I am currently not taking new registrations for this domain. Existing domain holders are unaffected, and should email any required changes directly to hostmaster@dropbear.id.au.
dropbear.id.au offers fee domains to Australian citizens. You can read more about its history on the Policy page. Now that .id.au has been opened up for general access, I'm sure most people will be paying one of the commercial registrars for domain in the .id.au namespace, rather than the longer and more awkward dropbear.id.au namespace.
You will need to create an AUNIC handle if you havn't already got one.
If you need to update your personal details, you can edit details stored in your AUNIC Handle.
