The O'Brien Advantage

We Act Fast

Social media content spreads in real time. Urgent applications for takedown orders, interlocutory injunctions, and platform notices require lawyers who understand the speed of the problem. We move quickly when speed is what your situation demands, advising on the fastest available path to limiting further harm.

Specialist Defamation Experience

Our defamation practice is led by Stewart O'Connell. We have acted in social media defamation matters across major platforms, from anonymous accounts on X (Twitter) to viral content on TikTok. Social media defamation has its own procedural and evidentiary challenges, we know how to navigate them.

Serious Harm Assessment

Since the 2021 reforms, and later amendments in 2024, a defamation claim in NSW generally requires proof that the publication caused, or is likely to cause, serious harm to your reputation. This threshold matters: not every hurtful post crosses it, and we will give you an honest assessment of whether yours does before advising you to proceed.

Flexible Payment Options

We offer flexible payment arrangements to ensure cost is not a barrier to accessing expert legal representation. Contact us to discuss your options during your free initial consultation.

TYPES OF SOCIAL MEDIA DEFAMATION WE HANDLE

Facebook Defamation

Posts, comments, and shares on personal profiles, business pages, and community groups can reach large, targeted audiences quickly. Facebook content is often directed at local businesses, tradespersons, or individuals within a specific community, making the reputational damage immediate and measurable. We advise on platform reporting, urgent content removal, and formal legal action where the publication meets the serious harm threshold.

Instagram Defamation

Stories, Reels, and caption posts on Instagram can be used to target individuals, particularly in business, creative, and professional contexts. Content that disappears after 24 hours is not beyond the reach of defamation law — screenshots and metadata can preserve the evidence.

TikTok Defamation

Video content on TikTok can go viral before any formal complaint is lodged. A short video making false statements about a person or business can accumulate hundreds of thousands of views within days. We advise on evidence preservation, urgent platform notices, and the legal avenues available when TikTok content causes serious reputational harm.

X (Formely Twitter) Defamation

Posts and threads on X (Twitter), including quote-posts and replies, are frequently used to make false factual statements about public figures, professionals, and businesses. The public and searchable nature of X content means defamatory material can appear prominently in Google search results for a person’s name. We act in matters involving individual users and, where appropriate, the platform itself under the digital intermediary reforms.

Anonymous Accounts and Fake Profiles

Many social media defamation matters involve anonymous or pseudonymous accounts. Identifying the person behind an anonymous account requires legal mechanisms including court orders compelling platforms to disclose subscriber information. We have experience obtaining preliminary discovery orders in this context.

The Defamation Claim Process

1. Free Initial Consultation

Contact our team for a free, confidential consultation. We will listen to what happened, explain whether you may have a claim, outline your legal options, and answer any questions you have about the process ahead.

2. Evidence Preservation and Investigation

Before content disappears, we move to preserve it. We capture screenshots, metadata, engagement data, and any other evidence that supports your claim. If the publisher is anonymous, we advise on the steps to identify them through the courts.

3. Concerns Notice and Pre-Litigation

We draft and serve a formal concerns notice on the publisher, setting out the defamatory imputations, the harm caused, and the remedy sought. Many matters resolve at this stage, through an apology, retraction, or negotiated settlement, without the need for proceedings.

4. Litigation or Resolution

If the matter does not resolve at the concerns notice stage, we advise on whether to proceed to court. We manage all aspects of the litigation, keep you informed throughout, and pursue the best available outcome for your reputation and your circumstances.

Remember: Defamation claims are legally complex and time-sensitive. Seeking expert advice as soon as possible gives you the best chance of securing justice and protecting your reputation.

Social Media Defamation: Frequently Asked Questions

Can you be sued for defamation over a social media post in NSW?

Yes. There is no exemption from defamation law for content published on social media. A post, comment, share, video, or review that conveys defamatory imputations, communicated to a third party, that causes serious harm to a person's reputation can give rise to a defamation claim in NSW. The Defamation Act 2005 (NSW) applies to online publication in the same way it applies to print or broadcast media.

What is the serious harm threshold in NSW defamation law?

Since the 2021 reforms to the Defamation Act 2005, a plaintiff in NSW must generally prove that the publication caused, or is likely to cause, serious harm to their reputation. For corporations trading for profit, a different threshold applies. This requirement was introduced to prevent claims over minor publications that do not cause meaningful damage. Whether a particular social media post meets the serious harm threshold depends on the nature of the imputations, the reach of the publication, and the plaintiff's circumstances. Our lawyers assess this at the outset of every matter.

Can I sue an anonymous person who defamed me online?

Yes, in many cases. Identifying an anonymous publisher typically requires a preliminary discovery order, which compels the social media platform to disclose the subscriber information linked to the account. Courts can order disclosure of identifying information in some cases. Once the publisher is identified, the claim can proceed in the normal way. The process takes time, which is another reason to act early.

Can the platform itself be liable for defamation?

In some circumstances, platform operators may be treated as publishers. The High Court in Fairfax Media Publications v Voller held that operators of public Facebook pages can be publishers of third-party comments in some circumstances. The 2024 reforms introduced new rules for digital intermediaries, including complaint and takedown processes. Whether a platform is liable in your matter depends on the specific facts. We advise on this as part of our initial assessment.

How long do I have to bring a social media defamation claim in NSW?

Defamation claims in NSW are generally subject to a one-year limitation period from publication under the Limitation Act 1969 (NSW).

Courts have a discretion to extend the limitation period in certain circumstances, but extensions are not routine. If you are aware of defamatory content that is more than a year old, contact us as soon as possible, there may still be options available, but they narrow with time.

What is a concerns notice and do I need to send one?

In most defamation claims, a concerns notice should be served before proceedings are started. A concerns notice should identify the publication, the imputations complained of, and the relief sought. The publisher may have an opportunity to make an offer of amends. A defective or missing concerns notice can delay or complicate proceedings. Our lawyers draft concerns notices that are legally precise and strategically calibrated.
