Note that the Class licence covers only the radio transmitter in the aircraft, not a ground base station. These would need a licence from ACA.
Frequency allocations within the aeronautical band are managed by Airservices, who provided the six 'new' frequencies around the time of the last Nationals to be held at Benalla in the late 90s (i.e. later than the Worlds there), but they were for a temporary 1-year period and so have since officially lapsed, though I am not aware of them being reallocated to anyone else. As RH noted, Airservices has just released a notice of proposed rule making to start allocating 25 MHz frequencies for ATC purposes next November, so if we want to keep those frequencies we have been using, we should approach Airservices asap to make the allocation permanent (and hopefully retrospective for the same six channels). It may be that they lapsed because of the few glider radios that were licensed in the days before the class licence was introduced, so nobody knows the number of people using them but everybody knows there were very few licensed sets in the past, when an aircraft radio had to be licensed.

Do the same for 122.7 and 122.9.
I've just ratted throught the ACA link and I think the answer to your puzzlement is that the listed licences are for base stations. I know my club at Central Coast pays to operate a licenced base station (122.7 and 122.9) and I'd guess all the other clubs with ground installations do too (bloody likely!). I notice that GCV and ASC both pay to operate a base station on all three gliding frequencies 122.5, 7 and 9.
I believe that aeronautical mobile stations don't need a licence to operate on any of the allocated aeronautical frequencies (118.05 to 136.95) but base stations do and the ACA list is a list of licenced ground stations.
122.5, 7 and 9 are "the GFA's" in the sense that a request to operate a ground base on those frequencies by a gliding club would be almost automatically accepted. There used to be a 'frequency allocation plan' on which 122.5, 7 and 9 were reserved for gliding operations but still required individual clubs to apply for a licence.
Cheers, Graeme.
(Go to http://www.aca.gov.au/pls/radcom/register_search.main_page and plug in '122.5 Mhz' as the starting and ending frequency and hit 'search')
Graham, methinks you know the back-story here. I'd sincerely love to know what is up on this front. Can you tell us what it is?
Yours in confusion,
Simon Hackett
