Most domains – such as .com, .net or .biz, – are available for anyone to register. However, some domain names come with extra requirements you will need to meet. Domains can be 2 to 63 letters, and words can be separated by hyphens, but not spaces.
.nz
These domains are intended for people in, or with ties to, New Zealand. Anyone can register them – there are no restrictions.
.com, .net, .biz, .info, .org
These domain names are not restricted or regulated by .au Policy Rules. They are therefore policy free and anyone can register them. If you own a company name, or a trademark, register an .au.com domain name to prevent anyone else registering that name.
.com.au, .net.au
To own a .com.au or .net.au you must be an Australian registered company, or business with a registered business number (ABN, BRN, BN).
(The licence requirements for a .com.au and .net.au domain name require your business to be registered for business in Australia, this means registering your business or company name with one of the official Government Authorities, eg ASIC, State Dept. of Fair Trading, or alternatively by obtaining an Australian Business Number (ABN) from the ATO.
The domain name you order should have either be an exact match, acronym or abbreviation of the supplied business registration, or it should bear a close and substantial connection to the domain name.
.org.au, .asn.au
To qualify for these domains your organisation must be a “non-commercial organisation”. The domain name you register should have a solid relationship to the organisation to which it represents.
asia, .eu, .ca, .es
You need to have a presence in particular countries and/or comply with local registration requirements.
.id.au
Especially designed for individuals who reside in Australia. You may register ANY personal name by which you are known.
