Guide · .com.au domain check
Bulk .com.au domain check for a whole shortlist of names
Naming a business? Check every idea across .com.au and .com in one run, and see which names already clash with an app or a trademark.
The problem
Most bulk domain checkers are built for .com
Registrar bulk search tools are good at .com but are designed to sell you domains, and many treat .com.au as an afterthought. When you're shortlisting names for an Australian business, you want the .com.au and the .com answer side by side, from the registry itself, before you fall in love with a name.
This checker queries each registry over RDAP (the official successor to WHOIS) and confirms with a DNS lookup. A name with no registry record is reported as likely unregistered, never as guaranteed available: premium, reserved or just-dropped names can still be unavailable, so always confirm at a registrar before you rely on it.

How to check .com.au availability for many names

.com, .com.au, .io, .ai, .co and .net are checked by default; you can change the list.

Review
Read the risk rating
Each name gets a rating with plain-English reasons, App Store name clashes, live US trademark counts, and a ready-made IP Australia trade mark search link.
Eligibility
Can you register the .com.au once it's free?
Availability is only half of it. Under auDA's licensing rules, a .com.au needs an Australian presence and a commercial entity (in practice usually an ABN or ACN), and the name must be connected to you: typically a match or abbreviation of your company or business name, or your Australian trade mark. A .au direct name only needs an Australian presence. auDA is reviewing the com.au allocation rules in late 2026, so check auda.org.au for the current wording before you register.
Tip: if your preferred .com.au is free but doesn't match your registered business name yet, registering the business name first may be the cleanest path.
FAQ
Frequently asked questions
How many names can I check at once?
As many as you like: paste 5 or 5,000. You pay US$3 per 1,000 names checked, plus a little Apify compute.
Is "no record found" the same as available?
No. It means the registry has no record and the name has no DNS delegation, so it is likely unregistered. Confirm at a registrar before relying on it.
Does it check Australian trade marks?
It gives you a direct IP Australia search link for every name. Live US trademarks are checked automatically.
