What Is Passing Off In Australia?

Your brand is one of your most valuable assets. If another business copies your name, logo, packaging or “look and feel” to ride on your reputation, it can quickly confuse customers and cost you sales.

That’s where the legal concept of “passing off” comes in. It’s a long-standing protection under Australian common law designed to stop businesses from misrepresenting that their goods or services are yours (or connected with you) when they’re not.

In this guide, we’ll explain what passing off is, how it differs from other laws like trade marks and the Australian Consumer Law, what you need to prove, and the practical steps to protect and enforce your brand.

Passing Off Explained: How It Protects Your Business Reputation

Passing off is about protecting the commercial value of your brand’s reputation (often called “goodwill”). If another trader misleads the public into thinking their products or services are yours, or that you endorse or are connected to them, that can amount to passing off.

Common examples include:

• Look‑alike packaging, colours or “get‑up” that makes shoppers think they’re buying your product.
• Using a business name, logo or tagline that’s deceptively similar to yours.
• False claims of endorsement, sponsorship, or an “official” relationship with your brand.
• Imitating your storefront design or website layout so customers assume a connection.
• Registering or using a confusing domain or social handle to funnel your customers.

Importantly, passing off focuses on whether the other business has made a misrepresentation likely to deceive the public and whether that misrepresentation causes (or is likely to cause) damage to your goodwill.

Passing Off vs Trade Marks vs Misleading Or Deceptive Conduct

It’s easy to mix up these concepts because they often arise in the same dispute. Here’s how they differ-and how they work together.

Trade Marks

A registered trade mark gives you a powerful, nationwide statutory right to stop others using the same or confusingly similar sign for the same or similar goods/services.

Passing off can protect unregistered brand elements too, but it’s generally easier and more efficient to enforce registered rights. Many businesses secure a strong foundation by applying to register your trade mark early and selecting the right trade mark classes for their products or services.

Australian Consumer Law (ACL)

The ACL includes a broad prohibition against misleading or deceptive conduct. Even if you don’t have a registered trade mark, conduct that confuses customers about source, affiliation or endorsement may breach section 18 of the ACL and specific false representation rules in section 29.

In practice, brand disputes often involve a combination of claims: trade mark infringement (if you have a registration), passing off (to protect goodwill) and ACL misleading or deceptive conduct. Running these claims together can increase your chances of a quick, effective remedy.

What Do You Need To Prove In A Passing Off Claim?

To succeed in passing off, you generally need to prove three elements:

1. Reputation/Goodwill: Your brand, get‑up or sign has a reputation among the relevant public in Australia.
2. Misrepresentation: The other business made a false representation (express or implied) that their goods/services are yours, are associated with you, or have your approval.
3. Damage (or a real likelihood of damage): The misrepresentation has caused, or is likely to cause, harm to your goodwill-such as lost sales, brand dilution or damage to your reputation.

Reputation/Goodwill

You don’t need to be a household name, but you do need to show that customers in your market recognise your sign, get‑up or name as distinguishing your business. Evidence can include sales figures, marketing materials, website analytics, media coverage, awards and customer reviews.

Misrepresentation

This is often assessed from the perspective of the ordinary consumer. Would a reasonable person in your market be likely to be deceived? Similarity in names, logos, packaging, colour schemes, website layouts and store fitouts can all matter. You don’t need to prove intent to mislead-only a likelihood of deception.

Damage

Damage may be immediate (lost sales) or longer term (erosion of brand value). You can show evidence of customer confusion, diverted traffic, customer complaints or price undercutting that leverages your goodwill. Sometimes, the court will infer damage if misrepresentation is clear and you have an established reputation.

Practical Steps To Prevent Passing Off Against Your Brand

Prevention is usually faster, cheaper and more effective than trying to undo damage later. These steps will help you strengthen your position before issues arise.

1) Lock In Your Core Brand Assets

• Register your key signs (name, logo, tagline) as trade marks covering the right goods/services and classes.
• Use your brand consistently across packaging, labels, website and socials so consumers quickly associate those elements with you.
• Keep a record of first use dates, brand guidelines and marketing spend to help prove reputation if needed.

If you haven’t already, consider an application to register your trade mark and choose appropriate trade mark classes for current and future product lines.

2) Use Clear Contracts With Partners And Suppliers

• When licensing your brand to others (e.g. wholesale partners or distributors), set standards and permitted uses in an IP Licence so your get‑up and quality are protected.
• When collaborating or sharing sensitive brand assets before launch, put a Non‑Disclosure Agreement in place to reduce leakage or misuse.

3) Monitor The Market Proactively

• Set up alerts for new domains, social handles and search ads that use your key brand terms.
• Regularly scan marketplaces and retail shelves for look‑alike products or get‑up.
• Encourage your team and customers to report suspicious listings or sites.

4) Use Brand Guidelines And Notices

• Publish brand guidelines for internal and external use so your brand is applied consistently.
• Use ® or ™ symbols where appropriate and include brief IP ownership notices on your website and packaging.

What To Do If Someone Is Passing Off Your Business

Act quickly but strategically. Early intervention can stop confusion before it spreads.

Step 1: Gather Your Evidence

Save screenshots, purchase samples, record dates and keep copies of customer complaints or confused enquiries. Collect proof of your reputation (sales, marketing, press, awards). The more organised your file, the stronger your position.

Step 2: Assess Your Legal Options

Consider a mix of claims and forums. Depending on the facts, you may rely on trade mark infringement, passing off and ACL claims (including section 18 and section 29). A tailored strategy can drive a quicker resolution-sometimes without going to court.

Step 3: Send A Strong, Targeted Letter

In many cases, a well‑drafted letter of demand is enough to achieve a rebrand, product withdrawal or other practical fix. It should clearly outline your rights, the misrepresentation and the outcome you seek. If you need guidance, you can get support with creating a cease and desist letter so it hits the right legal notes.

Step 4: Consider Platforms And Administrative Options

Where the conduct occurs on marketplaces, social media or through search ads, use their takedown or impersonation policies. While these aren’t a substitute for legal rights, they can deliver fast, practical results.

Step 5: Seek Court Orders If Needed

If the matter can’t be resolved informally, you may seek court remedies such as an injunction (to stop the conduct), damages or an account of profits, delivery up/destruction of infringing materials, and corrective advertising.

Time matters. If confusion is spreading, swift action can minimise the damage to your goodwill.

How Passing Off Issues Commonly Arise (And How To Handle Them)

Passing off risks can pop up in many day‑to‑day scenarios for small businesses. Being aware of them helps you react quickly and calmly.

Look‑Alike Packaging And Product Get‑Up

Retail shelves are competitive, and “me‑too” products are common. If a competitor’s packaging, colour palette and layout create a real risk of customer confusion, gather side‑by‑side images, sample products and any evidence of mis‑scans at checkout or mistaken purchases. Pair a passing off argument with trade mark rights (if registered) and ACL claims for a stronger approach.

Digital Confusion: Domains, Socials And Search

Confusing domain registrations, social handles and search ads (particularly those that mimic your brand in ad text or landing pages) can be fertile ground for misrepresentation. Preserve evidence including search terms, ad screenshots and analytics showing diverted traffic. Platform takedowns plus a targeted legal letter can be effective.

Implied Endorsements And Collaborations

If another brand implies you endorse or sponsor them without consent, that can misappropriate your goodwill. Keep your brand licensing terms tight in any IP Licence, and act quickly if you see unauthorised “as seen with” or “official partner” claims.

Rebrands And Business Name Collisions

Sometimes a clash is accidental. If a newer business adopts a name close to yours and trades in similar goods/services, a practical path might be a managed rebrand timeline with clear undertakings. Evidence of your earlier use and reputation will be key.

Frequently Asked Questions About Passing Off (For Business Owners)

Do I need a registered trade mark to claim passing off?

No. Passing off protects your goodwill even without registration. That said, a trade mark is typically easier to enforce and pairs well with passing off.

Is copying my colour scheme enough to be passing off?

Colour alone is rarely decisive. Courts look at the overall impression-name, logo, trade dress, layout and how the products are presented to consumers.

What if I operate only online-is passing off still relevant?

Absolutely. Website design, domain names, search ads and social profiles can all create misleading associations that support a passing off and ACL claim.

Can good intentions be a defence?

Not usually. Passing off focuses on the effect on consumers, not the other party’s intent. Honest mistakes can still mislead and cause damage.

How quickly should I act?

As soon as you can. Early action limits customer confusion and strengthens your case for urgent remedies like an injunction.
