Google review defamation: In business, your online reputation is everything. A single fake Google review can do serious damage. For business owners, particularly those running small operations, a false claim posted on online review platforms, alleging fraud, unsafe practices, or poor workmanship, can drive away potential customers before you even have the chance to respond.
The good news is that Australian defamation law provides protections for businesses in this situation. You may be able to have the review removed, identify the person who posted it, seek an apology and receive compensation for the harm caused.
This fact sheet explains when a Google review crosses the line into defamation, what legal options are available, how to identify anonymous reviewers, and what it realistically costs and takes to pursue a claim.
Key Takeaways
- Not every negative review is defamatory. The law distinguishes between false statements of fact and genuine opinion.
- Small businesses (fewer than 10 employees) can sue for defamation. Large companies generally cannot, subject to limited exceptions for certain not-for-profits.
- Courts can order Google to reveal the reviewer’s identity through a process called preliminary discovery.
- Google will not remove defamatory material without a court order confirming it is false and unlawful.
- Early legal advice helps you choose the right strategy, litigation is not always the most effective or cost-efficient path.
- O’Brien Criminal & Civil Solicitors have extensive experience in Google review defamation cases across Australia.
At a Glance: Is the Review Defamatory?
A review is likely defamatory if it:
- Contains a specific false allegation of fact (e.g., “This builder stole money from my deposit”)
- Was posted by someone with no genuine experience of your business
- Is part of a coordinated campaign of fake or misleading reviews
- Has caused measurable harm to your business, such as a significant drop in enquiries or sales
A review is likely NOT defamatory if it:
- Expresses a harsh but genuine opinion (e.g., “I thought the service was terrible”)
- Is negative but substantially true
- Reflects the reviewer’s honest assessment of a real experience
When Does a Google Review Become Defamatory?
Under Australian defamation law, a review becomes potentially actionable when it contains a false statement of fact presented as truth, rather than a genuine expression of opinion. Understanding this distinction is central to determining defamatory meaning in practice.
The key distinction is this:
- Statements of fact are specific allegations that can be proven true or false, for example, “This business failed to complete my roof repairs, leaving it leaking.” If false, this could give rise to defamatory imputations against the business.
- Expressions of opinion are subjective assessments, for example, “I think this business provides poor customer service.” If genuinely held, this is generally protected.
For a defamation claim to succeed, the business must show that the defamatory statement is false, that it was published to a third party (anyone who reads it counts), and that it causes or is likely to cause serious harm to the business’s reputation.
The Defamation Act 2005 (NSW) includes an honest opinion defence under section 31, which protects reviewers whose statements reflect genuinely held views based on their actual experience, even if those views are scathing. This means harsh but honest criticism is not defamation. What the law targets is falsehood.
On the flip side, businesses also have a potential cause of action in injurious falsehood, which applies where a person knowingly or recklessly publishes a false statement about a business that causes financial loss. While less commonly used than defamation, it can be a powerful tool in cases involving competitors who are deliberately posting fake reviews to damage a rival.
Who Can Sue for Google Review Defamation?
A significant and often overlooked feature of Australian defamation law is that small businesses can sue, but large companies cannot.
Under the uniform defamation legislation in force across all Australian states and territories, from New South Wales to South Australia, a corporation with fewer than 10 employees can bring a defamation action. This protection recognises that smaller businesses are more vulnerable to reputation damage and have fewer resources to absorb it.
Sole traders, partnerships, and small companies all fall within this category, provided they meet the employee threshold.
- The review contains false statements of fact (not opinion)
- Those statements were published to third parties
- The statements cause, or are likely to cause, serious harm to the business’s reputation
- The reviewer cannot establish a valid defence, such as honest opinion or truth
Google’s Review Removal Process
Before pursuing legal action, business owners have several practical options to try to have a false review removed.
Report to Google: Your Google Business Profile allows you to flag reviews that violate Google’s content policies. Reviews containing spam, harassment, hate speech, conflicts of interest, or external links may be removed. Google does not simply delete negative reviews because they are unflattering or the subject of a business complaint.
Respond to the review: Businesses can reply publicly to any review. A measured, professional response where you respond calmly to the specific allegations can reassure prospective customers and demonstrate that you take concerns seriously, even if the review itself is false. How you handle criticism in your search results matters because future customers will read your reply alongside the review.
Request removal via Google’s legal help portal: If a review meets Google’s policy violation criteria, businesses can report it through Google’s legal help page, providing detailed evidence of the breach.
Google generally will not remove a review purely on the basis that you allege it is defamatory. As a rule, it requires either a clear policy breach or a court order confirming the content is false and unlawful. Google does have a dedicated legal complaints form, but in practice it almost always needs one of those two grounds before acting on defamatory online reviews.
Court Orders and Injunctions
When informal steps fail, businesses can apply to the Federal Court of Australia for a preliminary injunction, a court order requiring the removal of defamatory content while proceedings are on foot.
To obtain a preliminary injunction, the business must satisfy three criteria from the leading case Australian Broadcasting Corporation v O’Neill (2006) 227 CLR 57:
- Serious question to be tried: There must be a credible defamation claim, with evidence that the review contains false statements of fact causing reputational harm.
- Inadequacy of damages: Monetary compensation alone must be shown to be an insufficient remedy, for example, where ongoing publication is causing continuing harm.
- Balance of convenience: The hardship to the business from continued publication must outweigh the reviewer’s interest in keeping the content up, having regard to the public interest in free expression.
Preliminary injunctions in defamation matters are granted sparingly. Courts give significant weight to freedom of expression, and injunctions are generally only ordered in exceptional circumstances. For example, where a defendant is conducting a clear campaign of false allegations or has indicated they will disregard court orders.
Identifying Anonymous Reviewers
Many defamatory reviews are posted anonymously or under a pseudonym. This doesn’t mean the reviewer is beyond reach.
Australian courts have developed a process called preliminary discovery, which allows a prospective applicant to compel a third party, including Google, to disclose the identity of an anonymous reviewer. The application is made under rule 7.22 of the Federal Court Rules 2011 (Cth).
A court may order preliminary discovery where:
- The applicant has a right to obtain relief against an unknown respondent
- The applicant cannot identify the reviewer without assistance
- Google holds information, such as account details, IP addresses, or registration data, that would identify the reviewer
In Kabbabe v Google LLC, the Federal Court ordered Google to disclose the identity of an anonymous reviewer. In Musicki v De Tonnerre [2023] FCA 222, a Melbourne vascular surgeon successfully unmasked a former student who had posted false reviews under a pseudonym. The court found that the reviews contained clearly defamatory allegations, and following disclosure, she obtained a defamation judgment of $75,000 in damages plus costs.
This process typically takes 3 to 6 months and costs approximately $3,000 to $8,000 in legal fees.
Removal Options Compared
| Method | Timeframe | Approximate Cost | Realistic Success Rate | Best Suited To |
| Report to Google | 1–3 weeks | Free | 10–15% | Reviews clearly violating Google policies (spam, hate speech) |
| Legal demand letter | 2–4 weeks | $800–$2,500 | 25–40% | Clearly false statements; reviewer is identifiable |
| Preliminary discovery | 3–6 months | $3,000–$8,000 | 60–75% | Anonymous reviewers; strong defamation case |
| Court injunction | 2–3 months | $5,000–$15,000+ | 5–10% | Serious ongoing harm; clear campaign of false allegations |
Real-World Scenarios
Scenario 1: The Competitor Posting False Reviews
A small plumbing business notices a sudden drop in leads and a decline in its online ratings. After investigating, the owner discovers three one-star Google reviews posted within a week, all alleging shoddy workmanship and unpaid refunds, none of which match any real customer interactions. With legal assistance, the business applies for preliminary discovery to identify the account holders. The reviews are traced to a competitor engaging in deceptive practices. Defamation proceedings follow.
Scenario 2: The Disgruntled Former Customer
A client disputes an invoice and, after failing to resolve it directly, posts a review under the business name claiming the company “defrauded” them and “threatened” them. Both allegations are false. The business sends a concerns notice, the formal step required under defamation law, followed by a legal letter requesting removal and a retraction. Faced with the prospect of litigation and the associated legal risks, the reviewer removes the post.
Scenario 3: The Anonymous Campaign
A small restaurant receives five fake reviews over two months, all from accounts with no review history and no verified visit. The owner reports the misleading reviews to Google, which removes two but leaves three, finding they do not breach its content policies on their face. The owner applies to the Federal Court for preliminary discovery. Google is ordered to provide the account information associated with the remaining reviews, which are traced to a single individual.
Litigation Strategy: Weighing Up Your Options
Defamation proceedings over a Google review are not always the right answer. Before committing to legal action, consider the following.
Legal Costs Are Real
Preliminary discovery or full defamation proceedings can cost between $8,000 and $30,000 or more in legal fees. Damages awards for a single defamatory review are often in the $5,000 to $20,000 range, meaning litigation may only be financially justified where the review has caused substantial, measurable harm.
Reputational Risk Cuts Both Ways
Litigation can attract media attention that amplifies the original review. That said, a successful outcome can rebuild customer confidence and demonstrate clearly that your business does not tolerate false accusations.
The Process Is Time Consuming
Defamation proceedings can take 12 to 24 months to resolve and demand management time and attention throughout.
Deterrence Has Real Value
A successful action against one reviewer can discourage others, which matters in cases where fake reviews appear to be coordinated.
The strongest candidates for litigation are business owners who can show measurable financial losses, cases involving multiple false reviews from the same source, and situations where informal removal attempts have already failed.
Honest Reviews and Consumer Protections
Australian law protects honest reviewers as well as businesses harmed by false ones.
The honest opinion defence under section 31 of the Defamation Act 2005 (NSW) protects statements that are expressions of genuine opinion rather than false statements of fact, based on proper material, and about a matter of public interest. A reviewer who honestly believes their criticism and can point to their actual experience is generally protected, even if their opinion is harsh.
The truth defence is equally straightforward: if a statement is substantially true, it cannot be defamatory, regardless of how damaging it is.
Under the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010 (Cth)), reviews must be genuine. Businesses cannot post fake positive reviews about themselves, and competitors cannot post coordinated false negative reviews. Both practices constitute misleading or deceptive conduct and can attract penalties of up to $50 million for serious violations. The ACCC has published guidance on what is and isn’t acceptable in the context of online reviews.
Frequently Asked Questions About Google Review Defamation
Can I sue for a negative Google review?
You can sue if the review contains false statements of fact that harm your reputation. A harsh but genuine opinion, however unflattering, is not defamatory. The difference matters: “This restaurant serves terrible food” is opinion and protected. “This restaurant gave me food poisoning and concealed it” (if false) is a statement of fact and potentially defamatory. You need to show the statement is false, published, and causes serious harm to your business.
How do I get a fake review removed from Google?
Start by reporting it through your Google Business Profile if it breaches Google’s content policies. Respond professionally to the review. If those steps don’t resolve it and the review is clearly false, a formal concerns notice followed by a legal letter is often the next step. If the reviewer is anonymous or refuses to act, preliminary discovery through the Federal Court can compel Google to disclose their identity. We recommend starting with free options and escalating only where the review is clearly false and causing real damage.
What is the honest opinion defence?
Under section 31 of the Defamation Act 2005, a statement is not defamatory if it is a genuine expression of opinion based on the reviewer’s actual experience, relates to a matter of public interest, and was honestly held at the time. This means reviewers can openly criticise a business without legal liability, provided they are expressing what they genuinely believe based on proper material, not fabricating facts.
Can I find out who left an anonymous review?
Yes, in appropriate cases. If you have solid grounds for a defamation claim, you can apply to the Federal Court under rule 7.22 of the Federal Court Rules 2011 (Cth) for preliminary discovery, compelling Google to disclose the reviewer’s name, address, IP address, and account information. The process takes roughly 3 to 6 months and costs $3,000 to $8,000 in legal fees. Cases like Musicki v De Tonnerre confirm the courts’ willingness to order disclosure where the defamation claim is credible.
Does a bad review have to cause financial loss to be actionable?
Not necessarily. The threshold is serious harm to reputation, which can exist even without immediate financial loss. That said, demonstrable financial loss, such as a drop in sales or lost contracts traceable to the false review, strengthens your case considerably and makes litigation more cost-effective.
Can competitors post fake reviews about my business?
No. Under the Australian Consumer Law, posting fake reviews or making misleading representations about a competitor constitutes misleading conduct. This includes coordinated campaigns of false negative reviews designed to damage a rival’s online ratings and Google Search visibility. The ACCC actively investigates these deceptive practices, and penalties can reach $50 million for serious violations.
Practical Steps If You’ve Been Hit by a Fake Review
Immediately:
- Screenshot the review and record the URL, reviewer name, and date
- Do not delete your own response if you’ve already replied
- Preserve any evidence linking the reviewer to a competitor, former employee, or disgruntled customer
Short-term:
- Report the review to Google through your My Business account
- Post a professional response addressing the specific allegations
- Contact a defamation lawyer to assess whether the review is likely actionable
If informal steps fail:
- Your lawyer can send a formal demand letter to the reviewer (if identifiable), seeking removal and a retraction
- If the reviewer is anonymous or refuses to comply, preliminary discovery proceedings can be commenced
- If the review continues to cause ongoing harm, an injunction application may be appropriate
