There is still the exemption process until that happens.
I seem to recall from an earlier thread that Dick was denied an exemption by CASA (for I think a flight to Western Queensland?) and was looking to a Court challenge.
I suspect the primary issue here is that Australia has imposed an ADSB requirement ahead of most of the rest of the world, before all manufacturers have developed compliant Service Bulletins for ADSB installations in existing aircraft? I don't think it is not a matter of cost, rather having available an approved installation method?
Exemptions are unavailable: one day a number of Australian corporate and private aircraft are safe to operate above FL290, but the next day they becomes a threat to airline safety?
Still not entering the debate. Only observations.
