Country-Code Domains in Oceania

Updated October 2026

27 country-code extensions belong to Oceania. Here they are with their registries and a summary of who can register.

Country codes in Oceania

Oceania's country-code domains include Australia's .au and New Zealand's .nz, plus many small Pacific island nations whose extensions became global brands, such as .tv (Tuvalu), .fm (Micronesia), .ws (Samoa), .to (Tonga) and .nu (Niue). For several of these islands, domain income has been a meaningful source of revenue.
