Can Two Businesses Have Similar Names in Australia? Trademark Rules Explained

It's a question that catches a lot of Australian business owners off guard: you spot another company trading under a name almost identical to yours, and suddenly you're not sure where you stand. Sometimes two similar names can sit side by side without any legal issue at all. Other times, one business is quietly infringing on the other's trademark rights without even realising it. The difference usually comes down to a handful of legal tests that most people never think about until a name clash actually happens to them.

Business Names and Trademarks Are Not the Same Thing

A huge amount of confusion around this topic starts with one simple misunderstanding: registering a business name with ASIC is not the same as owning trademark rights. ASIC's business name register only checks that your chosen name isn't identical to another currently registered business name. It doesn't check industries, doesn't check logos, and doesn't check whether the name is already trademarked somewhere else entirely.

That's why a name can sail through ASIC registration and still get knocked back, or challenged, at the trademark level. Reviewing the categories that stop a mark from being registered in the first place is a useful starting point before assuming a name is automatically safe to build a brand around.

Why Similar Names Are Sometimes Allowed to Coexist

Trademark protection in Australia is tied to specific classes of goods and services, not to a name in isolation. This is why a landscaping company and a software company can both legally trade under almost the same name without any conflict at all — customers aren't likely to confuse a garden care service with a piece of business software, and the two operate in entirely unrelated markets.

• The businesses operate in genuinely different industries or classes
• The names are only loosely similar rather than near-identical
• Neither business trades in a way that overlaps with the other's customer base
• Neither name has been formally registered as a trademark by either party

Once any of those conditions changes, particularly if one business later expands into the other's market, coexistence can stop being safe overnight.

When a Similar Name Crosses the Legal Line

IP Australia and the courts apply a test called "deceptive similarity" when deciding whether one name infringes on another. Put simply, if an ordinary customer could reasonably mistake one business for the other, or assume some kind of connection between them, that's usually enough to establish a conflict.

The Deceptive Similarity Test

This test looks at how the names sound, how they're spelt, and the overall impression they create, rather than requiring an exact letter-for-letter match. A name that's spelt differently but sounds almost identical when spoken can still fail the test. Overlapping industries make this comparison far stricter, which is exactly why so many rejected applications trace back to a name that was simply too close to something already on the register.

Operating in the Same or Related Industries

Even names that aren't perfectly identical can cause trouble if both businesses sell related goods or services to the same type of customer. A café and a catering company sharing a similar name, for instance, sit close enough together that confusion becomes genuinely likely. This is one of the most frequent triggers for a formal dispute during the window where third parties can challenge a pending application before it proceeds to registration.

What Happens If Another Business Copies Your Name

If your name is a registered trademark and another business starts trading under something confusingly similar, you generally have the right to take action, including sending a cease and desist letter, opposing their pending application, or pursuing a formal infringement claim. Without a registered trademark, though, your options shrink considerably. You'd typically need to rely on common law "passing off" claims, which are harder, slower, and more expensive to prove than a straightforward trademark dispute.

Founders who skip early name protection often discover this the hard way. It's a pattern explored in more detail in the piece on why growing companies sometimes lose control of the brand name they built, where a delay in filing gave a competitor the opportunity to register first.

Protecting Your Name Before Someone Else Does

Australia runs on a first-to-file system, which means the business that lodges its trademark application first generally wins the rights to that name within its registered class, regardless of who started trading first. Waiting until a dispute actually happens is the riskiest possible approach.

• Run a proper clearance search across the IP Australia register before settling on a name
• File your trademark application as early as possible, ideally before launch
• Keep a written record of your first use of the name in trade
• Monitor new applications so you can act during the opposition window if a conflict appears

A domain name or social handle offers no legal protection on its own either. As covered in the guide on whether owning your web address is enough to secure your brand, plenty of businesses assume an available domain means the name is free to use, only to find out later it was already trademarked in their industry.

Common Pitfalls When Choosing a Name

Beyond the direct conflict risk, plenty of small businesses stumble into avoidable naming mistakes long before a competitor ever enters the picture. The rundown of frequent missteps Australian small businesses make with their branding covers several of these, from filing too late to choosing a name that was never distinctive enough to defend in the first place. Running a proper search early, similar to the process outlined in the steps for confirming a name is genuinely free to use before launch, saves considerable time and legal cost down the track.

Local Support Across Queensland

If a name conflict does surface, the right next step depends on the situation. Some businesses find the cleanest resolution is negotiating a formal transfer of an existing trademark from its current owner, rather than starting the naming process over. Others prefer to keep ownership and instead arrange permission for another party to use the name under agreed terms, supported by a properly drafted agreement that keeps those terms enforceable. Businesses juggling both branding and product innovation may also benefit from specialist patent guidance alongside their trademark strategy, so nothing falls through the gap between the two systems.

Ready to Protect Your Business Name?

Two businesses can absolutely share a similar name in Australia, provided they trade in genuinely different markets and neither name has been locked down through trademark registration. The moment industries overlap, or one party files first, the legal picture changes fast. Filing early, searching thoroughly, and treating your business name as a protectable asset from day one is the simplest way to avoid finding out the hard way that someone else got there first.
