The vision thing:
Where are the float plane services linking every inlet, lake, river and reservoir to the capital cities? Even Vietnam has something like that.
Where are the turbine helicopter businesses in every town ferrying tourists, hunters and hikers to and from the wilderness?
Where are the grass strips in parks with bush camping facilities?
Where are the airport cafes and restaurants doing a thriving fly in / fly out business?
Where are all the LAMES schools and aircraft hire services at every regional town?
Where are the aircraft friendly towns, communities and estates?
Where are all the regional charter operators running scenic flights as well as delivering tourists to outback destinations?.
Where is the economic growth, investment and jobs such an industry could provide?
Stuck up the anus that is Canberra.
