.au
country-code
The .au domain is Australia's country code top-level domain. It is managed by .au Domain Administration (auDA), a not-for-profit organization based in Melbourne. .au has strict eligibility rules. Registrants must have an Australian presence, such as an ABN (Australian Business Number) or ACN (Australian Company Number), or be a trademark holder or an Australian citizen. Most registrations take place under second-level categories like .com.au, .net.au, or .org.au, each with its own criteria. The domain was first registered in 1986. It went through a redelegation in 2001, which moved management from Robert Elz to auDA. This shift helped open up the namespace for broader Australian community use.
Eligibility and restrictions
Registrants must have an Australian presence (e.g., ABN, ACN, trademark, or citizenship). Specific subdomains have further rules, such as .com.au for commercial entities and .org.au for organizations.
