Yes they did. Under aviation rules, Rex planes were under the size that required screening. No issue there. But Qantas, who compete with Rex at Dubbo, saw a shrewd opportunity. So Qantas announced with much fanfare that they would introduce an occasional flight in to Dubbo of a larger aircraft of the size that legally required screening. This forced the Dubbo Council to introduce screening for all aircraft, including the Rex planes that did NOT legally require screening. Rex understandably objected to this imposition and took the Council to Court. They lost the case, but the idea that your competitor can force up your costs by taking unilateral action, left a nasty taste. It opened a Pandoras box.
