"What would be the cost had a Falcon 7X been chartered?"
A civil operated 7X goes for between US$7-8K per hour and there is about 50 hours flying in the route you've mentioned so US$400k so far not including enroute and landing charges, handling, catering, crew accommodation & costs, ground transport, admin and planning etc etc etc so add in another $100-150k per month for a 3 person crew. Lets call it US$500..... so somewhere shy of AU$700k so far for the plane alone.
