How to Choose a Domain Name for an Australian Business
Your domain is the one part of your digital setup you can never really replace. Here is how to pick the right ending, stay inside the auDA rules, avoid the spelling traps, and make sure the licence is in your name and not someone else’s.
For an Australian business, register the .com.au. It is the address customers assume you have, and it needs an ABN, ACN or matching Australian trade mark. Pick your brand name over a keyword phrase, keep it short enough to say over the phone, and register it in your own name, not your agency’s. Expect $15 to $30 a year excluding GST.
Domain choice costs about $20 to make and thousands to undo. Everything attaches to it: your email, your signage, your Google Business Profile, every backlink you earn. We have moved clients off a bad domain before, and it eats a month of careful work plus a dip in traffic while search engines catch up.
What is the difference between .com.au, .au and .com?
Three endings matter here and they are not interchangeable. A .com.au is the default for a business trading in Australia and carries the most instinctive trust with local buyers. The shorter .au namespace has only existed since March 2022, so plenty of people still read it as a typo. A plain .com is the global default: fine if you sell overseas, weaker as a local signal, available to anyone on earth.
| Ending | Best suited to | Australian presence needed | Cost per year (ex GST) | Worth knowing |
|---|---|---|---|---|
| .com.au | Any business trading in Australia | Yes | $15 to $30 | The safe default. Strongest local trust signal. |
| .au | Brands wanting a shorter address | Yes | $15 to $30 | Priority allocation closed in 2022. First in, first served now. |
| .net.au | Defensive registration alongside .com.au | Yes | $15 to $30 | Rarely worth using as a primary address. |
| .com | Exporters, software, online-first brands | No | $15 to $25 | Anyone worldwide can register one. No geographic signal. |
| .org.au | Charities, associations, clubs | Yes, non-commercial | $15 to $30 | Sends the wrong message for a trading business. |
| Novelty endings (.plumbing, .digital, .io) | Almost nobody in local services | No | $5 first year, $40 to $90 after | Cheap to start, poor recall, high renewals. |
If you can only justify one domain, make it the .com.au. Google ties it to Australia automatically, a small free advantage when somebody in Parramatta searches for a service nearby. The .au direct option is tempting, since shorter is genuinely better on a van door, but say ‘smithplumbing dot ay you’ to anyone over fifty and watch the pause. Our view: .au as a secondary domain you redirect, .com.au as the one on the invoice.
Who is actually allowed to register a .com.au or .au domain?
You need an Australian presence. In practice that means an active ABN, an ACN, an ARBN, a business name registered with ASIC, an incorporated association, or an Australian trade mark application or registration. No Australian presence means no .com.au. Registrars verify this at registration and auDA can audit a licence afterwards.
- An ABN or ACN covers the overwhelming majority of registrations. A sole trader with an active ABN qualifies the same as a company.
- Registering under an Australian trade mark instead means the domain must be an exact match to the words in that mark, ignoring punctuation and words like a, the and of.
- Overseas companies without an ABN need an ARBN or an Australian trade mark. There is no third path.
- It is a licence, not ownership. You hold the right to use the name while you remain eligible and keep paying.
One old myth deserves burying. Under the auDA licensing rules that took effect in April 2021, a .com.au registered on the strength of an ABN no longer has to match your business name; the close and substantial connection test is gone. If your entity is Smith Family Trust and you want bluemountainsroofing.com.au, you can have it. The exact match rule only bites when a trade mark is your sole claim to Australian presence.
The .au direct namespace opened on 24 March 2022 with a six month priority window for anyone already holding the matching .com.au. That window closed on 20 September 2022 and is not coming back. If you never claimed yours it is first in, first served now, and somebody else may already hold the .au version of your name.
Lose your eligibility, lose your domain. Cancel the ABN, wind up the company or let the trade mark lapse, and the licence under your .com.au becomes invalid at renewal. This catches out businesses that restructure. If you shift from a sole trader ABN to a company ACN, update the registrant details with your registrar at the time.
Should you use your brand name or a keyword in the domain?
Brand name, nearly every time. Exact match keyword domains like sydneyemergencyplumber.com.au once carried a real ranking advantage, but Google’s 2012 update targeting low quality exact match domains took most of it away and what remains is small enough to ignore. You keep a slightly better click-through rate. You give up the ability to ever be anything other than a Sydney emergency plumber.
A keyword domain also locks in a service and a suburb at the moment you know least about your own growth. We watched a client trade for eleven years under a domain naming a suburb they left in year three. If your preferred name is taken, adding group, co or your city reads far better on an invoice than a stuffed keyword.
What makes a domain name hard to live with?
Apply the phone test. Say the domain out loud to somebody who has never seen it written and ask them to type it. If you find yourself spelling part of it, or saying ‘that’s with a hyphen’, or ‘no, the number four’, it will quietly cost you enquiries every week for as long as you own it.
- Hyphens are the worst offender. Nobody says them out loud, everybody forgets them, and the version without usually belongs to a competitor.
- Numbers create the same fork. Is it 4 or four? You will answer that question forever.
- Words with two accepted spellings cause endless grief: colour and color, jewellery, tyre, grey, practice versus practise.
- Keep it under 20 characters before the ending. Long names get truncated in Google Ads and look cramped on a ute.
- Read the string joined up rather than as separate words. Two harmless words can form something unfortunate once the spaces go.
- Skip the word Australia. The .com.au already says it.
What should you check before you register a domain?
Four checks, ten minutes, all free. Do them before you spend a dollar on logos or signage, because a trade mark conflict discovered after the vehicles are wrapped is an expensive lesson.
- Australian Trade Mark Search at IP Australia. Search your proposed name and anything close to it. Owning a domain gives you no protection against a registered mark, and under the .au dispute resolution policy a mark owner can complain and have the domain transferred.
- ASIC Connect and ABN Lookup. Check the business name is free and see who already trades under something similar. If ASIC will not register the name, keep thinking.
- Search the exact name in quotes and check the social handles. Free as a domain but taken everywhere else is only half available.
- Look up the .au, the .net.au and the .com while you are there.
None of that is legal advice and we are not lawyers. If your search turns up a mark in the same class as your business, spend an hour with an IP solicitor before you commit.
How much does a domain name cost in Australia?
A .com.au runs $15 to $30 a year excluding GST from a mainstream Australian registrar. A .com sits around $15 to $25. Some charge $60 for the identical product, others sell the first year at $2 then renew at $45, so read the renewal price before you get excited. You are really paying for a control panel you can log into and a support line that picks up.
| Item | Typical cost (ex GST) | Notes |
|---|---|---|
| .com.au or .net.au registration | $15 to $30 per year | Available in one to five year terms |
| .au direct registration | $15 to $30 per year | Same eligibility rules as .com.au |
| .com registration | $15 to $25 per year | Watch for $2 first year offers |
| Premium or aftermarket domain | $500 to $50,000 plus, one-off | Someone already owns it and has set a price |
| Transfer to another registrar | $0 to one year’s fee | Usually adds a year to your expiry |
| DNS hosting | Normally $0 | Included by the registrar or your host |
Registering for ten years does nothing for your rankings. Google does not use registration length as a signal, and the old advice about a long term looking more legitimate is out of date. Register for several years if it stops you forgetting to renew. Most registrars will put the domain on the same invoice as your Australian web hosting.
Who should hold the domain registration?
You. The registrant should be your legal entity, with your ABN, at an email address you control. Not your web designer’s name. Not a staff member’s personal Gmail. Not an agency reseller account only they can log into. Under the auDA rules the registrant is the licence holder, so whoever is named there holds the asset, not whoever paid for it.
The failure looks the same every time. A supplier relationship goes cold, and the business discovers the domain sits inside a reseller account belonging to someone who has stopped taking their calls. No transfer code, no login, renewal due in six weeks. We pick up clients in this position several times a year and it is entirely avoidable.
Ask for three things in writing before anyone registers a domain for you: the registrar’s name, a login to that account in your own name, and confirmation that the registrant is your entity and your ABN. A supplier who will not hand those over is telling you something about the rest of the relationship.
How should you handle multiple domains and redirects?
Choose one primary domain and 301 redirect everything else to it. One website, one address in the search index. Do not copy the site onto each domain hoping to rank twice, because it splits your authority and search engines will pick one anyway.
- Register defensively but stay sensible: the .com.au as primary, the .au, the .com if it is cheap, and a common misspelling if your name attracts one. Past that you are donating to registrars.
- Use a proper 301 at the hosting or DNS level. Avoid anything sold as forwarding with masking, which hides the real address inside a frame and reads as deceptive.
- After a rebrand, keep the old domain and its redirect live for at least three years. Your existing backlinks all point there.
- Every redirecting domain still needs a valid SSL certificate, because people type https out of habit.
- Pick one canonical version, www or bare, and redirect the other. Same with http to https.
- Send email from the primary domain only. Mail from a redirect domain fails authentication and lands in spam.
Redirects are where most domain moves come unstuck. If you would rather not touch DNS records, a decent host does this as part of the plan: our managed hosting and domain service covers redirects, certificates and renewals. Our other WordPress and hosting guides go deeper on what sits behind the name.
One thing to take away: the domain is the only asset in your setup that cannot be recreated. Sites get rebuilt, hosting swaps over in an afternoon, logos get refreshed. The name people type is yours alone, and only if the paperwork says so.
Common questions
Can I change my domain name later without wrecking my rankings?
Yes, if you do it properly. Map every old URL to its new equivalent with 301 redirects, keep the old domain registered and redirecting for at least three years, and lodge a change of address in Google Search Console. Expect a dip for two to eight weeks while things settle. Most sites recover fully, but nobody can guarantee it, so only move when there is a real reason.
Does my domain have to match my registered business name?
Not since April 2021. If your Australian presence comes from an ABN or ACN, you can register any available .com.au regardless of what your entity is called. The exception is registering on the basis of an Australian trade mark alone, where the domain must exactly match the words in that mark. Matching your trading name is still smart for recognition, it is just no longer a rule.
Is it worth paying thousands for a premium domain someone else owns?
Occasionally. If the name is short and obvious and you plan to spend on radio, print or vehicle signage, a $5,000 domain people can spell first go pays for itself in reduced friction. For most local service businesses it does not, and that money buys a lot of Google Ads. Get an independent view on value before you negotiate, and never let the seller know how badly you want it.
Should I register the .au version if I already have the .com.au?
Usually yes. At $15 to $30 a year it is cheap insurance. Register it, redirect it to your main site, forget about it. The risk you are covering is a competitor or an opportunist grabbing the short version of your name and confusing your customers. If the .au is already held by someone unrelated, it is rarely worth fighting over unless they are trading on your reputation.
What happens if I forget to renew my domain?
It stops resolving, so your website and your email both go dark, usually within hours. Australian domains then sit in a grace period of roughly a month where you can still renew, sometimes with a late fee. After that the name is released and anyone can take it, and businesses exist purely to catch expiring domains with traffic. Automatic renewal plus a valid card on file avoids the whole thing.
Can someone take my domain if they own a trade mark on the name?
They can try, and they often succeed. The .au dispute resolution policy lets a trade mark owner file a complaint arguing the domain is confusingly similar to their mark and was registered in bad faith. If the panel agrees, the domain is transferred to them. This is why the IP Australia search comes before the registration, not after the signage. Registering a domain confers no trade mark rights at all.
Do I need a separate domain for each service or location I offer?
No, and it usually backfires. Separate domains mean separate sites to build, host, secure and update, each starting from zero authority. One strong domain with dedicated pages for each service and suburb will outrank a scatter of thin microsites almost every time. The exception is a genuinely distinct business with its own brand, staff and customers, which is a different decision entirely.
Not sure who actually owns your domain?
Send us the address and we will look up the registrant, tell you straight whether the licence is in your name, and explain what it would take to bring it back under your control. No lock-in contracts, Australian support, building and looking after websites since 2004.
