New .com.au Domain Eligibility Rules: What Australian Businesses Need To Know

Choosing the right domain name is a big step for any Australian business. It’s often the first touchpoint customers have with your brand, and it plays a key role in trust, credibility and discoverability.

In recent years, auDA (the .au domain administrator) updated its Licensing Rules for .au domain names. These updates clarified who can register a .com.au, what your domain can be called, and when you might lose eligibility. If you’re registering a new name or renewing one you already hold, it’s worth making sure you still meet the rules.

This guide unpacks the current .com.au eligibility criteria in plain English, explains what changed, and walks you through how to choose and register a compliant domain. We’ll also cover the legal essentials for running your website in Australia so you can build a strong online presence with confidence.

What Is A .com.au Domain (And Why Does It Matter)?

A .com.au domain is the most common web address for commercial entities in Australia. The “.au” signals an Australian presence, which can help customers feel confident they’re dealing with a local business.

For many businesses, securing a matching .com.au is part of protecting their brand online. It helps people find you (and not an imitator), keeps your email addresses professional, and supports your local marketing and search efforts. You don’t legally need a .com.au to operate a business in Australia, but it’s often a smart move for brand protection and credibility.

What Changed Under The auDA Licensing Rules?

auDA consolidated and updated its Licensing Rules for .au domain names, which apply across the .au namespace (including .com.au and .net.au) and introduced direct .au names (for example, yourbrand.au). The headline changes that matter to most businesses are:

• Clearer eligibility criteria for .com.au names, including requirements around your Australian presence and the link between your domain and your business.
• Introduction of .au direct domain names (for example, yourbrand.au), which have different naming rules to .com.au. For .au direct, you still need an Australian presence, but there’s more flexibility in the name itself compared to the “close and substantial connection” test that applies to .com.au.
• More consistent enforcement of ongoing eligibility. If your underlying eligibility changes (for example, your registration is cancelled), you can lose your domain.

The result is a simpler, more consistent framework - but it also means business owners should double‑check that their current or planned domain still fits the rules.

Who Is Eligible To Register A .com.au?

You must meet two core requirements to register (and keep) a .com.au domain:

1) Australian Presence

You need a verifiable Australian presence. In practice, this usually means you have one of the following:

• An Australian Business Number (ABN)
• An Australian company with an ACN
• An Australian partnership, incorporated association or other local legal entity
• A foreign entity that holds an Australian registered trade mark

For many small businesses, an ABN is the simplest way to meet this requirement. Companies meet it through their ACN. Foreign businesses without a local entity can rely on an Australian trade mark (more on that below).

2) Name With A Close And Substantial Connection

For the .com.au namespace, the domain name must be closely connected to your business. It should be one of the following:

• Your exact company or business name
• An abbreviation or acronym of your name
• A product, service, event, activity or brand you provide
• A close and substantial connection to your operations (for example, a key project or product line)

This test is designed to prevent people from registering generic or unrelated names with no link to their business.

Special Rule For Foreign Applicants Using A Trade Mark

If you are using an Australian trade mark to satisfy the Australian presence requirement (for example, you’re a foreign company), the .com.au domain name must be an exact match to the words in your registered mark (ignoring punctuation, articles like “the”, and legal entity identifiers such as “Pty Ltd”). In other words, you can’t choose a different or broader term - it has to match the mark you’ve registered in Australia.

Ongoing Eligibility Matters

Your eligibility is assessed at registration and can be audited at any time. If your ABN or company registration is cancelled, or your trade mark lapses and you no longer meet the rules, your domain can be suspended or cancelled.

How To Choose And Register A Compliant .com.au

Registering your domain is straightforward once you’ve checked your eligibility. Here’s a simple, step‑by‑step approach.

Step 1: Decide Your Business Identity

Start by clarifying how you’ll operate. Will you trade as a sole trader, partnership or company? Your choice affects how you meet the Australian presence requirement and which name you’ll likely use for your domain.

If you’re weighing up a trading name for marketing alongside your legal entity name, it helps to understand the difference between a business name vs company name and how each appears on public registers and invoices.

Step 2: Check Your Eligibility Details

• Make sure your ABN or ACN details are current and match the entity that will hold the domain.
• If you’re relying on a trade mark for eligibility (especially as a foreign entity), confirm the mark is registered in Australia and the domain will be an exact match to the words of that mark.
• Confirm the person or entity named in the domain record can be contacted (use a monitored admin email).

Step 3: Choose A Name That Clearly Connects

Pick a domain that is an exact match, abbreviation or clear connection to your business, product or service. If your brand name is already taken, consider a close alternative that still passes the “close and substantial connection” test (for example, adding a product descriptor you actually sell).

At the same time, consider your broader brand protection strategy. Domain registration doesn’t give you exclusive brand rights. If your name is important to your business, registering a trade mark is usually the best way to protect it nationwide.

Step 4: Register With An Accredited Registrar

Use an auDA‑accredited registrar to register your .com.au for 1 or 2 years. You’ll be asked to provide your ABN/ACN or trade mark number, confirm eligibility and agree to the Licensing Rules. Keep all details accurate to avoid headaches later.

Step 5: Keep Your Records Updated

After registration, keep your eligibility and contact information current. If your business name changes or your structure changes (for example, moving from sole trader to company), update your domain records so they continue to match the new eligibility basis.

Common Pitfalls (And How To Avoid Them)

Most .com.au issues are avoidable with a few simple checks. Watch for the following:

• Losing your eligibility: If your ABN is cancelled, your company is deregistered or your trade mark lapses, you may lose your domain. Set reminders for key renewals and keep your details up to date.
• Choosing a name with no business link: Generic, unrelated names can be challenged. Pick something that clearly ties back to what you sell or who you are.
• Using a personal contact email that goes stale: If you change staff and lose access to the admin contact, you can miss critical notices. Use a shared inbox for domain administration.
• Not aligning your domain, business name and branding: Inconsistency confuses customers. Align your domain choice with your registered name and brand strategy.
• Relying on a pending trade mark: If eligibility depends on a registered trade mark, wait until it’s actually registered (not just filed) before you count on it for your .com.au.

Do .au Direct Domains (.au) Follow The Same Rules?

.au direct domains (for example, yourbrand.au) are available alongside .com.au. The key differences are:

• You still need an Australian presence to hold a .au direct name.
• The “close and substantial connection” test does not apply to .au direct in the same way; there’s more flexibility in naming. That said, the name must still not be reserved, prohibited or offensive and must meet other policies.
• Holding both your .com.au and .au direct versions can be a sensible brand protection step so others can’t register a confusingly similar address.

If you operate primarily in Australia, many businesses choose to secure both and redirect one to the other for consistency.

Legal Essentials For Your Website And Online Business

Registering your domain is the starting line. If your website collects customer data, sells products or provides services, there are a few legal building blocks you’ll want in place from day one.

Australian Consumer Law (ACL)

Any Australian business that sells goods or services must comply with the Australian Consumer Law. That includes accurate advertising, fair refund and returns policies, and not making misleading claims. Section 18 of the ACL prohibits misleading or deceptive conduct - a core rule that underpins your website content and marketing. If you’re unsure, read up on the Australian Consumer Law and align your site content and policies accordingly.

Privacy And Data Protection

If you collect personal information (names, emails, phone numbers, addresses or payment details), you’ll generally need a clear, accessible Privacy Policy that explains what you collect, why and how you store and share it. This isn’t just a box‑ticking exercise - customers expect it and regulators can ask to see it.

Website Terms And E‑Commerce Terms

Set the rules for using your site and, if you sell online, make sure your purchase process and terms are clear. Well‑drafted Website Terms and Conditions and product/service terms help prevent disputes and manage your liability.

Brand And IP Protection

Domains don’t grant exclusive rights to a brand. If your name, logo or tagline is important, consider registering a trade mark to lock in stronger protection across Australia. Also keep an eye on competing domain registrations that could confuse customers - early action is usually easier.

Business Structure And Records

Keep your underlying business details aligned with your domain. If you change from a sole trader to a company, update your domain record to the company, and ensure your ABN/ACN and registered business name details are consistent across your website, invoices and public listings.

FAQ: Practical Questions We Hear From Business Owners

Do I need a .com.au to trade in Australia?

No - you can legally operate without a .com.au. However, many businesses choose it for credibility, local recognition and brand protection. If your audience is primarily Australian, a .com.au often makes sense.

Can I register any word I like as my .com.au?

Not quite. Your .com.au must have a close and substantial connection to your business, product, service or brand. Generic words with no link to your activities often won’t be eligible.

What happens if I become ineligible after registering?

If you no longer meet the eligibility rules (for example, your ABN is cancelled), your domain can be suspended or cancelled. Keep your registrations active and your domain record up to date to avoid issues.

Is a domain the same as a trade mark?

No. A domain is an address on the internet. A trade mark is a legal right that protects your brand name or logo for specific goods and services. If your brand matters, consider both.

Can I transfer my .com.au to a new business entity?

Yes, provided the new holder is eligible and the transfer follows auDA policy. This is common when restructuring (for example, moving from sole trader to company). Plan the timing so your website and email aren’t disrupted.

Key Takeaways

• To register a .com.au, you need an Australian presence (for example, an ABN or ACN) and a domain name with a clear connection to your business, products or services.
• Foreign applicants relying on an Australian trade mark must register a .com.au that’s an exact match to the words of that mark.
• Eligibility is ongoing. If your ABN, ACN or other basis for eligibility lapses, your domain can be suspended or cancelled.
• .au direct names (yourbrand.au) have different naming rules but still require an Australian presence; many businesses secure both .com.au and .au for brand protection.
• Your website should comply with the Australian Consumer Law, include a clear Privacy Policy and have robust Website Terms and Conditions to manage risk.
• Domains don’t create brand ownership - consider a registered trade mark to protect your name and logo nationwide.
• Keep your business structure, registrations and domain records aligned, especially if you move to a company or adopt a new trading name, and understand the difference between a business name vs company name.
