Generally speaking it is safe, its just unfortunate that noise control at major airports takes priority over safety and common sense, and that at MBZ/CTAF(R)s we have big jets mixing it with bug smashers with no appropriate radar.
Radar will be implemented at these various locations after a media beat up with a near miss or actual mid-air. Its the only way it will occur, this was demonstrated in Launceston. The blatantly obvious accidents to be, are only acted upon as an after event.
I am not sure if its Dicks doing, but he certainly doesnt appear to be campaigning for radar implementation or possibly the next best thing ADS-B.
