Buying a domain name in Australia is straightforward once you separate two decisions: which extension to register, and which registrar to buy it through. Most people jump straight to a search box. That is how you end up with a .net.au on the vans, or a .com.au sitting in a developer’s personal account.
This is the practical path we use with Australian businesses. For the deeper extension comparison, use our guide to Australian domain names. When you are ready to check availability, go to Find a Domain.
Step 1: Choose the extension before you search
For a business trading in Australia, start with .com.au. Customers recognise it, and the commercial eligibility rules are why it still carries trust. If the matching .au is free, register that as well and point it at the same site. They are two licences. Buying one does not reserve the other.
.net.au is fine if you already use it. It is rarely where we would start for a new brand if the .com.au is available. .com is useful if you sell overseas or want the global version of the name protected. The full ranking and eligibility detail sits on Australian Domain Names — this post is the buyer’s checklist, not the comparison essay.
Step 2: Check you can actually register it
Australian namespaces are not open like a generic .com. auDA runs the rules.
- .com.au / .net.au — generally for Australian commercial entities. The name needs a connection to the business, an acronym, a trade mark, or what you sell. Most businesses use an ABN or ACN. A registered Australian trade mark can count in some cases.
- .au — needs an Australian presence. You do not always need an ABN. You do need the registrant details right.
If the connection between the business and the domain is not obvious, ask before you pay. Getting stuck at checkout with a cart full of hope is a waste of an afternoon. Official policy lives on auDA’s licensing rules and the Australian presence requirement.
Step 3: Search availability and compare the obvious variants
Search the brand you can say on the phone. If the business is Example Plumbing, look for exampleplumbing.com.au — not a keyword-stuffed alternative nobody will spell. Check .com.au and .au in the same pass. If both are free and the second year will not hurt, take both.
You can search live pricing and availability on Find a Domain. Registration prices for the common Australian extensions are also listed on the Australian domain names pricing table. Renewal is confirmed in the cart before you pay.
Step 4: Register it in the business’s name
A developer or agency can complete the purchase for you. The registrant still needs to be the business, with the right eligibility details. Do not leave your main domain in a freelancer’s Gmail account or a staff personal login.
Losing a website rebuild is recoverable. Losing the domain takes the site and the email with it. Keep renewals, DNS and support somewhere you can still access in two years. That is the quiet reason businesses eventually transfer a domain into the same account as their hosting.
Step 5: Point DNS only when you are ready
Registering the domain and hosting the website are separate. You can buy the name now and leave DNS alone until the site is ready. When you do connect hosting, change nameservers or records deliberately. A transfer between registrars does not move the website unless the nameservers change too.
If you already own the name elsewhere and want domains, DNS, hosting and tickets in one Australian account, start on Transfer a Domain. Unsure whether it is safe? Ask us to check DNS first.
What it usually costs
Australian domain prices sit in AUD and move with the registry and any promo. On HSJ Host, the common .au extensions are typically in the same from-price band as each other, with .com higher. Treat the live table as the current registration figure and confirm renewal in the cart. There is no permanent purchase — domains renew on a term, usually yearly.
Cheapest is not the same as best. A $2 first-year domain that renews at a nasty rate, or lands in an account you cannot access, is the expensive option.
Quick answers people ask before they buy
Do I need an ABN to buy a domain?
For most .com.au registrations, businesses use an ABN or ACN. It is not the only path, and .au has an Australian presence rule rather than a hard ABN rule. If you are unsure, check before checkout rather than guessing.
Can I buy a domain name permanently?
No. You license it for a registration period and renew to keep it. Miss renewals and the name can go into a redemption process and eventually become available to someone else.
Is .com better than .com.au?
For a business that mainly trades in Australia, we would still start with .com.au. Add .com if you need the global name or sell overseas. They are separate registrations — same story as .com.au versus .au.
The short version
- Pick .com.au first. Take .au alongside it if you can.
- Confirm eligibility before you pay.
- Search a name people can say on the phone.
- Register it under the business, not a personal account.
- Point DNS when the site is ready — not before you understand what will move.
