I agree entirely with the strategic point that not much done about aviation in Australia is based on proper risk and cost/benefit analyses. As I've said many times before, most of the decisions about aviation regulation in Australia appear to be about politics, thinly veiled as safety.
So, what would we anticipate an objective risk and cost/benefit analysis of the ADF's airspace requirements in Australia to produce, and why?
If all that ADF-related Romeo airspace that's vastly larger compared with other Western countries with more aircraft and grumpier terrain is justifiable on a risk and cost/benefit basis, let's see the analyses. Us nobodies will do our best to understand them.
