This is a big development. From March 24, you will be able to obtain a .au domain.
.au direct registrations will be available for general use by any person or organisation, provided they have an Australian presence.
If you currently hold a domain name in any other .au namespace (eg. com.au, id.au etc.), you’ll be able to apply for Priority Status to register its exact match in .au direct during the six-month period from launch.
