Landmark Cases & Results

Federal Court of Australia
Singh v Singh [2025] FCA 1531
Federal Court Serious Harm Threshold Stage 2 Reforms Successful

Mark Stanarevic successfully represented the applicant in this significant Federal Court defamation proceeding before Owens J. The case established important principles regarding the serious harm threshold under the 2021 Stage 2 reforms.

The Court held that a subsequent, more authoritative publication can intensify and lend credibility to earlier anonymous allegations — independently satisfying the serious harm element. The Dingle principle was confirmed as highly fact-dependent and more limited than previously assumed.

This landmark decision clarified how Australian courts approach competing causes of reputational harm and the interaction between multiple defamatory publications.

Federal Court of Australia
Google Review Identity Case [2020]
Federal Court Google Reviews Precedent-Setting

In a groundbreaking decision that attracted international media coverage including the BBC and New York Times, Mark Stanarevic secured Federal Court orders compelling Google to reveal the identity of an anonymous reviewer who had posted a defamatory one-star review. This case established that courts can and will pierce online anonymity to protect reputations.

NSW Supreme Court
Portelli v Classic Cars [2023]
NSW Supreme Court Successful Defence

Matrix Legal successfully defended Adrian Portelli's company in proceedings brought in the NSW Supreme Court Equity Division, securing a complete dismissal of the claims. A comprehensive victory achieved through rigorous pre-trial strategy.

County Court of Victoria
Facebook Defamation Settlement
Social Media Settlement Damages Recovered

Secured a significant damages settlement for clients defamed through Facebook posts, achieving vindication and compensation without the need for a full trial — demonstrating the value of expert pre-trial strategy.

Most of our matters resolve favourably before trial through strategic negotiation and pre-litigation action. The cases above represent a selection of our publicly reported matters.

Understanding Defamation Law in Australia

A comprehensive guide to Australian defamation law prepared by Mark Stanarevic — covering legislation, case law, and practical guidance.

Defamation occurs when a statement is communicated to a third party that damages someone's reputation. Under the Defamation Act 2005, uniform legislation applies across all Australian states and territories.

A defamation claim requires three elements: (1) the material was published to at least one third party, (2) the material identifies the plaintiff, and (3) the material is defamatory — meaning it would lower the plaintiff's reputation in the estimation of reasonable members of the community.

The distinction between libel (written) and slander (spoken) was abolished in 2006 under uniform legislation. All forms of publication — written, spoken, broadcast, or online — are now governed by the same framework.

Since the Stage 2 defamation reforms, plaintiffs must establish that the publication has caused, or is likely to cause, serious harm to their reputation (section 10A, Defamation Act 2005). For corporations with fewer than 10 employees and not-for-profits, serious financial loss must be demonstrated.

This threshold is determined by the court as a preliminary question before the matter proceeds to trial. It functions as a filter against trivial claims while preserving access to justice for genuine cases.

As demonstrated in Singh v Singh [2025] FCA 1531, causation of serious harm is assessed on a case-by-case basis. The Federal Court confirmed that a subsequent, more authoritative publication can intensify and lend credibility to earlier anonymous allegations — independently satisfying the serious harm element.

Australian defamation law recognises a number of complete defences:

The previous triviality defence was effectively replaced by the serious harm threshold introduced in the 2021 Stage 2 reforms.

Australian defamation law provides for several categories of damages:

In Rush v Nationwide News [2019], the Federal Court awarded $850,000 in general damages plus $1.92 million in special damages — one of the largest defamation awards in Australian history. This illustrates that the statutory cap on general damages does not limit total recovery.

A defamation matter typically follows this process:

Time Limit: You must commence proceedings within one year of publication. Extensions up to three years are available only in exceptional circumstances. Act promptly.

Online defamation has become the primary battleground in modern reputation law. Key issues include:

A concerns notice is a formal pre-litigation notice required under the Defamation Act 2005 before you can commence defamation proceedings in most Australian jurisdictions.

A valid concerns notice must:

Upon receiving a concerns notice, the defendant has 14 days (in some jurisdictions, 28 days) to respond with an offer to make amends. A genuine offer to make amends — which may include an apology, a correction, or damages — can be a complete defence to the proceedings if the plaintiff unreasonably rejects it.

Strategic considerations: A well-drafted concerns notice sets the tone for the litigation and can be a powerful tool in achieving early resolution. Poorly drafted notices may be defective and expose the plaintiff to costs. Expert advice at this stage is critical.

Defamation is not limited to individuals. Businesses face specific challenges in the digital era:

Frequently Asked Questions — Defamation Law

Our defamation cases are run on a fee-for-service basis. We provide a detailed costs agreement before engagement outlining all fees and anticipated costs. We do not operate on contingency ('no win, no fee') as this is not permitted for defamation matters in Australia. An initial assessment helps determine the scope and likely costs of your matter.

You must commence defamation proceedings within one year of the date of publication. In limited circumstances, courts may grant an extension up to three years, but this is exceptional. Time is critical — contact a defamation lawyer immediately if you believe you have been defamed.

Yes. Social media posts on Facebook, Instagram, Twitter/X, TikTok, LinkedIn, and other platforms can be defamatory. Following the High Court's decision in Fairfax Media v Voller [2021] HCA 27, page administrators may also be liable for third-party comments. We have extensive experience in social media defamation matters.

The statutory cap on general damages (non-economic loss) is currently $500,000, indexed annually. This cap can be exceeded where aggravated damages are warranted. Special damages for proven financial loss are uncapped. In Rush v Nationwide News [2019], the Federal Court awarded $850,000 in general damages plus $1.92 million in special damages.

A concerns notice is a formal pre-litigation notice required under the Defamation Act 2005 before you can commence defamation proceedings. It must identify the defamatory material, the imputations conveyed, and the harm caused. The recipient has 14–28 days (depending on jurisdiction) to respond with an offer to make amends.

You can take legal action regarding defamatory Google reviews. Mark Stanarevic secured landmark Federal Court orders compelling Google to reveal the identity of an anonymous reviewer. We can assist with identifying anonymous reviewers, obtaining court orders for content removal, and pursuing damages claims.

Since the 2021 Stage 2 reforms, you must prove that the defamatory publication has caused, or is likely to cause, serious harm to your reputation. This threshold filters out trivial claims and is determined by the court as a preliminary question before the matter proceeds to trial.

Only corporations with fewer than 10 employees and not-for-profit organisations can sue for defamation in Australia. They must demonstrate serious financial loss rather than just reputational harm. Larger corporations cannot bring defamation claims but may have other legal remedies including injunctions and misleading conduct claims under the Australian Consumer Law.

Key defences include truth/justification, honest opinion, qualified privilege, public interest (introduced 2021), absolute privilege, innocent dissemination, and contextual truth. The previous defence of triviality was abolished with the introduction of the serious harm threshold under the Stage 2 reforms.

Defamation law is highly specialised with complex procedural requirements, strict time limits, and nuanced legal principles. A general practitioner is unlikely to have the depth of experience needed. Matrix Legal handles defamation matters exclusively, giving our clients the advantage of specialist expertise refined over hundreds of cases.

Historically, libel referred to written defamation and slander to spoken defamation. The distinction was abolished in Australia in 2006 under the uniform Defamation Act 2005. All forms of defamation — whether written, spoken, broadcast, or published online — are now governed by the same legislation.

Generally, defamation proceedings are public. However, in some circumstances, courts may grant suppression orders or pseudonym orders to protect a party's identity. This is at the court's discretion and requires compelling reasons — for example, where the proceedings themselves might republish the very imputations complained of, or where there are safety concerns.
