harm notices liable in civil proceedings. Those who are found to have sent frivolous or false notices may be liable for the loss suffered as a result of such notices, including compensatory damages.
