To register a .com.au domain, you need an Australian commercial presence and a legitimate connection to the name you want.
That sounds formal. In practice, many Australian businesses qualify through an active ABN or ACN. Other eligible bases can include an ARBN or an Australian trade mark application or registration. The part people miss is that eligibility and the domain-name connection are separate checks.
Get both right before paying and registration is usually straightforward. This guide explains the core .com.au domain requirements in plain English.
Who meets the .com.au eligibility requirements?
The .com.au namespace is intended for commercial use. Eligible registrants can include Australian companies, registrable bodies, incorporated associations, entities or natural persons with an ABN, eligible trusts and partnerships, trading cooperatives, commercial statutory bodies, government entities, and foreign legal entities or natural persons relying on a relevant Australian trade mark.
For many small businesses, an active ABN connected to the registrant is the most familiar route. But an ABN by itself does not mean you can register any available .com.au name. The proposed domain must also satisfy an allocation rule.
If your structure or eligibility basis is unusual, check the current auDA rules and policies or ask your registrar before registering. Rules can change, and the official policy takes priority over any general guide.
What .com.au domain name can you register?
Your domain generally needs a valid connection to you or your business. Common routes include:
- an exact match, acronym or abbreviation of the registrant’s company, business, partnership or organisation name;
- a match to an eligible Australian trade mark held or applied for by the registrant; or
- a name closely connected to the registrant’s goods, services, profession, activity or premises.
Imagine a fictional business called Northline Plumbing Pty Ltd. A domain based on “Northline Plumbing” may connect through the company name. A descriptive address connected to plumbing services may potentially rely on the close-connection test. The registrar may request evidence, so choose a name you can support rather than one that merely happens to be available.
Trade-mark eligibility has additional limits. The domain must meet the applicable rule for the trade mark rather than functioning as a free pass to unrelated names.
What information is needed to register?
Have the legal registrant details ready before you start. Depending on the eligibility basis, this may include the registrant’s legal name, ABN or ACN, registered business name, trade-mark details and current contact information.
Enter the real business or eligible person as the registrant. Do not leave the licence permanently under a web designer, employee or marketing agency simply because they performed the setup. They can manage technical records without holding the licence in their own name.
The registrant information must remain accurate. Use an email address the registrant can access independently of the domain being registered, so renewal or recovery messages still arrive if the business email stops working.
Does the domain have to match the business name?
Not always. An exact or abbreviated match is one common pathway, but a closely connected name may also qualify. The important point is that the relationship must be genuine and fit the current allocation rules.
Choose for customers as well as compliance. A short, memorable address connected to your actual brand or service will usually outperform a long string of keywords. Google’s current guidance prioritises useful, people-first content; the domain alone cannot replace a credible website.
You must remain eligible after registration
A .com.au registration is a renewable licence, not permanent property. You must continue meeting the eligibility and allocation requirements while holding it. Update the details after a restructure, sale, business-name change or contact change, and use the correct registrant-transfer process when the licence holder changes.
Turn on multi-factor authentication and automatic renewal, keep payment details current and add an independent expiry reminder. Compliance gets you the domain; good account management helps you keep it.
