Which domain extension is right for an Australian website?
Australia has a tiered domain system and the right choice depends on who you are serving.
.com.au is the most trusted extension for Australian websites. It signals local presence to visitors and search engines and is strongly preferred when your audience is primarily Australian. To register .com.au, you need an ABN (or ACN) and the domain must closely correspond to your registered business or company name.
.au (the shorter form, introduced in 2022) gives Australian websites a more concise option with the same eligibility requirements as .com.au. It is shorter and increasingly accepted, particularly in tech and consumer brands. If both .com.au and .au are available for your name, register both.
.com remains essential for any Australian website with international visitors, overseas clients, or global ambitions. International audiences, overseas press, and global partners default to .com. For websites serving both Australian and international audiences, .com.au for local trust and .com for international reach - redirecting one to the other - is the standard approach.
NameCraftr checks .com, .com.au, and .au availability in real time for every suggestion, or run any shortlisted name through the standalone domain name checker once you’ve narrowed it down. You can see your options across all three extensions simultaneously.
How to find the right website name with the generator
Naming a company rather than a website specifically? The domain name generator covers that broader case, or if you haven’t settled on a business name yet, start with the business name generator.
NameCraftr, a free AI name generator, produces better results with a specific brief. Describe your website by what it does and who it serves - not just the category. “Australian travel blog for solo female travellers exploring Southeast Asia on a budget” generates more distinctive and available suggestions than “travel blog”. Specificity also tends to surface names that are easier to register as .com.au because they are more distinctive.
When evaluating suggestions:
- Say it aloud without spelling it. If the other person asks you to spell it, that name will require extra effort every time it is shared verbally in conversation, referrals, or media mentions.
- Check all three extensions. NameCraftr shows .com, .com.au, and .au availability together. A name available across all three is worth prioritising.
- Check .com.au eligibility. Your domain must closely and substantially relate to your registered business name. If you are trading under a nickname or abbreviation, make sure the matching business name is registered with ASIC before trying to register the domain.
- Google the exact name. Check for existing websites, businesses, or associations in Australia and internationally that could create confusion.
After the generator: securing your Australian website name
Once you have a name you want:
- Register .com.au and .au immediately through an auDA-accredited registrar (Crazy Domains, VentraIP, Netregistry, GoDaddy AU). You will need your ABN and the domain must correspond to your business name.
- Register .com at the same time if available. Even if you primarily use .com.au, owning .com prevents others from creating confusion.
- Set up auto-renewal on every domain. Domain expiry is an entirely avoidable problem - you lose email, your site goes dark, and the name becomes available to anyone.
- Enable WHOIS privacy on your .com registration. Australian ccTLD registrations (.com.au, .au) through auDA-accredited registrars have their own WHOIS policies - check what your registrar offers.
- Register your business name with ASIC before registering .com.au if they are not already aligned. The eligibility check is strict about the name match, and it is faster to resolve this before purchasing than to discover the problem after.
Common Australian website naming mistakes
Not registering .com.au because you already have .com. Australian visitors instinctively add .com.au when searching for local websites. If someone else holds your .com.au, they capture visitors who were looking for you. Register both extensions from day one.
Overlooking the .com.au eligibility requirement before committing to a name. Founders sometimes develop a website around a name and then discover the .com.au they want requires a business name they have not registered. The name match requirement for .com.au is strict - verify eligibility before committing to any name.
Using hyphens to get around unavailability. If “tastemade.com.au” is taken and you register “taste-made.com.au”, visitors who hear the name will go to the unhyphenated version. Hyphens also look less professional in email addresses and on printed materials. If the clean version is unavailable, choose a different name.
Forgetting to register the .au (short form) alongside .com.au. Since the .au extension launched in 2022, many websites have secured the .com.au but not the matching .au. They are separate registrations with the same eligibility rules. If both are available, register both.
Delaying defensive registrations. Squatters specifically watch for growing Australian websites and register .com for sites that only hold .com.au. Register .com at the same time as your Australian domains even if you do not plan to use it as your primary.
