.au is the internet country code for Australia.

History

The domain name was originally allocated by Jon Postel, operator of IANA to Kevin Robert Elz of Melbourne University in 1986. After an approximately five-year process in the 1990s, the Internet industry created a self-regulatory body called .au Domain Administration to operate the domain. It obtained assent from ICANN in 2001, and commenced operating a new competitive regime for domain registration on 1 July 2002. Since this new regime, any registration has to be ordered via a registrar.

Operation

Oversight of .au is by .au Domain Administration (auDA). It is a not-for-profit organisation whose membership is derived from Internet organisations, industry members and interested individuals. The organisation operates under the consent of the Australian government which has legislative power to decide the operators of electronic addressing in the country.

Policy for .au is devised by policy development panels. These panels are convened by auDA and combine public input with industry representation to derive policy.

The day-to-day operation of the .au registry technical facility is tendered out by auDA. The operator from 2002 to 2006 for many of .au's second-level domains is AusRegistry.

The registry does not sell direct to the consumer, who must register and maintain their domain name via a domain name registrar. After the industry's liberalisation in 2002, there is an active competitive market in registrars with a variety of prices and services.

In 2008 auDA changed its longstanding policy and allowed changes in ownership of .au domains. Although the secondary market was initially slow to take off there have recently been signs of increasing maturity in the .au aftermarket culminating in the record $125,500 sale of investmentproperty.com.au. The auDA ISS is a world-first industry initiative aimed at improving the security of .au registrar businesses, protecting .au registrants and enhancing the overall stability and integrity of the .au domain space. auDA introduced the ISS in October 2013 as a mandatory requirement, and all accredited registrars must be certified as ISS compliant within 24 months. Discount Domain Name services (DDNS), Cheaper Domains and Information Brokers, part of the Total Internet Group, are the first three auDA accredited registrars to achieve ISS compliance.

Registration

It is no longer possible to register directly in the second level of .au (such as mycompany.au). The naming rules for .au require registrations under second-level categories that describe a type of entity. .com.au, for example, is designed for commercial entities. This follows a similar allocation policy to that formerly used in other countries such as the United Kingdom and New Zealand.

Second-level domains

• .com.au – Commercial entities
• .net.au – Commercial entities (historically only ISPs, but the use has been broadened)
• .org.au – Associations and non-profit organisations (historically only for organisations that did not fit in other categories)
• .edu.au – Educational institutions (see Third-level domains, below)
• .gov.au – Governments and their departments (see Third-level domains, below)
• .asn.au – Associations and non-profit organisations
• .id.au – Individuals (by real name or common alias)
• .csiro.au – CSIRO (Commonwealth Scientific and Industrial Research Organisation)

Community geographic domain names

Introduced in 2004, "community geographic domain names" (CGDNs) are intended to be used for "community websites that reflect community interests such as local business, tourism, historical information, culture, sporting groups, local events and news" of a local community. These domains are managed by the .au Community Domains Trust (auCD) on behalf of auDA. The funding of auCD was provided from a ballot of locality names in the .com.au and .net.au domain spaces; previously, any locality with a postcode had been restricted from being registered as a commercial domain name.

CGDNs use the state or territory's common abbreviation as the second level of the domain. For example, a community based in Victoria would receive a domain ending in .vic.au, a Northern Territory community would use .nt.au, and so on. The third level of the domain must be an addressable locality within that state or territory, of the form townname.vic.au. Where a name is duplicated within a state – for instance, between a smaller town, and a suburb of a larger town or city – the locality name may be suffixed with the name of the local government area, town or city to which it is associated (e.g. suburbname-cityname.vic.au).

Holders of CGDNs must be "a legally registered, not-for-profit entity; and [...] representative of the local community for the purpose of holding the domain name licence." In particular, commercial entities and local governments are not permitted to hold a CGDN in their own right; they are however permitted to hold membership in such entities set up to hold a CGDN.

As of November 2009, the auCD site claims 91 active CGDNs across Australia, with a further 115 either approved or awaiting approval.

In addition, a number of temporary CGDN sites were activated for communities affected by the Victorian Black Saturday bushfires of February 2009, run either by "community members" or auCD itself (as a waiver of usual policy). These domains are due to expire at the end of June 2010, unless transferred to an eligible holder.

Third-level domains

The use of .gov.au as a second level domain is for Australian Federal government and for its initiatives, while the use of a third-level domain, being an Australian state, is an identifier that the domain belongs to the relevant state government. The .edu.au is also split up into state-based categories in most cases.

auDA has delegated responsibility of the .edu.au domain to Australian Information and Communications Technology in Education Committee (AICTEC), which formed a specialist sub-committee, .edu.au Domain Administration Committee (eDAC).

Schools use a domain name that reflect their locale, and these state-based third-level domains are managed independently by the states. For example, a school in Western Australia would register schoolname.wa.edu.au. Similarly, replacing the bold part of these domains, Victoria would use .vic, Queensland would use .qld, South Australia would use .sa, Tasmania would use .tas, Northern Territory would use .nt and the Australian Capital Territory would use .act. However, after a change of internet services in Queensland State Schools their domain names were changed from schoolname.qld.edu.au to schoolname.eq.edu.au. This is not the case for private schools in Queensland. Often, domains can even contain a fourth level: for instance, a NSW public school might have the domain schoolname.schools.nsw.edu.au.

Tertiary institutions are typically exempt from requiring state-based distinctions. For example, Edith Cowan University in Western Australia has a domain of ecu.edu.au rather than ecu.wa.edu.au, Monash University in Victoria uses monash.edu.au rather than monash.vic.edu.au. This difference can be associated with states having responsibility for primary and secondary education while the Commonwealth has responsibility for tertiary education; tertiary institutions often having a presence in multiple states.

Queensland	qld.gov.au	eq.edu.au
South Australia	sa.gov.au	sa.edu.au
Tasmania	tas.gov.au	tas.edu.au
Victoria	vic.gov.au	vic.edu.au
Western Australia	wa.gov.au	wa.edu.au
Catholic Education System	N/A	catholic.edu.au

Historic second-level domains

Some second-level domain names are no longer actively used. Whilst registrations are grand-fathered for some, no new registrations are accepted.

• .archie.au – Host of the Archie information service of the early 1990s. Has since been deleted
• .conf.au – Conferences and other short-lived events, now only exists for linux.conf.au.
• .gw.au – Gateways and miscellaneous AARNet routing equipment. Has since been deleted
• .info.au – General information
• .otc.au – A mapping domain for X.400 addresses; was obsoleted by telememo.au. Has since been deleted
• .oz.au – Historical domain name for Australian sites. Australia's original top-level domain for use in the store-and-forward Internet messaging system MHSnet was .oz. The top-level domain later officially became .au and those domains in .oz were moved to .oz.au. As of April 2011, many subdomains under cs.mu.oz.au and ee.mu.oz.au are still in use within the CSSE and EEE departments of the University of Melbourne.
• .telememo.au – A mapping domain for X.400 addresses. Has since been deleted

Other Australian domain names

.au is not the only top-level domain name assigned to Australia. Some Australian territories have their own ISO 3166-1 alpha-2 code, and therefore have their own ccTLD as well:

• .cx – Christmas Island
• .cc – Cocos (Keeling) Islands
• .nf – Norfolk Island
• .hm – Heard and McDonald Islands

They are also two geographic top-level domain names assigned to Australia in which are used by individuals and businesses within a particular region, they are:

• .melbourne – for Victorian registered businesses, entities associated with the state of Victoria or Australian citizens and residents with a Victorian address.
• .sydney – for New South Wales registered businesses, entities associated with the state of New South Wales or Australian citizens and residents with a New South Wales address.

As the appropriate authorities were late in recognising the need to manage these, most were registered by entrepreneurs for use as vanity domains unrelated to the locale they serve. .cc, for example, is now operated by VeriSign. .hm represents a nature preserve with no human inhabitants.
