I spoke with DIT some time ago about others module they are working on- their SMS and SSL modules were planned to be out last year. They are great blokes , but I wouldnt hold my breath on the timing of the module
Alos in response to tim's post above , AU domains can't contain special characters except a hypen.
4.3 Registrars must check that the requested domain name:
a) is from 2 to 63 characters long;
b) contains only letters (a-z), numbers (0-9) or hyphens (-), or a combination of these;
c) starts and ends with a letter or a number, not a hyphen; and
d) does not contain hyphens in the third and fourth position (eg. ab--cd.com.au).
4.4 In addition, registrars must check that the requested domain name is not on auDA's Reserved List. The Reserved List is available on auDA's website at http://www.auda.org.au/policy.
