It does seem that General Aviation in Australia is a minority, and most of the general populous look at it with either disinterest or anger. It's a shame the average person only see's aircraft movements around Archerfield as bothersome noise pollution.
With the majority not giving a damn about the shape of aviation in Oz, it's more than likely aerodromes will have to keep closing or moving out of the towns that have grown up around them.
Archer should stay for now in some capacity, but the day WILL come where they close it for good.
