The nature of the corridor
Europe to Australia cannot be flown non-stop by the aircraft used for patient transfer. Every dedicated repatriation on this corridor is a staged operation: multiple sectors, technical stops, and either crew rotation or planned rest, all while maintaining the patient's care.
That makes commercial options unusually attractive here. A stable patient travelling seated with a medical escort, or on a commercial stretcher where an airline approves it, avoids days of staged flying and a very large cost difference.
