Here is a concept (in simple context). All the respective regional councils form a cooperative enterprise regional airline/s.To secure services to regional centres. To secure employment for local aircrew & support services. Attract other parts of the airline operation to regional Australia. The structure would take some effort to establish however, with today's technology ongoing management should be wholly feasible and no more costly when you consider revenue streams and current subsidy arrangements . PM, PM me for an elaboration to the concept. You're welcome!
