Because the charter companies engaged by the govt and insurance companies to contract such services are driven by the lowest common denominator: price.
The parameters for the tendering of medical transport services

Good point indeed. Would that include a two-bit hack outfit in FNQ with prehistoric Dash 8's that does medical evac wotk to places like PNG while not having said permission granted to them on their AOC?
