How to Register a .com.au Domain

Registering a .com.au domain is straightforward when you know what to prepare. The expensive mistakes happen when people rush past the eligibility check, use the wrong registrant details or choose a name customers cannot remember.

This guide walks you through the entire process in plain English. By the end, you will know whether you are likely to qualify, how your domain must connect to your business, what information to gather and how to protect the name after registration.

Before you start: make one decision that saves a lot of trouble

Decide who should legally hold the domain licence. This sounds obvious, but it is where many avoidable problems begin.

If the domain belongs to your business, the registrant details should identify the eligible person or entity that is meant to control it. A web designer, employee or marketing agency can register it on your behalf with permission, but they should use your details—not theirs. Access to an account is not the same as being recorded as the licence holder.

Why does this matter? Because your domain may eventually control your website, business email and a large share of your customer enquiries. If it is registered under somebody else’s details, renewing, transferring or recovering it can become unnecessarily difficult. Start clean. Record the correct eligible registrant from day one.

Have these details ready

The proposed registrant’s legal name and contact details.
The relevant ABN, ACN, ARBN or Australian trade mark information.
Two or three domain-name options in case your first choice is unavailable.
An email address you can access independently of the new domain.
A secure payment method and a password manager.

Who can register a .com.au domain?

A .com.au domain is intended for commercial entities with a connection to Australia. According to auDA, eligible holders can include entities registered to trade in Australia and holders or applicants of an Australian trade mark. For many small businesses, the most common evidence is an active ABN or ACN. Other accepted pathways can include an ARBN or qualifying Australian trade mark details.

An Australian street address is not automatically required. The key issue is whether you meet the Australian commercial entity presence requirements. You must be eligible when you register and remain eligible for as long as you hold the licence.

Do not treat this article as a substitute for the rules. Eligibility depends on your circumstances, and auDA’s licensing rules can be amended. Before purchasing, check the current auDA Licensing Rules or ask your registrar to confirm the correct basis for your application.

Do you need an ABN?

An ABN or ACN is the usual route for Australian businesses, but it is not the only possible route. A foreign company with an ARBN, or a person or entity relying on an Australian trade mark, may also qualify under the rules. Trade mark-based eligibility is more restrictive because the domain generally needs to be an exact match of the words covered by the application or registration.

If you are still unsure, read Do I need an ABN for a .com.au domain? and Who can register a .com.au domain? before entering your details.

Your chosen name must connect to your business

Availability is only half the test. A .com.au name must also meet auDA’s allocation criteria by having the required connection to the registrant.

The connection may be your exact business, company or personal name; an acronym of that name; a matching Australian trade mark; or a match or synonym for goods, services, activities, events or premises associated with the business. For example, an eligible plumbing business may be able to register a name based on its trading name or the plumbing services it provides.

Choose the simplest defensible connection. If the registrar asks why the name relates to the business, you should be able to explain it clearly and support the answer. Avoid assuming that a broadly attractive generic phrase is automatically available to you merely because you intend to use it for marketing.

Choose for people, not just keywords

A domain can contain a relevant service term, but it still needs to work in real life. Keep it short, easy to pronounce and easy to type. Avoid numbers and hyphens where possible. Say the name aloud to five people and ask them to write it down. If they regularly get it wrong, the domain will leak attention every time you mention it on the phone, in a video or at a networking event.

Also check business-name records, IP Australia’s trade mark search and major social platforms. Registering a domain does not grant trade mark rights, and an available name can still create a branding or legal problem.

How to register a .com.au domain step by step

Choose two or three sensible names. Start with your exact business name. If it is unavailable, try a clear service or location modifier rather than random numbers or awkward spelling.
Search availability. Use a domain provider’s search tool to check whether the name can be registered. A search result is not final approval; eligibility and allocation rules still apply.
Check the name’s connection. Make sure the proposed domain matches or relates to the registrant in a way permitted by the current rules.
Select a reputable provider. Register through an auDA-accredited registrar or an authorised reseller. Compare renewal prices, support, account security and management tools—not only the first-year offer.
Enter the registrant information. Provide accurate legal and contact details plus the requested ABN, ACN, ARBN or trade mark basis. Double-check every field before submitting.
Choose the licence term. .com.au licences may be registered for one, two, three, four or five years, although not every provider offers every term.
Review the checkout. Remove extras you do not need, confirm the future renewal cost and read the provider’s refund and service terms.
Complete registration. Pay, save the receipt and keep the confirmation showing the domain, registrant and licence term.
Secure the account immediately. Use a unique password, enable multi-factor authentication and store recovery details safely.
Switch on renewal protection. Enable automatic renewal, keep the payment method current and create an independent calendar reminder.

That is the whole process. You do not need to understand registry infrastructure or memorise policy language. You need a suitable name, a valid connection, accurate registrant details and a provider you can rely on.

Ready when you are

Find your .com.au before somebody else does.

.au domain names are generally allocated on a first-come, first-served basis to the first eligible registrant. If you have found a clear name that fits your business and you meet the rules, delaying does not improve the opportunity.

How about price, registration terms and refunds?

Domain prices vary by provider. Promotional first-year pricing can look attractive, but the renewal price is the number that affects you year after year. Before purchasing, compare the complete cost over the licence term, including optional privacy, email, hosting or security products.

A .com.au licence can be registered for between one and five years at a time. You can renew at the end of the term if you continue to meet the eligibility requirements. Some providers may offer only shorter registration periods.

auDA’s rules include a three-calendar-day cooling-off period in which a new registration can be requested for deletion. auDA refunds the wholesale registration fee to the provider, but whether the provider refunds you depends on its own policy. Read the refund terms before payment rather than assuming every charge will be returned.

Remember that you receive a licence to use the domain for its term; you do not acquire unrestricted property rights in the name. Continue meeting the eligibility rules and keep the registrant information accurate.

What to do immediately after registration

First, confirm that the registrant name and contact email are correct. Keep the confirmation somewhere accessible to the business owner. If an agency manages the domain, retain your own login or documented recovery process.

Next, decide what the domain will do. You can connect it to a website, use it for professional email or redirect it to an existing address. Your web host or email provider will give you DNS records to add. Copy the existing records before changing anything and ask for support if the instructions are unclear.

For a website, use HTTPS with a valid SSL certificate and select one primary address. Redirect variants—such as the version with or without “www”—to that preferred version. If you also register the matching .au direct name for brand protection, redirect it rather than creating duplicate websites.

For email, configure the provider’s recommended SPF, DKIM and DMARC records. These help receiving systems verify legitimate messages and reduce the risk of criminals impersonating your domain. Use role-based addresses such as hello@ or accounts@ only where they suit the business, and protect every mailbox with multi-factor authentication.

Seven registration mistakes that cost more than the domain

Using the web designer’s details. Your supplier can assist, but the correct eligible person or entity should be recorded as registrant.
Entering an expired or unrelated ABN. Verify the identifier and its connection before checkout.
Choosing a name that fails the allocation criteria. Available does not automatically mean eligible.
Ignoring trade marks. Domain registration is not permission to use somebody else’s protected brand.
Buying on introductory price alone. Check renewal charges and the service you receive after the promotion ends.
Using the new domain email as the only recovery address. If DNS or email fails, you could lock yourself out of the recovery path.
Forgetting renewal. Automatic renewal plus an independent reminder is a simple defence against disruption.

Frequently asked questions

Can anybody register a .com.au domain?

No. .com.au is for eligible commercial entities with an Australian connection, and the chosen name must meet the allocation criteria. Check the current auDA rules for your circumstances.

How quickly can a .com.au domain become active?

Many providers automate registration, so an eligible application with accurate information may be processed quickly. Connecting a website or email can take additional time while DNS changes propagate.

Can my web designer register it for me?

Yes, with your explicit written permission. They should enter your eligible registrant and contact details. You remain responsible for the information supplied.

Do I need a website before I register?

Generally, no. A domain can be held before the website is ready and can be used for professional email. However, eligibility and the required connection to the name still apply.

Should I register the matching .au name?

It can be worthwhile for brand protection if the budget allows and you are eligible. Choose one primary domain and redirect the other to it.

What if my first choice is already taken?

Try a clear abbreviation, service term or location connected to the business, or compare another appropriate namespace. Avoid a confusing imitation of an existing brand.

Once your domain is registered, the next useful step is to connect it to a website and professional email that make the business look as credible as the name suggests.
