By the comments posted thus far, it's obvious no one knows how much traffic goes through this area.
Like how much? All the traffic in Australia? We have traffic here? Serious? Some of you blokes need a trip to a busy country. Australia has no traffic and a declining aviation industry.
On one breath you blokes tell me Australia's aviation industry is in decline, then on the next breath you tell me we should shut down an aviation business that is successful just because they operate where a few other aircraft fly. Drop zones are tiny and easy to avoid. Whats wrong with you guys?
