Choosing a domain name for an Australian business

Choosing domain names: what actually matters before you register

A name that matches how customers already refer to the business, or plainly describes what it does, outperforms cleverness in the long run. People cannot type a domain they cannot remember. A name that needs to be spelled out on the phone is a small tax paid on every single referral. For an Australian business considering .com.au or a bare .au, naming is not only a memorability question either. The name also has to relate to the business in a way auDA’s rules actually recognise.

What makes a good domain name memorable, in general

Shorter is generally better, but not at the cost of clarity. A shortened or invented word that needs explaining defeats the purpose of a memorable address. Hyphens and numbers both reduce memorability. They also raise the chance of a mistyped visit going to a competitor or a squatted alternative instead, so are worth avoiding unless there is no other option. A name close to an existing competitor risks customer confusion at best, and a trade mark dispute at worst.

Checking trade marks and government registers before committing to a domain name, not after

A quick search of the ASIC business names register and IP Australia’s trade mark search, before settling on a name, is a cheap check against an expensive later dispute. Registering a domain does not itself grant any trade mark rights. A name that infringes an existing mark can be lost regardless of how long it has been used as a domain. Do this before falling in love with a specific name, not after a business card has already been printed with it.

Why an Australian eligibility test changes the naming question

Unlike a .com, where almost any available string can be registered by almost anyone, .com.au and a bare .au both require the domain to be a Match or a Synonym of the registrant’s own legal name, a registered business name, or a trade mark they hold — the current test, in force since 12 April 2021, is set out fully in .com.au versus .au versus .com. This means an appealing, purely descriptive or invented name that has nothing to do with the business’s actual registered name may simply not be available to that business under the .au namespaces, however available it looks in a registrar’s search box.

Aligning the name with what is actually registered

Because eligibility is tested against a registered business name, a trade mark, or a legal entity name, check that the name intended for the domain matches — or is a genuine synonym of — what is actually registered with ASIC or IP Australia. Do this before assuming a domain search result showing the name as “available” means it is available to this specific business. A mismatch here is one of the more common, avoidable reasons a registration gets rejected or later challenged.

What to do if the ideal name does not clear the test

Register a business name or seek a trade mark that matches the intended domain, if that genuinely is the business’s actual trading identity. This is a legitimate and common path, not a workaround. Or choose among the names the business is already eligible for under its current registrations — usually the faster route. A .com carries no such test at all. It is worth holding alongside a .com.au or .au, specifically to stop an unrelated party registering the matching global name, even where it is not the business’s main address.

Plurals, abbreviations and near-misses in domain names

A business registering the singular form of its name is often wise to also consider the plural, or a common abbreviation customers actually use. A competitor or unrelated party registering the close variant can create genuine customer confusion, even without breaching eligibility. This is a judgement call about budget versus protection, not a rule. Make it deliberately rather than by default.

Checking pronunciation and spelling out loud

A name that reads clearly on a page can still be genuinely ambiguous spoken aloud — over the phone, in a radio ad, at a networking event. Say the intended domain out loud to someone unfamiliar with the business, and ask them to spell back what they heard. It is a quick, low-cost test. It catches a surprising number of otherwise-appealing names before they become a permanent, minor tax on every verbal referral.

Getting a second opinion on the business name before committing

Ask a handful of people unfamiliar with the business to read the proposed name back and say what business they would guess it belongs to. It is a cheap, genuinely useful test that a business too close to its own naming decision often cannot run on itself.

Social media handle availability, briefly

Check whether a matching handle is available across the social platforms a business actually plans to use, at the same time as the domain check. Consistent naming across a domain and social profiles cuts the small, ongoing confusion of a business known by one name online and a slightly different one everywhere else.
