On launch day - 24th March, all names that match an existing 3rd level domain will be put into Priority Hold until 20th Sept 2022, and can only be claimed by eligible holders.
Any name that does not have a matching 3rd level domain can be registered on a first-come first-served basis from 8 AM AEDT on Oct 04, 2022 onwards. This means that auDA will process the first completed .au domain registration application that it receives.
