.com.au domain registration for Australian businesses
The address Australians trust most. Register your .com.au for two years, with DNS management, renewal reminders and real local support included.
The short answer
A .com.au is the domain extension for businesses registered in Australia. You need an ABN, ACN or an Australian trade mark to register one, and the name must match or relate to your business. With us, a .com.au costs $80 + GST for two years, with DNS management and renewal reminders included.
Why Australians trust a .com.au
A .com.au tells customers you’re a real Australian business before they even click. auDA’s own 2026 research found 8 in 10 Australian consumers are more likely to trust a business with a .au website.
It also helps you show up in the right place. A country-code domain is a strong signal to Google that your site is meant for Australian searchers, which is where most small businesses find their customers.
It’s the most popular choice by a long way. There were more than 3.3 million .com.au names registered in October 2026, about three quarters of all .au domains.
Who can register a .com.au?
You need to be a business that’s registered to trade in Australia, or own an Australian trade mark. Any one of these will do:
An ABN
Sole traders, partnerships, trusts and companies with an active Australian Business Number.
An ACN or ARBN
Australian companies (ACN) and foreign companies registered to trade here (ARBN).
An Australian trade mark
A registered trade mark, or a pending application, that matches the domain name.
The name itself has to match or abbreviate your business name or trade mark, or describe a product or service you offer. Since 20 May 2026, a .com.au also won’t renew if the ABN or ACN behind it has been cancelled. Read who can register a .com.au for the details.

.com.au vs .au vs .com
Most Australian businesses start with a .com.au. Here’s how it compares with the shorter .au and the global .com.
| .com.au | .au | .com | |
|---|---|---|---|
| Who can register | Businesses with an ABN, ACN or trade mark | Anyone with an Australian presence | Anyone, anywhere |
| Name rules | Must match or relate to your business | Any available name | Any available name |
| Signals Australia | Yes, strongly | Yes | No |
| Best for | Your main business website | Protecting your brand, short links | Selling overseas |
Many businesses register more than one. See .au direct domains and international domains for when that makes sense.

.com.au domain FAQs
Do I need an ABN to register a .com.au?
You need an ABN, an ACN, an ARBN or an Australian trade mark (registered or applied for). Without one of these, consider a .au direct domain, which is open to anyone with an Australian presence.
How much does a .com.au domain cost?
With us, $80 + GST for two years. We don’t use first-year discounts, so you renew at the same fair price.
How long does it take to register a .com.au?
Usually a few minutes. Your eligibility is checked automatically against the business register, then the domain is live.
Can I register a .com.au as a sole trader?
Yes. A sole trader with an active ABN is eligible. The domain should match your business name or describe what you do.
What happens if my ABN is cancelled?
Since 20 May 2026, a .com.au won’t renew if the ABN or ACN behind it is no longer active. If your business structure has changed, update the registrant before renewal time.
Can I move my existing .com.au to you?
Yes. See our domain transfer page. Your website and email keep working during the move.
