RDAP availability is taken from the IANA RDAP bootstrap file published on 2026-09-16; WHOIS server and delegation year from the IANA root zone database. Registry policies change: check the registry's own policy before relying on an eligibility rule.

What is .au?

.au is the country-code top-level domain of Australia, overseen by auDA. Most Australian names sit in second-level zones such as .com.au, .net.au and .org.au; direct registration under .au (example.au) was introduced in 2022.

Who can register it

Every .au registrant must have an Australian presence, for example an Australian citizen or permanent resident, a company registered in Australia, or the owner of an Australian trade mark (with conditions). Registrars verify this against official identifiers such as an ABN or ACN.

WHOIS, RDAP and privacy

An RDAP service for .au (rdap.cctld.au) is published in the IANA RDAP bootstrap file. OrbitProbe reads registration data from it first, as structured JSON: registrar, creation and expiry dates, EPP status codes and nameservers. For ccTLDs, what is published is decided by the registry and local law rather than by ICANN, so output differs from one extension to the next. Most registries do not show the personal data of individuals in public output. OrbitProbe only ever shows the organisation name and country.

FAQ

Who can register a .au domain?

Every .au registrant must have an Australian presence, for example an Australian citizen or permanent resident, a company registered in Australia, or the owner of an Australian trade mark (with conditions). Registrars verify this against official identifiers such as an ABN or ACN.

How do I run a WHOIS lookup for a .au domain?

Type the name, in the form example.au, into the form on this page. OrbitProbe first queries the RDAP service of the .au registry (rdap.cctld.au). The result shows where the data came from and when it was observed.

Does .au support RDAP?

Yes. The IANA RDAP bootstrap file dated 2026-09-16 publishes rdap.cctld.au for .au. The classic WHOIS server is whois.auda.org.au.
