Australia
Overview
Direct registration under Australia's country code became possible only in 2022; until then applicants used second-level namespaces such as .com.au. auDA operates the registry, which holds approximately 4.3 million domains. Eligibility requires a demonstrable Australian presence — an ABN, an ACN, or citizenship — leaving the namespace closed to foreign registrants without local standing. The 2022 change gave Australian businesses a shorter option alongside the established second-level forms rather than replacing them.
