The flight between Sydney and Ballina takes about one hour by an Airbus jet.
The Ballina Byron Gateway Airport is a small airport with I suppose 10 or so jet flights each day mostly to/from Sydney, Melbourne and Newcastle. There are no air bridges and passengers walk across the tarmac on arrival and departure as was the case with even major airports in my youth.
I took these two snaps walking across the tarmac earlier today when joining my flight for the return flight to Sydney.
The aeroplane is an Airbus A320 in the Jetstar fleet.
