The pilots that worked for Maslings, Hazeltons, Kendels, Davey, Norfolk Island and the many other "third level airlines" that built Australia serving the bush and Australia's protectorate, Papua New Guinea, occupy a unique place of honour in Australian aviation history.
Changing circumstances, increased aircraft operating costs, demise of the Rural Air Services Scheme (RASS) and other rural subsidies and changing CASA philosophies ensure there will probably never again be a viable third level airline industry in Australia.
