au Domain Administration Ltd (auDA) is the policy authority and industry self-regulatory body for the .au domain space.

In December 2000, the Australian Government formally endorsed auDA as the appropriate body to administer the .au domain space. The Government holds reserve powers in relation to domain names under the Telecommunications Act 1997.

In October 2001, ICANN recognised auDA as the suitable operator for .au under a Sponsorship Agreement.  As part of that sponsorship agreement auDA is responsible for the management of the .au zone file, ensuring it is accurate, up to date and continuously available.  

Role of auDA

auDA performs the following functions:

  • develop and implement domain name policy
  • license 2LD registry operators;
  • accredit and license registrars;
  • implement consumer safeguards;
  • facilitate .au Dispute Resolution Policy;
  • represent .au at ICANN and other international fora;
  • technical management of the .au zone file; and
  • manage and maintain a secure and stable Domain Name System.
