Defamed Online or on Social Media? Legal Action Can Stop It.

Yes. Australian defamation law applies to all forms of publication, including social media posts, online reviews, comments, videos, and other digital content. The same elements that apply to traditional defamation — publication to a third party, identification of the plaintiff, and serious harm to reputation — apply equally to online content. A social media post published in Australia or accessible to Australian audiences can give rise to a defamation claim under Australian law. The identity of the poster and their location may affect the practical steps involved, but does not negate the underlying legal right to sue.

If the person who published defamatory content about you is anonymous, Australian courts can grant preliminary discovery orders requiring a platform or internet service provider to disclose the identity of the poster. These orders are available before a defamation claim is formally commenced and require you to demonstrate that you have a reasonable cause of action against an unidentified person and that disclosure is necessary to enable you to identify and pursue them. Most major social media platforms and Google maintain Australian operations and can be served with Australian court orders. A lawyer can advise on the process and prospects in your case.

Yes. Urgent injunctions requiring removal of defamatory content can be sought from Australian courts where the plaintiff can show a serious question to be tried, that the balance of convenience favours removal, and that damages would be an insufficient remedy. Courts will balance freedom of speech considerations against the harm caused by ongoing publication. In some cases, a legal letter to the publisher or platform — particularly when supported by a clear legal argument — can achieve voluntary removal without requiring a court order. A lawyer can advise on the most effective and quickest pathway in your circumstances.

In Defteros v Google LLC [2022] HCA 33, the High Court of Australia held that Google was not the publisher of third-party hyperlinked content and was not liable for defamation in that case. The decision has implications for the liability of search engines and online platforms for third-party content. However, platforms can still be liable as publishers of content they host and fail to remove after being notified of its defamatory nature, and individual posters remain liable for their own publications. The law in this area continues to develop, and a lawyer can advise on the current state of platform liability relevant to your matter.

The eSafety Commissioner has powers under the Online Safety Act 2021 (Cth) to require removal of "cyber abuse" content targeted at adults — material that a reasonable person would consider seriously harmful. This is a broader concept than defamation and does not require the content to be false. Complaints can be lodged with the eSafety Commissioner if the relevant platform does not remove content after it is reported. The ACMA regulates some online content, particularly content hosted on Australian-registered platforms. These regulatory pathways can be pursued in parallel with defamation proceedings and may achieve content removal without litigation.

Defamation litigation in Australia can be expensive and time-consuming if it proceeds to trial. Legal costs for contested defamation matters can reach tens of thousands to hundreds of thousands of dollars, depending on complexity. However, many online defamation matters resolve well before trial — often through letters from lawyers, content removal, and negotiated compensation. The viability of pursuing a claim depends on the seriousness of the harm, the prospects of identifying and pursuing the defendant, and the likely damages. A lawyer can give you a realistic assessment of costs and likely outcomes before you commit to action.
