What about the concept of providing some infrastructure and jobs by putting towers and controllers back at some of our major regional airports rather than relying on ADSB to do the job.
In my view, the greatest threat of an accident in Australia involving RPT is not during the cruise phase, it is to going to be a mid air collision of a high capacity RPT aircraft operating at regional airports mixing it with GA while trying to operate on two radios - this is where close in control is needed.
Jeez, you can go to just about any country airport in India and they have an ATC tower, fire service and flight briefing....at every airport.
First world country - sure we are.
Infrastructure & jobs required.
