If we can get back onto topic about the aviation aspect here...
Due to the delays, that 747 isn't going to get out of Learmonth into Sydney before curfew (maybe they could have a dispensation if it was full of evacuees, but not as a reposition). So it leaves the question what will happen with the QF crew who have to overnight now in Learmonth? My point being these staff were just transporting possibly infected evacuees, how would a local hotel feel about having them? Or will they get put up in the RAAF quarters?
