Dick,
Better still, ask who was responsible for the disgraceful changes to the original Airspace Act. If that hadn't been gutted, and all reference to risk management, defined risks, cost/benefit analysis, and the US NSA being the model for Australia to follow had not been removed, indeed all reference to objective standards (under Albo??) this nonsense (and much else) in matters airspace would not have been possible.
Indeed, if I remember correctly, a version of "promote and foster Australian aviation" was even in there somewhere.
Tootle pip!!
