Frequently Asked Question
What are the registration requirements for registering a .AU domain?

In order to register a .com.au or net.au domain name, the applicant must:

- be an Australian registered company or have an Australian partnership or sole trader; or

- be the owner of an Australian Registered Trade Mark, the applicant of an Australian Trademark, or the owner of an international trademark including the Australian territory.

If you do not meet any of these requirements, you may apply for a trademark registration in Australia with our company here; please note that it is recommended that the trademark has the same name as the one used for your domain application. For instance, if the desired domain was “abcd.com.au”, then you would have to file for a word trademark “abcd”. After filing your trademark, we will be able to register your .com.au domain in approximately 3 weeks.

If you cannot wait for the trademark to be registered, we might be able to offer another solution. In this case please contact us via email to support@marcaria.com and provide us the name of the domain you wish to register and the purpose of the website.
