Domain names

Every internet location such as a webpage has a unique address, and that address falls under a domain name – for instance, ‘’.

The not-for-profit .au Domain Administration (auDA) oversees the operation and management framework of the .au domain of the internet. auDA is an independent body endorsed by the Australian Government as the appropriate entity to administer Australia’s country code Top-Level Domain (ccTLD)—the .au domain—on behalf of Australian internet users.

The domain name system (DNS) underpins the operation of the internet. The DNS is the global database that translates website names (such as into computer-readable internet protocol (IP) addresses. auDA manages the .au portion of the DNS.

auDA’s Terms of Endorsement

auDA is independent from the Government, however it has been endorsed as the .au manager since 2000. auDA’s current Terms of Endorsement provide the Government's formal endorsement of auDA, with this endorsement subject to auDA's compliance with the Government's expectations.

auDA develops and implements .au domain policies and allocates (or licences) .au domain names to users who meet its eligibility criteria, for up to five years.

auDA is solely responsible for making policy on .au domain matters, but it is required to support the multi-stakeholder model of internet governance and consult widely with Government and the community prior to making a decision. From time to time the Department provides feedback to auDA on policy matters to inform it’s consideration of an issue. View:

2021 Review of the Terms of Endorsement for auDA

In 2017-18, the former Department of Communications and the Arts undertook a review of auDA's governance arrangements (see link below for more information).

This further review was completed in 2021, and included a public consultation process.

Following the recommendations of the review, updated Terms of Endorsement have been issued:

The new Terms are based on a set of core principles, including:

  • Effective engagement with the Australian Government
  • Supporting trust and confidence in .au

  • Supporting fair and transparent multi-stakeholder engagement
  • Supporting a membership structure that reflects the diversity of the Australian community
  • Maintaining effective governance processes that are transparent, accountable, support effective decision-making and promote the interests of the Australian community
