auDA Registrar ISS logo2017 .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 theTelecommunications 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.  auDA achieves this through the technical management of the primary and (multiple) secondary name servers that make up part of the .au Domain Name System infrastructure.
