Lucerne, NTL would only ever be a second airport, the main airport will always be SYD, but as a second airport NTL fits the bill nicely. The growth of Northern Sydney and the Central Coast plus Newcastle and the Hunter will see NTL do it by stealth anyway, and as for over farm land your still fairly high until nearly over Grahamstown dam, with Raymond Terrace still well to your starboard side. If you want flat terrain, and they do, then you have to expect it to be used for farming, whilst the farmers might not totally rejoice, the employment and a career for the young of the district will far outweigh, the cattle whinging. Anyway they are totally used to it, the fighters are noisy little bastards, much worse than commercial aircraft, and there are often three or four landing at once. The people of Willy and Medowie are very used to aircraft and would love a job close to home. In fact many are already airport workers.
