.au Domain Administration Limited (auDA) is a not for profit organisation that works with a range of stakeholders including industry, government and the Australian and international community to develop and administer the rules for domains in the .au country code Top Level Domain (ccTLD).

The .au ccTLD is part of Australia’s critical infrastructure, and we have been endorsed by the Commonwealth Government to ensure it is a safe, accessible and trusted Australian public asset for all internet users. We also represent Australia’s interests internationally and have an agreement with the Internet Corporation for Assigned Names and Numbers (ICANN) – the international body covering ccTLDs.

Our purpose is to manage and maintain a secure, resilient and stable Domain Name System (DNS) and we do this by:

  • developing and implementing domain name policy;
  • licensing 2LD registry operators and accrediting and licensing registrars;
  • implementing consumer safeguards and facilitating dispute resolution;
  • representing Australia’s domain name interests internationally;
  • technical management of the .au zone file; and
  • ongoing innovation and improvement.

We recognise the critical importance of our role and the work we do, and we hold ourselves to high standards of corporate governance and integrity.

The auDA Constitution is the main source of information about how we operate as a company, including appointment and duties of Board Directors, membership of auDA and our advisory committees.
