Mike,
While you may be correct about the frequencies you have listed,
ACA manage the allocations
We at work hold the licence for a number of frequencies,
two for communications, the others for radio maker buoys,
4 for SDBs and 4 for our droppable life rafts.

Subject: Re: [Aus-soaring] Paper Overload
My recollection is that the entire aeronautical VHF band is covered by a
"class licence" and that certain frequencies have been allocated for
specific 'community' purposes - in particular 119.1 is for aero clubs,
119.2 is parachuting, 122.5 ,7 & 9 are gliding, 120.85 is for sport
aviation air-to-ground, 126.35 is for aircraft-to aircraft comms below
FL200 and 128.95 above FL200, and 123.45 is now officially a GA
aircraft-to-aircraft one.
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.
