What a domain search actually tells you
A domain name availability check that comes back “unavailable” is not the end of the story - it is the start of a more useful investigation.
Run a domain owner search on any unavailable domain through a WHOIS tool (lookup.icann.org or whois.ausregistry.com.au for Australian ccTLDs). You will see the registrant name, registration date, and expiry date. A domain expiring in the next few months is worth watching. Backorder services like DropCatch and NameJet let you place a claim on a domain so you are notified - and entered into a drop-catch auction - the moment it becomes available again.
Domain history matters as much as current availability. Domains previously used for spam, cloaking, or link farms can carry email reputation penalties and search engine baggage. Before registering any domain with a history, run it through the Google Transparency Report (transparencyreport.google.com) and the Spamhaus blocklist (check.spamhaus.org). A clear availability result tells you nothing about what the domain was used for before.
Trademark status is a separate check from domain availability. A domain can be fully open to register while the underlying name is protected by an existing trademark in your category. Search IP Australia’s trade mark database at search.ipaustralia.gov.au before committing to any name. A registered trademark holder can challenge your domain through UDRP or Australian court processes - and they do not need to hold the domain themselves to do it.
For Australian businesses, there is one more layer: eligibility for .com.au. The domain may be available, but you may not qualify to register it. auDA (the .au Domain Administration) requires that your domain closely and substantially correspond to your registered business name, company name, or trademark. Checking availability without checking eligibility is a common time-waster.
How to search for domain names effectively
Starting from scratch rather than checking a specific name? The domain name generator surfaces fresh ideas, or if you haven’t settled on a business name yet, start with the business name generator.
Search your exact intended name first, then branch into systematic variations. If “tradecraft.com.au” is taken, check “tradecrafthq.com.au”, “tradecraftapp.com.au”, and “gettradecraft.com.au” in the same session. Checking variations one at a time across different tools is slow - and availability can change while you work.
NameCraftr checks .com, .com.au, and .au in real time as it generates suggestions. That means every result you see has already been verified across all three extensions simultaneously. You are not building a list and then running a separate sweep. Searching all three at once also matters because Australian businesses typically need both the ccTLD for local trust and .com for international reach - seeing that a name is available across all three in one pass significantly narrows your shortlist faster.
Run your shortlist through these tests before committing:
- Check .com.au eligibility before anything else. If your intended trading name does not closely match a business name registered with ASIC or a company name registered with ASIC, you cannot register it as .com.au. Verify this against the ASIC Business Names Register (connectonline.asic.gov.au) before investing in the name.
- Say it aloud to someone without spelling it. Australian customers share business names verbally at networking events, through referrals, and in conversation. If the name requires spelling clarification every time, it is the wrong name.
- Search the name on Google - not the domain, the name itself. Check for existing businesses, unintended meanings in other languages, or associations that could create confusion in the Australian market.
When .com.au is unavailable and the holder appears to be a dormant or unrelated business, check whether the registration is close to expiry through the WHOIS record. If there is still years left on the registration and the holder is actively using it, choose a different name - pursuing an acquisition for a .com.au is rarely worth the cost and complexity compared to finding a genuinely available alternative.
After the search: registering and securing your domain
When NameCraftr surfaces a name that is available across .com, .com.au, and .au, register all three immediately. Do not announce the name first, do not wait until your website is ready. Domain squatters monitor registrar search traffic and can register a name within hours of you checking it.
Register .com.au and .au through an auDA-accredited registrar - Crazy Domains (crazydomains.com.au), VentraIP (ventraip.com.au), or NetRegistry (netregistry.com.au) are the main Australian options. Prices typically range from $15 to $30/year for .com.au and .au. You will need your ABN during registration and the domain must match your registered business name.
Register .com through Namecheap ($10-12/year) or Cloudflare Registrar (cloudflare.com/products/registrar, $9.15/year with no markup). Avoid promotional first-year pricing that jumps significantly on renewal.
Set these up immediately after registering:
- Auto-renewal on every domain - losing a domain to expiry is entirely avoidable and catastrophic. Your email stops working, your website goes dark, and the domain becomes open to anyone.
- WHOIS privacy on .com - keeps your personal contact details out of public WHOIS records. Check what your registrar offers for .com.au and .au - auDA has its own WHOIS policies for ccTLDs.
- Domain lock - prevents unauthorized transfers. Confirm it is enabled at your registrar.
If you plan to trademark your business name in Australia, file with IP Australia (ipaustralia.gov.au) as soon as your domains are secured. Trademark rights run from the filing date, not the domain registration date.
Common domain search mistakes
Checking availability without checking .com.au eligibility. Founders regularly find an available .com.au, start building a brand around the name, and then discover they cannot register it because their trading name does not match a registered business name closely enough. The eligibility check takes five minutes on the ASIC register - do it first.
Registering .com.au but not .au. Since the short-form .au extension launched in 2022, many businesses secured .com.au without registering the matching .au. They are separate registrations requiring separate purchases. If both are available, register both immediately - squatters specifically watch for .com.au holders who have not also claimed .au.
Skipping .com because you are focused on the Australian market. Even businesses that only serve Australia need to consider who might register .com. A competitor, a squatter, or a business from another country using the same name can create lasting confusion. Registering .com defensively costs $10-15/year and prevents that problem entirely.
Treating availability as the only check. An available domain with a spam history or a trademark conflict can cost you far more to resolve later than finding a clean name would have cost upfront. Always run the full sequence: a whois domain name search for ownership history, Spamhaus, Google Transparency, IP Australia trademark search.
Registering and then forgetting to renew. Domain expiry is one of the most avoidable business crises. Enable auto-renewal on every domain you register - the annual cost is trivial compared to the disruption of losing a domain you built your entire online presence around.
