Don't forget Prof Fred Hilmer. Henry Bosch was the architect of user pays but Hilmer, with the support of the Libs, Labor (the illustrious Laurie Brereton) and the Nats, was the real instigator of corporatization and privatization.
The Government did very well out of the sale of the FAC airports $5b+ from memory and now the whole industry is fractured with GA dying.
As an aside, a beautiful day in south west WA today and 10 years ago plenty of lighties would've turned up for a visit and lunch in this quiet pretty coastal town. No landing fees. Today, one arrival only - a gyrocopter! Says it all really, the heart of GA has been ripped out by an incompetent regulator, greedy airport owners operating under the protection of the Airports Act and politicians who are so out of touch it's disgraceful. Can't see a solution, regrettably.
