Digression. Nothing to do with Jetgo
You answered your question in your second paragraph. No one said it can't be done.
I've spent many years flying VFR and IFR in the outback so am pretty familiar with the real world, if that's what you want call it.
Give me one good reason why you wouldn't fly a turboprop or jet IFR on commercial/awk ops in outback Oz? Even on short positioning flights from the mine to say Isa or Laverton.
