Requirements
Who can register a .com.au?
- .com.au is intended for organisations and businesses only. You cannot register this extension as an individual.
- You may register if you are a company, registered business, sole trader or partnership, or the owner or applicant of a trade mark registered in Australia.
- The domain name must exactly match your name, business name or trade mark, or be an abbreviation or acronym of it. It may also be closely connected to you or your activities in some other way.
- An Australian address is not required. Australian citizens living abroad are also eligible.
- The registrant type, the identification number and the name provided must match. This is checked.
Additional details for registration
- You provide the name of your organisation. If you register on the basis of a trade mark, you provide the trade mark name exactly as it appears in the IP Australia trade mark database.
- You state the grounds on which you are eligible to register, for example as a company, sole trader, partnership, registered business, trade mark owner or trade mark applicant.
- You provide an identification number, such as an ABN or ACN, a trade mark number or a registration number from an Australian state or territory.
- An ABN or ACN is checked against the Australian Business Register (ABR), and a trade mark number against the trade mark database. You can check your details yourself beforehand at abr.business.gov.au.
- You state why you are entitled to the name: it exactly matches your name or trade mark or is an abbreviation of it, or it is closely connected to you.
- If your organisation has a registered business name or a trade mark that matches the domain name, you can also provide that name along with its number.
- If you provide an Australian address, you must include a valid state or territory, such as VIC, NSW, QLD or WA.
Good to know when registering
- When you register, your identification number and the name of your organisation are checked automatically. If these details are incorrect, the registration cannot go ahead.
Transfer
Transferring a .com.au
- First request the transfer code from your current registrar and pass it on to the new registrar.
- The transfer requires a signed request from the registrant.
- You must confirm the transfer by email. Only then will it be carried out.
- Start the transfer in good time, not just before the domain name expires.
The transfer code
- You always need a transfer code to transfer a domain.
- The registrant or the administrative contact of the domain name can request the code from the current registrar.
- Check that the code is correct before you start the transfer. With an incorrect code, the transfer will fail.
Owner
Change of registrant
Change of registrant
- Both the current and the new registrant must approve the transfer by email. If they don't, the request lapses.
- The new registrant's details, such as the identification number and organisation name, are checked again during the transfer.
- Any full years remaining on the domain name's term pass to the new registrant. A remaining term of 1 year and 11 months counts as 1 full year.
- Minor corrections to the registrant details can be made without a change of registrant. If you want to change the name of the registrant or the organisation, a full change of registrant is required.
Renewal, cancellation and quarantine
- You can renew a domain name no earlier than 90 calendar days before its expiry date. Renewing earlier is not possible.
- More details can be found in the registry's renewal, expiry and deletion policy.
