.au Domain: Australia's Official Country Extension
.au is the country code top-level domain (ccTLD) of Australia, entered into the root zone on 5 March 1986. The zone is administered by .au Domain Administration (auDA). For decades the extension was used only through second-level names such as com.au or org.au; registering directly at the second level, giving you a short yourbrand.au address, opened on 24 March 2022. For businesses wanting a shorter address in the Australian market, that date is the real turning point.
Second-level .au names are open to organisations and individuals alike, and the decisive condition is Australian presence. If you trade commercially, .com.au positions you more precisely; if you are a not-for-profit, .org.au does. .au itself draws no such distinction and simply gives you the shortest form of your name. Holding both the com.au and the .au version of a name keeps visitors from landing on the wrong address and stops your brand splitting in two.
You can establish Australian presence with an ABN, ACN or ARBN, a registered business name, Australian citizenship or permanent residency; for applicants without a company in the country, the route is an Australian registered trade mark. Without that connection an application is refused at registration and the name is not held for you. Working out which evidence fits your case at the start is the practical way to avoid a drawn-out process. Check whether your preferred name is free using domain search.

.au Domain Lifecycle
What happens day by day after it expires
Day 0 is the domain's expiry dateIn short: for .au the post-expiry timeline is set by the registry, so it differs from one extension to the next. The diagram below shows the windows that actually apply to .au, day by day. One thing never changes, whichever extension you hold: renewing before the expiry date is always the cheapest and safest route.
Domain Is Available (Available)
A .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 registered to you for the term you selected. You can renew at any point before it expires to keep it active, or switch on auto-renewal so you never have to watch the date.
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 .au Domains
The questions people actually ask before registering — answered plainly.
-
Second-level .au names are open to organisations and individuals alike; the only condition is Australian presence. Australian citizens and permanent residents meet it inherently, while companies meet it through an ABN, ACN, ARBN or a registered business name. Unlike com.au and org.au, the extension does not ask whether the applicant is commercial or not-for-profit, so personal projects can register too. Where no connection can be shown, the registration is not completed.
-
.au is the short address taken directly at the second level and does not look at what type of applicant you are. .com.au is open only to commercial entities and requires the name to connect to your company name, trade mark or the services you provide. In practice: choose .au for a short, unrestricted name, and .com.au when you want the address itself to signal commercial identity. Many businesses hold both and redirect one to the other.
-
The requirement demonstrates a genuine connection to the country. For local businesses an ABN, ACN or ARBN, or a registered business name, is enough. Individuals meet it through citizenship or permanent residency. Organisations with no registered structure in the country meet it through an Australian registered trade mark. You do not need to open a physical office in Australia; what is required is a registered connection, not an address.
-
Yes, but the Australian presence requirement applies to applicants abroad as well. If you have no registered business in the country, you can establish the connection through an Australian registered trade mark or a trade mark application. Where an application rests on a trade mark, the rules limit how the domain may relate to it; on the .com.au side the name must be an exact match to the words of the mark. Have your evidence ready before applying.
-
No. When second-level .au registrations opened on 24 March 2022, a period ran that gave existing com.au, org.au and net.au holders priority to apply for the .au version of their name. That period closed on 20 September 2022. Today .au names go to the first eligible applicant. So if the name you want is free, waiting gains you nothing — the order of applications decides the outcome.
-
.au names can be moved between providers. Transferring does not remove the eligibility condition: your Australian presence must still hold under the new registration record, otherwise the transfer does not complete. The remaining registration period is preserved after the move, and your website and email keep working uninterrupted as long as you do not change name servers. You can start on the domain transfer page.
-
You can see whether a .au name is registered, and the general state of the record, through its WHOIS entry. Because of data protection obligations the registry publishes registrant contact details only in limited form, so a lookup will usually show you the status of the name and its registration dates. Run the lookup on the whois search page, and check whether a name is still free with domain search.
