A Founder's Guide to Business Name Registration in Western Australia

Monday 23 March 2026•10 min read

You have the idea. You've mapped out the vision. Now it's time to give your Western Australian venture a name, a legal identity that lets you open your doors and start trading. This step can feel like a bureaucratic hurdle, but it's a foundational piece of your business puzzle. Getting it right from the start saves you significant headaches later.

This guide isn't about generic national advice. It's a practical walkthrough for founders right here in WA. We'll cover the essential ASIC process, highlight state-specific considerations, and outline the critical next steps that turn a registered name into a powerful brand.

First, Why Register a Business Name at All?

Before we get into the how, let's clarify the why. In Australia, you are legally required to register a business name if you conduct business under a name that is not your own.

For a sole trader, if your name is Jane Smith and you trade as 'Jane Smith', you don't need to register a business name. If you trade as 'Jane's Coastal Creations', you absolutely do. The same applies to partnerships, trusts, and companies trading under a name different from their registered legal entity name.

It's important to understand the difference:

Business Name: A trading name registered with the Australian Securities and Investments Commission (ASIC). It links your ABN to the name you trade under. It does not create a separate legal entity.
Company Name: The legal name of a proprietary limited (Pty Ltd) company. This is registered when you incorporate the company and it creates a separate legal entity.
Trademark: A form of intellectual property protection for your brand elements, like your name or logo. It gives you exclusive rights to use that brand element for specific goods or services.

:::warning Registering a business name does not give you trademark protection. This is a common and costly point of confusion for new founders. Only a registered trademark offers legal protection against others using your name. :::

The How-To: Your Guide to Business Name Registration in Western Australia

The national system, managed by ASIC, makes the core process for business name registration in Western Australia the same as in any other state. Here's exactly what you need to do.

:::steps

Step 1: Check if Your Name is Available

Search ASIC's business names register for identical names and phonetic variations. Also search Google, social media, and IP Australia's trademark database to prevent future clashes. ---

Step 2: Get Your Australian Business Number (ABN)

You cannot register a business name without an ABN. Apply for free through the Australian Business Register (ABR). Approval is often instant. ---

Step 3: Complete the Registration on ASIC Connect

Log in to the ASIC Connect portal, select 'Business Names', provide your ABN, proposed name, registration period, and business addresses. Pay the fee and receive your registration certificate via email. :::

Step 1: Check if Your Name is Available

Your brilliant name idea might already be taken. Your first action is to check ASIC's 'Search business names register'. Look for identical names and phonetic variations. If your name is 'Clearview Windows', you should also check for 'Klearview Wyndows'. A name that is too similar to an existing one will likely be rejected.

While you're there, perform a quick search on Google, social media platforms, and Australia's trademark database (IP Australia's ATMOSS search). This simple check can prevent future brand clashes or legal issues.

Step 2: Get Your Australian Business Number (ABN)

You cannot register a business name without an ABN. An ABN is a unique 11-digit number that identifies your business to the government and community. If you don't have one yet, you can apply for free through the Australian Business Register (ABR).

Applying for an ABN is straightforward. You will need to provide proof of identity and details about your business structure and activities. Approval is often instant.

Step 3: Complete the Registration on ASIC Connect

With your ABN in hand and your name confirmed as available, you're ready to formally register your business name in WA.

Go to the ASIC Connect portal and log in or create an account.
Select 'Business Names' from the 'Licences and Registrations' menu.
You will be asked for your ABN, the proposed business name, and the registration period you want (one or three years).
You must provide addresses for your business. You need a physical address for service of documents in Australia (this cannot be a post office box) and a principal place of business. For many WA startups, this might be your home address initially.
Finally, you'll pay the registration fee. Once payment is confirmed, your name is typically registered immediately. ASIC will email you the record of registration, and you should display the name certificate at your principal place of business.

:::tip Opt for the three-year registration period. It provides peace of mind, is more cost-effective, and means one less thing to worry about during your critical early years. :::

Costs and Timelines for WA Founders

Registering a business name is one of the most affordable steps in starting up.

:::stat $39 | One-Year Registration | The ASIC fee for a one-year business name registration :::

:::stat $92 | Three-Year Registration | The recommended option — more cost-effective and less admin :::

Cost: As of early 2024, the ASIC fee is $39 for a one-year registration or $92 for a three-year registration. Opting for three years provides peace of mind and is more cost-effective.
Timeline: The online application is fast. Provided your name is available and your details are correct, registration is almost instantaneous. You'll receive your official confirmation and certificate via email, often within the hour.

:::stat Instant | Typical Approval Time | Your registration is confirmed within minutes of payment, with your certificate emailed within the hour :::

Remember to set a calendar reminder for your renewal. If you let your registration lapse, another business can claim your name.

Beyond ASIC: WA-Specific Considerations

While the registration is national, operating in Western Australia comes with its own context.

Certain industries in WA have state-level licensing and registration requirements that can intersect with your business name. For example, if you're in the building industry, your trading name must be associated with your registration with the Building Services Board. Similarly, real estate agents must be licensed through DMIRS (Department of Mines, Industry Regulation and Safety), and their trading names are part of that public record.

:::important Before you fall in love with a name, check if your industry has a governing body in WA and understand its specific rules. This ensures your chosen name is compliant not just with ASIC, but with the state authorities who oversee your sector. :::

Secure Your Digital Territory: Choosing a Domain Name

Here is a critical piece of advice: do not register your business name until you have checked for the corresponding domain name. The moment you find an available business name, your very next click should be to a domain registrar.

For a business focused on the local market, your domain name is your digital address. It builds credibility and makes you discoverable.

Domain Options for WA Businesses:

.com.au: This is the trusted standard for Australian businesses. It signals to customers that you are a legitimate local entity.
.au: The newer, shorter alternative. It's clean, modern, and becoming increasingly popular for Australian brands.
.perth: A powerful option for businesses that are geographically focused on the Perth metropolitan area. It's an immediate signal for services like plumbers, cafes, or local consultants.

:::tip For WA businesses serving the Perth metro area, consider securing both a .com.au and a .perth domain. The .perth TLD is a powerful local signal for services like trades, hospitality, and consulting. :::

Imagine the frustration of securing 'Fremantle Coffee Roasters' as a business name, only to discover that fremantlecoffeeroasters.com.au was snapped up years ago. This happens every day.

At Dotto, we help founders avoid this exact problem. We've curated a selection of premium, brandable .au domains that are perfect for ambitious WA startups. Securing a great domain from the outset gives your brand a professional edge.

Common Mistakes WA Founders Make

Learning from others is a powerful shortcut. Here are some common missteps we see founders in Perth and across WA make.

:::checklist

[ ] Confirm your business name is NOT the same as a trademark (ASIC registration is not trademark protection)
[ ] Set multiple calendar reminders for your registration renewal date
[ ] Consider your growth ambitions before choosing a geographically-specific name
[ ] Secure matching social media handles on Instagram, Facebook, and LinkedIn
[ ] Verify domain availability BEFORE registering your business name with ASIC

:::

Assuming a Business Name is a Trademark. It is not. Registering your name with ASIC does not stop someone else from using it, nor does it give you legal recourse if they do. Only a registered trademark offers that level of protection.
Forgetting to Renew. Life gets busy, and an email reminder from ASIC can get lost. A lapsed registration means your name is fair game. Use a calendar, set multiple reminders, and pay for the three-year option.
Choosing a Geographically Limiting Name. 'Mandurah Marketing Solutions' might sound great today, but what happens when you want to win clients in Bunbury or the Perth CBD? Be strategic. A location-based name is excellent for a purely local service business, but it can be restrictive if you have ambitions to grow across the state or nation.
Not Securing Social Media Handles. At the same time you check your business name and domain, check for the name's availability on Instagram, Facebook, LinkedIn, and any other platform relevant to your audience. Brand consistency across all channels is key.

Congratulations. You've completed a vital step in your Western Australia business registration journey. You are now legally entitled to trade under your chosen name.

The work doesn't stop here. This is where the brand building begins. Your name is the anchor, but now you need to build the ship. This involves:

Building your website on the domain you wisely secured.
Setting up your business bank account using your ABN and business name certificate.
Creating your marketing materials with consistent branding.
