There is no way that the airlines bringing people back home - those being almost entirely foreign airlines (because Aussie ones (and there's really only one) will not do it because there is no money in it) - will fly directly to a remote point in the GAFA with a minuscule capped pax load if there is nothing there for them to take out again ie full pax load or freight. That's all that's keeping them doing it out the capital cities now.
Great opportunity for Australian airlines with knowledge and experience of remote aerodrome operations to fill the gap
Which Australian airlines who also have the ability to operate long haul international would they be? As I said, we now only have one airline capable of international operations. The idea that the Aus Govt will charter innumerable QF flights (at great QF demanded expense) to cherrypicked destinations overseas at the frequency the foreign carriers are currently flying is ludicrous.
