Online defamation and Google reviews in Australia

Online defamation in Australia is governed by the same state and territory Acts as print and broadcast. A Google review can be defamatory — but only if it carries a damaging, false meaning about an identifiable person, causes serious harm in most jurisdictions, and no defence applies.

What defamation means in a review

A review is defamatory if it conveys a meaning (an "imputation") that would tend to lower an identifiable person in the estimation of ordinary reasonable people, or cause them to be shunned, avoided or ridiculed. The plaintiff must prove three things at the outset: the matter was published to at least one person other than the plaintiff, it identifies the plaintiff (by name, photo or enough detail for people who know them), and it is defamatory in that sense.

Courts look at the natural and ordinary meaning a reasonable reader would take, including what is implied. "This clinic overcharged me" and "the dentist here is a fraud who invents treatments to rip off patients" are very different imputations, even if both come from an unhappy customer. The guide to what makes a Google review defamatory works through practical examples.

The serious harm element

Since the Stage 1 reforms, a plaintiff must also show that the publication has caused, or is likely to cause, serious harm to their reputation. For an excluded corporation, harm is not serious unless it has caused or is likely to cause serious financial loss. A judge can decide the issue early, before trial, and dismiss a claim that fails it.

Serious harm applies in New South Wales, Victoria, Queensland, South Australia and the ACT (from 1 July 2021), Tasmania (from 12 November 2021) and the Northern Territory (from 11 August 2025). It does not apply in Western Australia, which has not adopted the reforms and still uses the older triviality defence. The full timeline is on the Defamation Act 2005 page.

For a single review, serious harm is often the hardest element. Relevant factors can include how many people read it, the gravity of the imputation, whether it appears alongside the business's name in search results, and evidence of lost clients. A one-line insult on a profile with hundreds of positive reviews may not clear the bar; a detailed allegation of criminality on a small practice's profile may.

Who is a publisher?

Anyone who participates in communicating defamatory matter can be a publisher. The person who wrote the review is the primary publisher. The harder question has been whether platforms and page owners are publishers too.

In Fairfax Media Publications v Voller (2021), the High Court held that media companies that maintained public Facebook pages were publishers of third-party comments on their posts, because they had facilitated and encouraged those comments. In Google LLC v Defteros (2022), the High Court held that Google was not the publisher of a third-party article merely because a search result linked to it. Neither case was about Google reviews, and neither settles exactly where Google Maps sits.

The Stage 2 digital intermediary reforms

Stage 2 (Part A) responded to Voller. In jurisdictions that adopted it in full, it introduces:

Conditional exemptions for digital intermediaries providing caching, conduit or storage services, and for search engine providers, provided they did not initiate, select recipients for, encourage, edit or promote the matter. An exemption is to be decided early in proceedings.
A new defence for digital intermediaries where the intermediary had an easily accessible complaints mechanism and, within 7 days of receiving a written complaint, took access prevention steps that were reasonable (if any were available).
Court power to order non-party intermediaries to take access prevention steps, such as removing or blocking matter, even if the intermediary is not a party to the defamation case.

These have commenced in NSW and the ACT (1 July 2024), Victoria (11 September 2024), Tasmania (16 June 2025), the Northern Territory (11 August 2025) and Queensland (26 December 2025). South Australia adopted only the non-party order power (from 15 December 2025), so intermediary liability there remains governed by the common law. Western Australia has not adopted them. How the storage exemption and the new defence apply to a review platform has not yet been clearly tested in the courts.

For businesses, the practical consequence is that the reviewer remains the main legal target, while the platform's complaints mechanism becomes central. A well-documented complaint to Google is not just a request; in many jurisdictions it is the step that engages the intermediary's statutory position.

Defences that commonly arise for reviews

Justification (substantial truth). A defence if the defamatory imputations are substantially true. A reviewer who says "they charged me twice and refused a refund" and can prove it has a complete defence.
Contextual truth. Available where other, substantially true imputations in the same matter mean the remaining imputations do no further harm.
Honest opinion. Protects an expression of opinion, rather than a statement of fact, on a matter of public interest, based on proper material (material that is substantially true or otherwise protected). It fails if the opinion was not genuinely held. "Worst haircut I've ever had" is opinion; "the owner stole my deposit" is an allegation of fact.
Public interest. A defence (from Stage 1, not in WA) where the matter concerns an issue of public interest and the publisher reasonably believed publishing it was in the public interest. It was designed with journalism in mind, but is not limited to journalists.
Qualified privilege and innocent dissemination. Qualified privilege can apply where the recipient has an interest in the information and the publisher acted reasonably. Innocent dissemination protects subordinate distributors who did not know, and should not reasonably have known, the matter was defamatory.

The existence of these defences is why genuine negative opinion and true criticism are lawful. A business that reads a fair but painful review as defamation will usually waste money and attention. Our service for defamatory Google reviews only takes on reviews where there is a credible basis to say a line has been crossed.

Before any proceedings: concerns notices

In Stage 1 jurisdictions, an aggrieved person cannot start defamation proceedings unless they have first given a concerns notice that particularises the imputations, and the period for the publisher to make an offer to make amends (generally 28 days) has passed. The limitation period is generally one year from publication, extendable to a maximum of three years in limited circumstances. Both are covered on the Defamation Act 2005 page.

Where Google fits

Google offers two separate routes: flagging a review for breaching its content policy, and a legal removal request asserting that content is unlawful. They are assessed differently, and Google decides what to do in each case. See Google's legal removal route for how they differ and where court orders fit.

If you have a review that you believe makes false factual allegations about you or your business, request a free assessment below. We will tell you whether there is a credible case for a complaint — and if the review is lawful criticism, we will say so.

Frequently asked questions

Does a one-star rating with no text count as defamation?

Almost never. A bare star rating conveys little more than dissatisfaction and is hard to read as carrying a specific defamatory imputation. It may still breach Google policy if it is fake engagement, which is a separate question.

Can I be defamed if the review only names my business, not me?

Possibly, if people who know you would understand the review to be about you — for example, a sole practitioner or a small business where the owner is the obvious person being described. Identification is assessed from the perspective of readers with the relevant knowledge.

Does replying to a defamatory review hurt my legal position?

A calm, factual reply is generally sensible and can reduce the harm. An angry reply that repeats the allegations, or makes counter-allegations about the reviewer, can create problems of its own. Keep a copy of the original review before you respond.

Is a reviewer liable if they deleted the review after a week?

Deletion does not erase the earlier publication, but it can be highly relevant to serious harm and to damages. It also often makes formal action disproportionate.

Are the reforms retrospective?

Generally no. The Stage 1 and Stage 2 amendments apply to matter published after they commenced in the relevant jurisdiction, so the date of the review and the governing law both matter.
