On 7 February 2008, ACMA announced that it would seek to implement contractual arrangements with the WIA for the provision of certain services, including the management of amateur examinations, the issue of certificates of proficiency and certain administrative functions, including the ongoing management of callsigns.

ACMA and the WIA are in the process of formalising the contractual arrangements. Subject to the outcome of these negotiations, it is expected that the WIA will be managing callsigns following the Ballot process on 24 October 2008.

At this stage, it is expected that callsigns (including two letter callsigns) will be treated by the WIA in the same way they were treated prior to October 2005 (that is, they will be available on a "first come, first served" basis).
