.com.au Domain: Australia's Business Extension
.com.au is the commercial namespace under .au, Australia's country code domain. The zone is administered by .au Domain Administration (auDA); .au itself entered the root zone on 5 March 1986. The extension serves as the settled address for businesses selling into the Australian market, and it stands apart from generic alternatives anyone can register: a .com.au address is one where the rules genuinely test the applicant's commercial identity in the country.
The namespace is open only to commercial entities, and it requires the domain name to connect to the applicant. The accepted connections are: a match or acronym of the company, business or personal name; a match of an Australian registered trade mark; the name of a related Australian body corporate; or a match or synonym of the goods sold, services provided, events sponsored or activities carried out. Not-for-profits belong in .org.au, while .au is the short address that draws no such distinction.
For companies with no registered structure in Australia, the route is owning an Australian registered trade mark or having applied for one. Since 12 April 2021, an applicant relying solely on a trade mark must have a domain name that is an exact match to the words of that mark; abbreviations are not accepted. So if your mark is "Blue Harbour Coffee", blueharbourcoffee.com.au works and bhc.com.au does not. Use domain search to shortlist names that qualify.

.com.au Domain Lifecycle
Domain lifecycle
The stages in order, from registration to releaseDomain Is Available (Available)
A .com.au address at this stage has not been taken yet, and it goes to whoever registers first. Check the name you have in mind — if it is free, it can be yours within minutes.
Domain Is Active (Active Period)
Once registration is complete the domain is yours for the term you chose. You can renew at any point before expiry to keep it uninterrupted, or switch on auto-renewal so you never have to watch the date.
Redemption Period (Redemption Period)
The domain is not released the moment it expires — during this window it is still yours and can be recovered. Some extensions charge an extra restore fee at this stage, so renewing before expiry is always the cheaper route.
Pending Delete Period (Pending Delete Period)
If the redemption window is missed too, the domain enters the final stage and waits to be deleted. Renewal and recovery are no longer possible here; when the period ends the registration is removed for good.
Domain Is Available Again
Once deletion completes, the domain leaves the system and anyone can register it — popular names are often taken the same minute by someone watching. Keep auto-renewal on so a name you care about never gets this far.

Frequently Asked Questions About .com.au Domains
The questions people actually ask before registering — answered plainly.
-
The namespace is open only to commercial entities. Local companies show eligibility with an ABN, ACN or ARBN, or a registered business name; companies abroad show it by owning an Australian registered trade mark. Not-for-profit associations and charities cannot use this namespace — theirs is .org.au. Without evidence of eligibility the application is refused at registration and the name is not held for you.
-
The name must connect to the applicant, but that connection is defined in more than one way. A match or acronym of your company, business or personal name qualifies; so does your Australian registered trade mark or the name of a related Australian body corporate. If none of those fit, you may choose a name that is a match or synonym of the services you provide or the goods you sell. In other words, a name describing what you do is also accepted.
-
Yes. For companies with no registered business in Australia, the recognised route is owning an Australian registered trade mark or having filed an application for one. There is no requirement for a physical address or office in Australia. However, choosing this route means your domain name must be an exact match to the words of your mark, which noticeably narrows your options. A pending trade mark application is accepted as well.
-
An applicant relying solely on a trade mark for Australian presence must choose a domain made up of the words of that mark. In the assessment, the extension itself, punctuation, linking words such as 'a', 'the', 'and', 'or', 'of' and the '&' symbol may be disregarded; abbreviations and partial use of the mark are not accepted. The test took effect on 12 April 2021, replacing the earlier 'close and substantial connection' standard. In practice, short acronym names cannot be obtained this way.
-
Both require Australian presence but are open to different applicants. .com.au is for commercial entities. .org.au is reserved for not-for-profit organisations: incorporated associations, companies limited by guarantee, charities, registered unions, political parties and similar bodies. Which one you belong in follows from your legal structure, so rather than aiming at both, pick the one that matches how your organisation is constituted.
-
.com.au names can be moved between providers. A transfer does not remove your obligations: under the new record you must still be a commercial entity and still meet the Australian presence requirement. The remaining registration period is preserved after the move, and your site and email keep running without interruption as long as you do not change name servers. You can start on the domain transfer page.
-
An ABN is not the only way to show eligibility. An ACN or ARBN, or a registered business name, does the same job. If you hold none of these and have no registered structure in Australia, what remains is the Australian registered trade mark route. Because that route ties the domain to an exact match of the mark's words, planning your preferred name before you file the trade mark makes the process considerably easier.
