The government policies are ruining GA. The country will pay in a few years when there is no one to fly their main jet routes.
Privatisation of airports - costs quadrupled at Canberra the first year of privatisation and continued to increase since. Other capitals are similar

I know Deniliquin council took over the DLQ aiport and have shortened the runway rather than spend on maintenence - it no longer supports larger turboprops.... its probably just a sample of other rural airports.
Airservices - user pays - this cost is MASSIVE and was introduced about 10 years ago
Government does not recognise regional airlines are Australias infastructure. No support - no subsidies to service remote destinations (except QLD)

Airlines continue to take take take and do not give back in training ( one major airline in particular trains no one...)
