How the number is built
$60.00 base, plus $3.30 per kilometre, plus the $1.32 NSW Passenger Service Levy. Tolls, GST and airport fees are inside that figure rather than added to it.
The formula is the ceiling, not the floor. Published corridor fares sit at or below what it produces — on the long South Coast and Western NSW runs, noticeably below, because a 250-kilometre drive priced strictly per kilometre would be a number nobody would pay and we would rather publish one they will.
The receipt for any route shows both figures and the gap between them. That gap is not a discount that expires; it is what the corridor costs.
