.com.au vs .com: Which Domain Is Better for SEO?

Quick answer: For a business that serves only Australia, a .com.au is usually the better choice: it tells Google and customers the site is Australian, and holding one requires an Australian presence such as an ABN. A .com can still rank well here and suits businesses selling in several countries, but it has to prove its Australian focus through content, links and hreflang.

Domain extensions attract more folklore than most SEO topics. Some owners treat a .com.au as a ranking boost in itself; others assume a .com looks bigger and more international. Neither belief holds up. The extension is one signal among many, and the decisions that matter more are about eligibility, where your customers are, and how carefully you move if you change. Our SEO basics cover the signals that outweigh the domain.

Does a .com.au domain help you rank in Australia?

It helps Google understand who the site is for; it won't lift weak pages above strong ones.

A country-code domain such as .com.au is a strong signal that a site targets Australia. A .com is generic, so Google works out its audience from everything else: prices in Australian dollars, an Australian address and phone number, local spelling, links from Australian sites, a Google Business Profile and hreflang annotations. Google has also retired Search Console's international targeting report, so there is no longer a setting that tells it "this .com is for Australia". The content has to carry that message.

There is a human side too. Many Australians read .com.au as a sign that a business is local, which can help when a searcher is choosing between results.

What are the eligibility rules for .com.au and .au direct?

Both need an Australian presence; .com.au also needs a link between the name and your business.

Per auDA's licensing rules, Australian presence covers registrants such as Australian citizens and permanent residents, Australian-registered companies, ABN holders and owners or applicants of an Australian trade mark. For a .com.au, the name must also be an exact match, abbreviation or acronym of your name or trade mark, or otherwise closely and substantially connected to you, for example a service you provide.

That last route is under review. In August 2026, auDA's board approved in principle a recommendation to remove the "close and substantial connection" route for new .com.au registrations, subject to public consultation, and auDA has said existing licences would not be affected. Check the current rules before registering a name that describes a service rather than your business.

.au direct, such as yourname.au, has been available since 24 March 2022 and requires only an Australian presence, with no name connection test.

When does a .com make more sense for an Australian business?

When your market is bigger than Australia, or your .com already carries years of rankings.

• You sell in several countries. One .com with /au/, /uk/ and /us/ folders and hreflang (en-AU, en-GB, en-US) keeps all your authority on one domain.
• You own an established .com. If it already ranks and earns links, the cost and risk of moving may outweigh the benefit of a local extension.
• Your name is taken as a .com.au. A clear .com beats an awkward .com.au with extra hyphens.

If you stay on .com, make the Australian focus unmistakable: GST-inclusive prices in AUD, your ABN in the footer, an Australian address and +61 number, Australian spelling, and links from local organisations.

Should you also register the matching .au direct name?

Usually, yes. It's cheap insurance against lookalikes and phishing. The priority window for existing .com.au holders closed in 2022, so any unclaimed match is now first come, first served.

Register the .au direct version (and the .com, if you're on .com.au) and point it at your main site with a permanent redirect. Don't run duplicate copies of the site on each domain. Keep every name in your business's registrar account with auto-renew switched on, so a lapsed card doesn't hand your name to someone else.

How do you move from .com to .com.au without losing rankings?

Redirect every old URL to its exact new equivalent, then tell Google, your customers and your ad platforms.

1. Crawl the current site and export every URL, including images and PDFs that earn traffic.
2. Map old to new, one to one. Keep paths identical where you can; never send everything to the homepage.
3. Launch with server-side 301 redirects, then test a sample of old URLs, including ones with tracking parameters.
4. Verify both domains in Search Console, submit the new sitemap and use the Change of Address tool once redirects are live.
5. Update canonicals, hreflang and internal links so the new site never points back to the old one.
6. Update everything outside the site: Google Business Profile, directories, social bios, email signatures, invoices and ad final URLs. Google Ads can disapprove ads whose final URL redirects to a different domain.
7. Keep the old domain registered and redirecting for years, not months. Google suggests keeping redirects for at least a year; we'd keep them indefinitely.
8. Watch Search Console for six to eight weeks for 404s, indexing gaps and traffic dips on key pages.

Expect some fluctuation while Google processes the move. Our checklist for a redesign without losing SEO covers the redirect map in more depth, and the same discipline applies to a domain change.

What about businesses serving Australia from India or overseas?

Without a genuine Australian presence, a .com with clear Australian content is the honest choice.

An overseas company can qualify for .com.au through an Australian trade mark, registered or applied for. Avoid borrowing a friend's ABN or a service that registers the name under someone else's details: auDA can cancel licences that don't meet the rules, and you'd have little control over a domain held in another person's name.

The alternative works well. A .com with an Australia section, AUD pricing, an Australian phone number, contact hours that suit Australian time zones and real local proof can rank and convert. If you later set up an Australian entity, add the .com.au then and migrate carefully. For the advertising side, our guide to reaching Australian clients from India covers targeting and time zones.

Frequently asked questions

Is .com.au better than .com for Google rankings in Australia?

A .com.au gives Google a clear country signal, which helps for Australian searches. It doesn't override content quality, links or relevance, so a strong .com can outrank a weak .com.au. For an Australia-only business, the .com.au is usually the simpler path.

Do I need an ABN to register a .com.au?

You need an Australian presence, and an ABN is the most common way small businesses meet it. An Australian company number, citizenship or permanent residency, or an Australian trade mark also qualify. The name must also connect to your business under auDA's rules.

What is a .au direct domain?

It's a domain ending simply in .au, such as yourname.au, available since March 2022. It needs an Australian presence but no connection between the name and your business.

Will switching to .com.au hurt my SEO?

A careful migration with one-to-one 301 redirects and Search Console's Change of Address tool usually causes only a temporary dip. Rankings suffer when redirects are missing, sent to the homepage or removed too soon.

Can an overseas business register a .com.au?

Only if it has an Australian presence, most often through an Australian trade mark or a registered Australian entity. Otherwise, use a .com with clear Australian content.
