There are multiple reasons for a domain registration to be cancelled. Some of the main reasons for this are:
- The registrant information you provided during registration is inaccurate
- You are not eligible for a .au domain licence
- You have used the domain for illegal, unlawful, or fraudulent activities as per the Australian law
- The domain registered to you was actually a reserved domain
- You have authorised the use of the domain to a non-related Australian corporate
- You have lost the domain as per a dispute resolution process
- The domain you have registered poses a security and integrity risk to the .au domain name space.
- The domain registration was cancelled as per a court order
- Cancelling the domain is in the public interest as determined by a suitable governing body
