Defamation Of A Company In Australia: Key Things To Know

Word travels fast online. A single damaging post, a harsh review from a competitor, or an inaccurate media mention can hurt your brand and bottom line overnight.

If you’re running a small business, it’s natural to ask: can a company sue for defamation in Australia? What should you do if someone is spreading false statements about your business? And how do you respond in a way that protects your reputation without making things worse?

In this guide, we’ll walk through how defamation works for Australian companies, what steps to take if your business is targeted, and smart risk management strategies to prevent issues in the first place. We’ll keep it practical and in plain English so you can take action with confidence.

Can A Company Be Defamed In Australia?

Yes, but there are important limits. Under Australia’s uniform defamation laws (adopted in each state and territory), most large corporations can’t sue for defamation. However, “excluded corporations” can.

What Is An “Excluded Corporation”?

An excluded corporation is a company that either:

• Employs fewer than 10 people (counting full-time equivalent staff), and is not related to another corporation; or
• Is a not‑for‑profit organisation.

If your business meets one of these criteria, you can bring a defamation claim in your company’s name.

The Serious Harm Threshold

Since 2021, plaintiffs must show the publication has caused, or is likely to cause, “serious harm” to reputation. For excluded corporations, that threshold is “serious financial loss.” This is a key filter designed to keep minor or trivial claims out of court.

What If You’re Not An Excluded Corporation?

Medium and large companies usually can’t sue for defamation. That doesn’t mean you’re powerless. Other legal avenues may be available, such as the tort of injurious falsehood (which has different elements, including proof of falsity, malice and actual financial loss) and remedies under the Australian Consumer Law for misleading statements made in trade or commerce.

If your issue involves online reviews, there are specific options to deal with fake Google reviews that sit alongside defamation law.

Common Defamation Scenarios For Small Businesses

We commonly see disputes in the following contexts:

• Competitor comparisons that cross the line into false statements about your products or integrity.
• Anonymous social media posts accusing your business of conduct that never occurred.
• Review‑bombing campaigns (often after a falling‑out or in response to enforcing your policies).
• Local media or community posts repeating unverified claims that damage your reputation.

Not every negative statement is defamatory. Opinions, fair comment based on proper material, and truthful statements are often protected. The key issue is whether a communicated statement (to at least one other person) carries a defamatory meaning about your business and causes serious harm (or serious financial loss for an excluded corporation).

What To Do If Someone Defames Your Business

It’s important to act calmly and methodically. The goal is to stop the harm quickly, preserve your evidence, and resolve the issue as efficiently as possible.

1) Capture Evidence And Assess The Risk

• Take dated screenshots and URLs of the publication (including comments, captions, reposts and any metrics visible).
• Note when you discovered it and any actual impact (lost accounts, cancellations, revenue drop, staff time diverted).
• Identify the author if possible. If the post is anonymous, the platform may still assist with removal where it breaches their policies.

Be careful about secretly recording calls when gathering evidence. If you need to record conversations, check the rules first and consider this primer on recording phone calls in Australia.

2) Consider A Proportionate Response

Sometimes, a polite request gets a quick correction or takedown. In other cases, you may need to escalate. Think about:

• Reaching out directly to correct a genuine misunderstanding.
• Using platform reporting tools (e.g. “defamation” or “false information” categories).
• Publishing a measured public response if appropriate (avoid inflaming the situation).

For structured online disputes, it’s worth following a clear playbook for handling Google review disputes to maximise your chance of removal or remedy.

3) Send A Concerns Notice (And/Or A Cease And Desist Letter)

In many states and territories, you must send a formal “concerns notice” and allow time for a response before filing defamation proceedings.

A well‑crafted letter should identify the statements, explain why they are defamatory, and request specific remedies (removal, correction, apology and/or compensation). If you’re not ready to pursue defamation, you can still send a professional cease and desist letter to put the other party on notice and prompt a resolution.

4) Explore Settlement

Many disputes resolve without going to court. Common settlement terms include a takedown, clarification or apology, and an agreed contribution to your costs. Where appropriate, the parties may sign a Deed of Release and Settlement to formalise the outcome and prevent the matter from reigniting.

5) Consider Legal Proceedings (If Needed)

Litigation is expensive and public, and there are strict time limits (generally 1 year from publication, subject to limited extensions). That said, court action can be appropriate for serious, ongoing attacks causing significant loss. A specialist lawyer can assess your prospects, defences you may face (such as truth, honest opinion or public interest) and the likely costs versus benefits.

Alternatives To Defamation: When The ACL Or Contracts Are Better Tools

Defamation isn’t the only pathway. Depending on the facts, you may have stronger or more practical avenues under contract or consumer law.

Misleading Or Deceptive Conduct (ACL)

If a competitor makes false claims about your business in trade or commerce, you may have remedies under section 18 of the Australian Consumer Law. This can be useful where the statements are promotional or comparative and aimed at customers. You can read more about your obligations and remedies around misleading or deceptive conduct and how the law approaches misleading conduct elements in practice.

Non‑Disparagement Obligations

If a dispute arises with a supplier, contractor or former staff member, check your contracts. Many businesses include non‑disparagement clauses in service agreements, settlement deeds or exits. While you can’t stop someone from reporting unlawful conduct, you can agree that parties won’t publicly criticise each other or harm reputations. Having clear terms in place makes enforcement much easier if problems arise later.

How To Reduce Your Defamation Risk (And Protect Your Brand)

Prevention is always cheaper than repair. A few practical steps can dramatically reduce exposure and help you control the narrative when issues arise.

Have Clear House Rules And Respond Consistently

• Publish fair, transparent customer service and complaints processes on your website.
• Train your team to escalate serious online allegations promptly (don’t argue in comments).
• Keep a central log of complaints, responses and outcomes to show reasonableness and good faith handling.

Monitor And Act On Reviews

Set up alerts for your business name and key personnel. Triage reviews into three buckets: genuine feedback (respond professionally), policy disputes (offer an offline resolution path), and false or malicious content (collect evidence and escalate for removal). Where appropriate, follow the structured steps that apply to fake reviews.

Protect Your Brand Assets

Your name and logo are core to your reputation. Consider registering your brand as a trade mark so you have clear rights against imitators and look‑alikes. Our team helps businesses register trade marks across classes that match your goods and services, which also strengthens your brand‑protection toolkit.

Use Smart Contract Clauses

• Include non‑disparagement and confidentiality clauses in key agreements (suppliers, contractors, settlement deeds and partnership exits).
• Make sure your contracts allow you to respond publicly to correct the record if the other side goes public first.
• If you run a platform or online store, your website Terms should prohibit defamatory content and allow you to remove harmful posts.

Know When To Ask For Help

If the stakes are high, it’s worth getting early advice. A short discussion can help you choose the right path (quiet removal, contractual enforcement, ACL action or a formal defamation concerns notice) and avoid missteps that escalate the situation.

Defences You Might Face (If You Sue)

Before sending demands, reality‑check your position. Common defences include:

• Truth (Justification): If the statement is substantially true, defamation won’t succeed.
• Honest Opinion: Opinions based on proper material, clearly presented as opinion, may be protected.
• Qualified Privilege: Certain communications (e.g. between interested parties) can be protected if reasonable.
• Public Interest: A publisher can defend material they reasonably believed was in the public interest.
• Innocent Dissemination: Intermediaries (like some platforms) may be protected in certain circumstances.

These defences are technical and fact‑specific. A strong concerns notice addresses them upfront by identifying errors, omissions and context.

When A Claim Is Made Against Your Business

Sometimes the shoe is on the other foot. A customer, former employee or competitor might accuse your business of defamation based on something you or your team posted.

• Pause and assess. Remove or edit the post if it’s inaccurate or unnecessarily harsh.
• Check your evidence. If the material is substantially true and you’ve presented it fairly (or it’s clearly opinion), you may have a defence.
• Respond professionally. Consider apologising for any misunderstanding or tone while reserving your rights on substance.
• Avoid threats. Over‑the‑top responses can backfire and extend the damage (the “Streisand effect”).

If the dispute escalates, a pragmatic resolution-sometimes documented in a short settlement deed-can protect both parties and get everyone back to business. Where appropriate, a deed can include mutual non‑disparagement and agreed wording for any public clarification, similar to a tailored Deed of Release and Settlement.

Key Takeaways

• Small businesses can sue for defamation if they’re “excluded corporations” (typically fewer than 10 employees), but they must show serious financial loss.
• Act quickly but calmly: preserve evidence, use platform processes, send a concerns notice or a professional cease and desist letter, and aim for a proportionate resolution.
• Sometimes defamation isn’t the best tool. Consider contract options (including non‑disparagement terms) and remedies for misleading or deceptive conduct.
• Have a playbook for online issues: monitor reviews, triage quickly, and follow structured steps for review disputes and fake reviews.
• Protect your brand early-register key trade marks and embed smart clauses in your contracts to reduce reputational risk.
• Get advice early if the stakes are high. A short chat can save time, costs and unnecessary escalation.
