Running a small business means your reputation is one of your most valuable assets. A single post on social media, a Google review, a competitor’s “warning” email, or even a comment made in a group chat can spread quickly and cause real damage.
That’s where defamation law comes in. If you’ve ever wondered what defamation is in Australia, how it applies to businesses, and what you can do to protect your brand, this guide will walk you through the essentials in plain English.
We’ll cover what defamation is, what usually triggers disputes for businesses, the common defences, and practical steps you can take to reduce your risk (and respond confidently if you’re targeted).
What Is Defamation (And When Does It Apply To A Business)?
Defamation is generally when someone communicates something about a person or organisation that harms their reputation.
In practical terms, defamation law is about protecting reputation from damaging statements. For businesses, this can include statements that make customers, suppliers, or the public think less of your business, avoid you, or treat you with suspicion.
The Basic Building Blocks Of A Defamation Claim
While details vary depending on the circumstances (and the state or territory), defamation claims usually revolve around a few key questions:
- Was something “published”? Publication doesn’t just mean newspapers. It can include social media posts, online reviews, emails, letters, texts, websites, forum posts, and even spoken words in some contexts. “Published” generally means communicated to at least one other person.
- Was the business identified? The statement needs to be about your business (or clearly point to you), even if it doesn’t name you directly.
- Is the meaning defamatory? A statement may be defamatory if it would lower your reputation in the eyes of an ordinary reasonable person. For example, claiming your business is dishonest, unsafe, incompetent, or unethical can be defamatory depending on context.
Can A Business Sue For Defamation In Australia?
Sometimes, yes - but not always.
Under Australia’s defamation laws, most corporations can’t sue for defamation. In general, only an “excluded corporation” can bring a defamation claim (this usually means a smaller, non-public company - for example, one that employs fewer than 10 people and isn’t related to another corporation, or certain not-for-profit organisations).
This is why eligibility matters early: depending on your business structure and size, your company may not be able to sue in defamation even if the statements are damaging.
As a small business owner, it’s also worth knowing that even where “the business” can’t bring a claim, a person connected with the business (such as a founder or director) may be personally identified by the statement and may have options.
If you’re unsure whether your situation is defamation (or something else like misleading conduct), it’s worth getting tailored advice early, because how you respond can affect your legal position.
What About The “Serious Harm” Threshold?
In Australia, defamation law has moved toward focusing on real harm rather than technical arguments.
In many parts of Australia, a claimant may need to show the publication has caused, or is likely to cause, serious harm to their reputation. For businesses, “serious harm” can look like measurable reputational damage that impacts trade, bookings, or customer trust.
Exactly how the serious harm threshold applies can depend on the state or territory and when the relevant reforms commenced there. This can be important for small businesses dealing with online commentary - some negative feedback may be upsetting, but not legally actionable.
Common Defamation Risks For Small Businesses
Defamation disputes often arise in everyday business situations - especially where emotions run high and communication is fast.
Here are some of the most common risk areas we see for Australian businesses.
Online Reviews And Social Media Posts
Reviews are essential for growth, but they’re also one of the biggest reputational risk points.
Not every bad review is defamation. Customers are generally allowed to share opinions and negative experiences. However, reviews can cross the line where they:
- state “facts” that are untrue (for example, accusing you of criminal conduct, fraud, or unsafe practices without basis);
- identify staff members in a way that harms their reputation; or
- encourage others to avoid you based on allegations that aren’t supported.
If you’re dealing with suspicious or fabricated reviews, you may find it helpful to look at practical options for fake Google reviews - often the best outcome comes from a calm, structured approach rather than a public argument.
Competitor Comparisons And Marketing Claims
Many businesses compare themselves to competitors in marketing (“we’re better”, “we’re cheaper”, “we’re the most trusted”).
This is where you need to be careful. Saying something that damages a competitor’s reputation can raise defamation risk, and it may also overlap with Australian Consumer Law issues such as misleading or deceptive conduct if the claims aren’t accurate or are likely to mislead customers.
A good rule of thumb is: focus on your strengths, and avoid making “factual” allegations about a competitor unless you can clearly prove them and you have a strong reason to publish them.
Defamation risk can pop up when businesses:
- send internal emails about an employee’s conduct;
- share reasons for termination with others; or
- warn other businesses about a contractor or former team member.
Even if you feel justified, broad distribution of allegations can increase legal risk. When you need to manage performance, conduct, or exits, it’s usually safer to keep communications factual, limited to those who need to know, and consistent with your HR processes and contracts (for example, your Employment Contract terms and any workplace policies).
Customer Disputes That Escalate
When there’s a complaint about service quality, refunds, delivery delays, or cancellations, businesses sometimes respond publicly with “their side of the story.”
This can be a trap. Even if your customer is being unfair, responding with accusations (for example, “they’re a scammer” or “they’re lying”) can create defamation exposure.
In many cases, it’s safer to respond politely, offer a private channel to resolve the issue, and keep the details confidential unless you have strong legal reasons to say more.
What Defences Can Apply If Your Business Is Accused Of Defamation?
If someone threatens a defamation claim against your business, it doesn’t automatically mean you’ve done something wrong.
Defamation law includes a range of defences, and the right one depends heavily on the wording used, the context, and what evidence you have.
Truth (Justification)
If the defamatory imputations are substantially true, truth can be a complete defence in many situations.
From a business perspective, this is why documentation matters. If you need to make a serious allegation (for example, in a dispute with a supplier), you should be confident you can support it with evidence.
Honest Opinion
There is often a defence available where the statement is clearly an opinion (not presented as a fact), relates to a matter of public interest, and is based on proper material.
In practice, businesses often get into trouble where they present opinions as facts, or where the “opinion” is really an allegation (like “they steal money”) rather than a value judgment.
Qualified Privilege
Some communications may be protected where the recipient has an interest in receiving the information and the publisher acts reasonably in the circumstances.
This can arise in some business contexts (for example, certain complaint-handling scenarios). But it’s not a “free pass.” Over-sharing, exaggeration, or acting unreasonably can undermine the defence.
Public Interest
There can be protections for publishing material on matters of public interest where the publisher reasonably believed publishing was in the public interest.
For most small businesses, this defence is less commonly relied upon day-to-day, but it can be relevant where you’re speaking out on safety issues, scams, or broader community risks. The key is reasonableness and evidence.
Defamation issues online often involve multiple parties: the person who wrote the content, the platform that hosted it, and the business targeted by it.
Some parties may argue they were not the author and did not know (and could not reasonably have known) the content was defamatory. This is particularly relevant for intermediaries.
For your business, the practical takeaway is: if you’re dealing with defamatory content hosted on a page you control (like your own website or business social media), your response time and takedown processes matter.
How To Reduce Defamation Risk In Your Business Communications
The best defamation strategy is prevention: building communication habits and systems that reduce risk while still letting you run your business confidently.
Here are practical steps you can implement.
1. Separate Facts From Opinions (And Label Opinions Clearly)
If you’re making public statements (for example, responding to a customer complaint), be careful about stating allegations as facts.
Instead of “They’re lying,” stick to something like “We can’t find a record of this booking on our system - please contact us directly so we can investigate.”
2. Keep Complaints And Disputes As Private As Possible
It’s tempting to defend your business publicly. But the more you publish, the more risk you create.
Where appropriate:
- move conversations to private messages or email;
- limit internal distribution (only to team members who need to know); and
- avoid naming individuals unless necessary.
3. Put Clear Guardrails Around Marketing And Advertising
Defamation isn’t the only risk in marketing. Claims can also lead to consumer law issues, especially if comparisons aren’t accurate or are likely to mislead.
If your business is publishing bold claims, it helps to have your website content and disclaimers reviewed. Something as simple as an email disclaimer won’t “fix” defamation risk on its own, but good legal hygiene across communications can reduce misunderstandings and disputes.
Many defamation problems start with a well-meaning team member responding too quickly, too emotionally, or with too much detail.
Consider implementing a simple internal policy:
- who is allowed to respond publicly;
- what tone to use;
- what topics must be moved offline; and
- what statements are never acceptable (accusations of theft, fraud, criminal conduct, etc.).
5. Use Strong Contracts To Manage Disputes Before They Go Public
Clear customer terms can reduce the likelihood of disputes escalating to reputational warfare.
Depending on your business model, this might include Terms of Trade (especially if you sell B2B), or properly drafted consumer-facing terms and policies that set expectations early (payments, cancellations, delivery timeframes, complaint pathways).
What To Do If Someone Defames Your Business (Step By Step)
If you believe your business has been defamed, it’s completely normal to feel frustrated - especially if it’s public and impacting sales.
At the same time, your early actions matter. A rushed response can make things worse, even when you’re in the right.
Take screenshots, copy URLs, and note dates and times. If it’s a video or story post that may disappear, preserving evidence early is crucial.
If the content is likely to be edited or deleted, evidence can become a major issue later, so don’t delay this step.
2. Don’t Respond Emotionally Or Make Counter-Accusations
This is the hard part.
Responding publicly with aggressive accusations can create a new defamation risk (against you), and it can also entrench the other party’s position. In some cases, it can even amplify the defamatory content by drawing more attention to it.
3. Consider A Takedown Request (Where Appropriate)
If the content is on a platform that has reporting tools, you may be able to request removal, particularly if the post breaches platform rules (harassment, threats, privacy issues, etc.).
If the content is on a business page you control, remove it quickly while still preserving evidence.
Often, the most effective next step is a carefully drafted letter asking for removal, a retraction, and/or an apology.
Depending on the situation, this may be similar in tone and structure to a cease and desist letter - firm, clear, and focused on what you want done next.
The goal is usually to de-escalate while protecting your rights, rather than turning the dispute into a public fight.
5. Explore Settlement Options If It’s Commercially Sensible
Defamation disputes can become expensive and time-consuming. Even if you’re confident, it’s often worth considering commercial outcomes, such as a negotiated removal and a written undertaking not to republish.
Where parties reach agreement, a properly drafted Deed of Settlement can help document the outcome and reduce the risk of the issue resurfacing later.
6. Get Legal Advice Early (Before The Situation Spreads)
It’s usually easier to resolve defamation issues early, before content goes viral or gets republished across multiple platforms.
Early advice can also help you work out whether defamation is the right legal lens - or whether the issue is better addressed through other options (for example, consumer law, contractual remedies, or platform-based takedowns).
