A competitor writes a fake review accusing your business of fraud. A disgruntled former employee posts a fabricated story about unsafe practices. A customer who never visited your premises leaves a one-star review claiming your staff were abusive.
These aren't just annoying — they may be defamatory. And in Australia, defamation law gives you real, enforceable rights. But acting on those rights requires understanding the legal framework, the thresholds, and the practical steps that actually produce results.
What Is Defamation in Australia?
Defamation in Australia is governed by the Defamation Act 2005 (uniform legislation across all states and territories, with amendments that took effect in 2021-2023). A review is potentially defamatory if it meets two core tests:
Test 1: Does it lower your reputation?
The publication must be capable of lowering the business's (or an individual's) reputation in the eyes of reasonable members of society. This is an objective test — it doesn't matter whether you feel defamed. The question is whether a reasonable person reading the review would think less of your business as a result.
Reviews that accuse a business of:
- Fraud, dishonesty, or criminal conduct
- Professional incompetence or negligence
- Unsafe, unhygienic, or illegal practices
- Discrimination or harassment
- Financial insolvency or non-payment of debts
...are all potentially defamatory on their face, because they go to the core of a business's professional reputation.
Test 2: Is there serious harm?
Under the 2021 amendments (which introduced a "serious harm" threshold), the defamation must have caused or be likely to cause serious harm to reputation. This is a higher bar than simply being "bad for business." Courts look at factors including the reach of the publication, the gravity of the allegations, and the actual or probable impact on the business.
A single one-star review that says "the food was cold" is almost certainly not defamatory — it's a genuine opinion, even if inaccurate. A review that says "this restaurant gave me food poisoning and they know their kitchen is unsafe" is potentially defamatory, because it makes a specific factual allegation of dangerous conduct that could seriously harm the business.
The Key Distinction: Fact vs Opinion
This is the most important concept in review defamation, and it's where most business owners misunderstand their rights.
Statements of fact can be defamatory. If a review states as fact something that is untrue and damaging — "they overcharged me by $500" when no such overcharge occurred — that can be defamatory.
Statements of opinion are generally protected. If a reviewer says "I thought the service was terrible" — even if you disagree — that's an opinion, and opinions are not typically defamatory, even when they're negative. The honest opinion defence is one of the strongest defences in defamation law.
The problem area is mixed reviews — reviews that combine factual claims with opinion. "They overcharged me (factual claim) and the service was the worst I've experienced (opinion)." In these cases, the factual elements may be actionable even if the opinion elements are not.
of potentially defamatory reviews: those containing false statements of fact (actionable) and those containing unprotected factual assertions disguised as opinion (also actionable). Pure negative opinions are not defamatory.
Who Can Sue? The Small Business Question
Under the 2021 amendments to the Defamation Act, corporations with 10 or more employees generally cannot sue for defamation. This was a major change that excluded most medium-to-large companies from defamation law.
However, small businesses with fewer than 10 employees can still sue for defamation. This includes sole traders, partnerships, and small companies — which covers the vast majority of businesses that are typically targeted by fake reviews.
Additionally, even if your business itself doesn't qualify, individuals associated with the business can sue in their personal capacity if they're specifically named or identified in the review. If a fake review names the business owner personally and makes defamatory claims about them, the owner can pursue defamation action regardless of business size.
Other Legal Avenues Beyond Defamation
Defamation isn't the only legal tool available. Depending on the circumstances, fake reviews may also breach:
Australian Consumer Law (ACL)
Under the ACL, it's illegal to publish or facilitate false or misleading reviews. The Australian Competition and Consumer Commission (ACCC) has taken enforcement action against businesses that post fake reviews — both positive (about themselves) and negative (about competitors). If a competitor is posting fake negative reviews about your business, this may constitute misleading or deceptive conduct under section 18 of the ACL, or unconscionable conduct under section 21.
Intentional Interference with Economic Relations
If someone deliberately posts fake reviews to damage your business — particularly a competitor — this may constitute the tort of intentional interference with economic relations (sometimes called "intentional infliction of economic harm"). This is a civil wrong that allows you to sue for damages.
Injurious Falsehood
Similar to defamation but with additional requirements, injurious falsehood covers false statements made maliciously that cause actual financial damage. It requires proof of malice and actual damage, making it harder to establish than defamation, but it can apply in situations where defamation doesn't (e.g., for larger corporations).
The Practical Steps: What Actually Works
Understanding the law is one thing. Getting results is another. Here's the practical sequence that produces outcomes:
Step 1: Document Everything Immediately
Before the review gets edited or removed, screenshot it. Capture:
- The full review text and reviewer name
- The date and time of the review
- The reviewer's profile (other reviews, account creation date)
- Any responses or engagement on the review
- Your business records showing the reviewer was never a customer (if applicable)
Step 2: Respond Professionally
See our guide on how to respond to negative reviews for templates. The key principle: respond factually, professionally, and in a way that documents the issue without escalating it. If you have no record of the customer, say so.
Step 3: Flag and Escalate Through Google
Follow the systematic flagging and escalation process in our complete removal playbook. This is the fastest and cheapest path to removal and resolves the majority of cases.
Step 4: Issue a Concerns Notice (Formal Legal Step)
If Google doesn't remove the review and you believe it's defamatory, the next formal step under the Defamation Act is a Concerns Notice (previously called a "concerns notice" under the 2005 Act, updated by the 2021 amendments). This is a formal written notice that:
- Identifies the defamatory content
- Explains why it's defamatory
- Specifies the harm caused
- Demands specific remedial action (e.g., removal, apology, retraction)
A Concerns Notice from a legal professional carries significantly more weight than one from a business owner. It signals that you're serious and prepared to escalate. In many cases, the threat of formal legal proceedings is enough to prompt removal — either by the reviewer or by Google's legal team.
This is a core part of what Bad Review Busters does. Our $199 success-fee service includes the formal letter process — we work with legal professionals to issue formal correspondence that prompts action. You only pay if the review is actually removed.
Step 5: Court Proceedings (Last Resort)
If all else fails, defamation proceedings can be filed in an Australian court. This is expensive, time-consuming, and should only be pursued for serious cases involving significant harm. Most review defamation disputes are resolved at Step 3 or Step 4 — court is the exception, not the rule.
Working with Google's Legal Removal Process
Google has a separate legal removal process that's distinct from its standard content policy flagging. If you have a defamation case, you can submit a legal removal request through Google's Legal Help Centre.
This process requires:
- Identification of the specific content
- A clear explanation of the legal basis for removal (e.g., defamation under Australian law)
- Supporting documentation (e.g., a Concerns Notice or court order)
Google's legal team reviews these requests separately from standard content moderation. They don't adjudicate defamation — they remove content when there's a clear legal basis and supporting documentation. A well-documented request with formal legal correspondence has a significantly higher success rate than a standard flag.
Our success fee covers the formal letter process, documentation, and escalation through Google's legal removal channels. No removal, no fee.
Common Defamation Defences (and Why They Usually Don't Apply to Fake Reviews)
If you're considering defamation action, it's worth knowing the defences a reviewer might raise — and why they often don't apply to genuinely fake reviews:
- Truth/Justification: The reviewer claims the content is true. If you can demonstrate the factual claims are false (e.g., you have no record of the customer), this defence fails.
- Honest Opinion: The reviewer claims it's just their opinion. If the review contains false factual assertions, this defence doesn't protect those factual claims.
- Context: The reviewer claims the review is part of a broader context that changes its meaning. Rarely applicable to standalone reviews.
- Triviality: The reviewer claims the harm is trivial. If the review has caused actual business damage, this defence fails.
The key point: genuine fake reviews have weak defences. If the reviewer was never a customer and the factual claims are fabricated, most defences collapse. The challenge is usually identifying the anonymous reviewer, not winning the legal argument.
The Defamation Action Plan: A Summary
- Screenshot and document the review immediately
- Respond professionally — state facts, invite offline contact
- Flag through Google — standard content policy process
- Escalate through Google Business support — with evidence
- Issue a formal Concerns Notice — via legal professionals
- Submit Google legal removal request — with supporting documentation
- File court proceedings — only for serious cases with significant harm
Steps 1-4 are free and resolve the majority of cases. Step 5 is where Bad Review Busters comes in — our $199 success fee covers the formal letter and escalation process. Steps 6-7 are for serious cases that require legal proceedings.
The Bottom Line
Defamation law in Australia gives businesses real protection against fake and malicious reviews. But the law is only useful if you know how to use it. The businesses that succeed are the ones that document thoroughly, escalate systematically, and know when to bring in professional help.
You don't need to go to court to win. In most cases, the credible threat of legal action — backed by documentation and a formal letter — is enough. That's exactly what we do.
The best time to document a defamatory review was the moment it appeared. The second best time is now. Screenshot everything before it disappears — or before you need it.
