It's all very mysterious. Fly IFR in the USA and the ATC frequencies are going like machine guns with hardly a space to get a word in for a clearance request.
Fly in the similar airspace in Australia and you can go for so long without ATC saying anything that you call them to see if you are still on the air. Often they answer " it's a bit quite today" .
It would appear that with a bit of airspace re organisation we may actually be able to provide a class E service at Ballina at no extra cost.
