Can You Be Sued For Leaving A Bad Review In Australia?

Online reviews can make or break a small business. A single post on Google or Facebook can influence a flood of customer decisions - and occasionally cause real damage if it’s false or unfair.

So it’s no surprise that one of the most common questions we hear is: can someone be sued for leaving a bad review? And from your perspective as a business owner, a more practical question follows - when (if ever) should you consider legal action, and what are your other options?

In this guide, we unpack how defamation works in Australia, what counts as a lawful opinion vs a defamatory statement, the role of consumer law in tackling fake reviews, and a step-by-step playbook for responding to harmful posts without making the situation worse.

Why This Question Matters To Small Businesses

Reviews are an important part of your brand’s reputation and sales funnel. Most small businesses rely on positive word of mouth, and a run of negative reviews (especially if false or malicious) can hurt revenue quickly.

At the same time, reviews are a legitimate way for customers to share experiences. Trying to silence feedback can backfire - legally and publicly. Getting the balance right means understanding your rights and the risks before you act.

Can A Business Sue Over A Bad Review In Australia?

Short answer: sometimes. In Australia, defamation law protects individuals and certain small businesses from false statements that cause serious harm to their reputation.

Here are the key points to know:

• Who can sue? Most companies cannot sue for defamation. However, an “excluded corporation” can - generally, a business that employs fewer than 10 people and is not related to another corporation. Many Australian small businesses fit this category.
• What must be shown? The review must contain a defamatory imputation (it lowers the business in the eyes of a reasonable person), it must be published to at least one other person (e.g. posted online), and it must identify your business. Since 2021 reforms, there is also a serious harm threshold in most states and territories. You’ll need to show the publication has caused, or is likely to cause, serious harm to your reputation (not just annoyance or embarrassment).
• Time limits apply. Defamation actions have strict limitation periods (often 1 year from publication, subject to limited extensions). Don’t sit on an issue for too long before getting advice.

If you meet these requirements, defamation can be a pathway - but it’s not the only one, and it’s not automatically the best first move. We cover alternatives and practical steps below.

What Counts As Defamatory Vs Just Negative Opinion?

Not every negative review is defamatory. In fact, plenty of harsh comments are protected by legal defences. Before taking action, consider whether the review may be covered by one of these common defences:

• Truth (Justification): If the review is substantially true, a defamation claim is unlikely to succeed - even if the tone is harsh.
• Honest Opinion: Reviews are often opinions based on stated facts (e.g. “We waited 45 minutes and my meal was cold - I wouldn’t go back”). If it’s genuinely an opinion, recognisable as comment rather than assertion of fact, and based on proper material, it may be protected.
• Public Interest: In some cases, a publisher may rely on a public interest defence, particularly for matters of broader significance. This is more common in media contexts than consumer reviews but still part of the legal landscape.

A few practical indicators help separate opinion from defamatory factual assertions:

• Specific allegations of unlawful, unethical or dangerous conduct (e.g. “they forged documents,” “they sell counterfeit products”) are more likely to be defamatory if false.
• Purely subjective statements (“not my style,” “too expensive,” “service wasn’t friendly”) are more likely to be opinion.
• Context matters. A short star rating with no explanation may carry less defamatory meaning than a detailed post alleging specific wrongdoing.

The bottom line: asking “is it false and harmful?” is a better starting point than “is it negative?”

Fake Reviews And The ACL: Alternatives To Defamation

Beyond defamation, Australia’s consumer laws offer tools to tackle reviews that are fake, misleading or deceptive. The Australian Consumer Law (ACL) prohibits conduct that misleads or deceives consumers, including the posting or commissioning of fake reviews. This applies whether the fake review harms a competitor or artificially inflates your own rating.

Key legal hooks include:

• Misleading or Deceptive Conduct: Posting fake content can breach section 18 of the Australian Consumer Law (ACL), which prohibits conduct that is likely to mislead or deceive. Our overview of the elements of misleading or deceptive conduct explains how regulators and courts assess these situations.
• False or Misleading Representations: Specific false claims about services or testimonials may also breach section 29 ACL, which targets false or misleading representations in trade or commerce.

If you’re dealing with clearly bogus content, you may have remedies under the ACL and platform policies (for example, Google’s prohibited and restricted content rules) without needing to start a defamation case. We’ve put together practical guides on addressing fake Google reviews and broader Google review disputes if you’re looking for quick, actionable steps.

Should Your Business Sue Over A Bad Review?

Lawsuits are an option - but they’re not a strategy. Before you consider defamation or any court process, weigh the commercial and PR realities.

Benefits Of Legal Action

• Serious harm or false allegations: If a review makes false claims that materially damage your business (e.g. alleging criminal conduct), urgent legal steps may be necessary to protect your brand and revenue.
• Deterrence: In limited cases, firm action can discourage further unlawful posts by the same person or others.

Risks And Downsides

• Costs and time: Defamation matters are complex and expensive. They can take many months (or longer) to resolve.
• Streisand effect: Suing can amplify attention to the review and trigger negative publicity if the community perceives it as heavy-handed.
• Defences may succeed: If the review is substantially true or opinion, a claim may fail - and you may be liable for the other side’s costs.
• Uncertain enforcement: If the reviewer is anonymous or overseas, even a win may not deliver practical outcomes quickly.

In many cases, a staged approach - starting with platform complaints, a calm response, or a tightly written cease and desist letter - is more effective and lower risk. Save litigation for the rare scenarios where the harm and legal merits justify it.

A Practical Playbook: How To Respond To Harmful Reviews

Here’s a step-by-step process we commonly recommend to small businesses. Tailor these to your circumstances and get advice if the matter is sensitive or escalating.

1) Screenshot And Record Evidence

• Take timestamped screenshots of the review, the reviewer profile and any related threads.
• Collect relevant internal records (jobs, emails, invoices) in case you need to demonstrate what actually happened.

2) Assess The Content Objectively

• Is the post an opinion or making specific factual allegations?
• Is it from a genuine customer or likely fake/competitor-generated?
• Has it caused, or is it likely to cause, serious harm to your reputation?

3) Choose A Proportionate First Response

• For fair but negative feedback: Consider a brief, professional reply acknowledging the concern and inviting the reviewer to continue the conversation offline. Many readers will judge your business by your response.
• For posts that breach platform policies: Flag and report the content using the platform’s removal tools, citing the relevant policy breach (fake content, hate speech, personal information, etc.).
• For potentially defamatory or harmful falsehoods: Seek advice quickly. A carefully drafted cease and desist letter often resolves issues without litigation.

4) Escalate Strategically

• If the platform declines removal and the content is unlawful, consider formal legal correspondence or a complaint grounded in defamation or the ACL (where fake or misleading reviews are involved).
• For larger or repeated campaigns against your business, build a central log of incidents to show pattern and harm.

5) Strengthen Your Long-Term Reputation

• Encourage genuine customers to leave honest feedback (never incentivise positive reviews in a way that could mislead).
• Improve internal processes to reduce common complaints surfacing in reviews.
• Adopt an internal playbook so your team responds consistently and constructively.

Can You Ban Customers From Leaving Bad Reviews In Your Contracts?

Be very careful here. Trying to gag customers is risky and can breach Australian law.

• Unfair contract terms: Clauses that restrict or penalise customers for leaving honest reviews may be unfair (and therefore void) under the ACL’s unfair contract terms regime for standard form consumer or small business contracts.
• Misleading conduct risks: Overly broad “no review” clauses, or threatening language around reviews, can themselves be misleading.
• Non-disparagement clauses: These are sometimes used in B2B or settlement contexts, but they must be carefully drafted. Our overview on Non-Disparagement Agreements explains common pitfalls and when they may be appropriate.

A better approach is to set clear, lawful ground rules in your customer-facing terms about respectful communication, complaint pathways and acceptable use. From there, use the legal avenues available if a customer crosses the line into false and harmful statements.

What About Anonymous Or Overseas Reviewers?

Platforms don’t always verify identities, which can make enforcement tricky. Still, you’re not powerless.

• Platform processes: Engage fully with the platform’s complaint system. Provide evidence that the review breaches policy (for example, it’s unrelated to a real transaction, or contains personal/health data).
• Pre-action steps: In serious cases, your lawyer may issue platform notices or seek orders to identify anonymous posters. This is a more intensive pathway and used sparingly.
• Commercial judgement: Sometimes the most effective move is to focus on new, genuine feedback and your public response, while quietly pursuing removal requests in the background.

Common Legal Pathways (Beyond Defamation)

While defamation gets the headlines, other causes of action may fit your situation better:

• Injurious Falsehood: Focuses on false statements published maliciously that cause you financial loss. The threshold is high and you need to prove actual damage.
• Misleading or Deceptive Conduct: When the issue is fake or manipulated reviews (e.g. reviews planted to harm a competitor, or paid testimonials presented as genuine), consider the ACL via section 18 and section 29.
• Breach of Confidence / Privacy themes: Posts that disclose confidential information or sensitive personal data may be removable under platform rules and other legal principles.

The right approach depends on content, context and your commercial priorities. It’s common to combine platform policy complaints with one or more legal arguments to increase removal prospects - while keeping litigation as a last resort.

Practical Do’s And Don’ts For Business Owners

• Do respond professionally and briefly when appropriate - prospective customers are also your audience.
• Do triage quickly: obvious fakes to platform reports; genuine complaints to customer care; harmful falsehoods to legal review.
• Do consider a phased approach, starting with the least escalatory step that can achieve the outcome you want.
• Don’t threaten legal action lightly - empty threats can be screenshot and shared widely.
• Don’t post or buy fake positive reviews to “balance out” negativity - that can breach the ACL and platform policies.
• Don’t include aggressive “no-review” clauses in your contracts - they often backfire and may be unenforceable.

When To Get Legal Help

Get advice early if a review:

• Alleges criminal, unethical or safety-related conduct that you dispute.
• Appears coordinated (e.g. multiple fake accounts posting in a short window).
• Is causing measurable revenue loss or contract cancellations.
• Contains private information, hate speech or other policy breaches the platform has not addressed.

A lawyer can help you assess defamation risk, prepare a proportionate response, and pursue removal through the platform and legal channels as needed. In many cases, a well-structured letter combined with targeted platform submissions achieves a quiet, quick resolution.

Key Takeaways

• In Australia, many small businesses can sue for defamation as “excluded corporations,” but you must show serious harm and weigh costs, risks and public perception.
• Not every negative review is defamatory - truth and honest opinion are strong defences, and context matters.
• When dealing with fake or manipulated reviews, the ACL’s rules against misleading or deceptive conduct and false representations can be powerful tools alongside platform policies.
• A staged response usually works best: gather evidence, assess the content, use platform removal options, consider a targeted cease and desist letter, and reserve litigation for exceptional cases.
• Avoid contract clauses that ban reviews - they can be unfair under the ACL. If using reputation clauses, draft narrow, lawful non-disparagement terms with care.
• Have an internal playbook for handling reviews and keep building genuine feedback - your professional response often speaks louder than the original post.
