Defensive or denial?
There's not many places I have seen that need to prioritise multiple Maydays and Pans and also sort the normal daily civilian traffic with forty or fifty min fuel, fast-jet and heavy jet multi-national military returning, (Townville sometimes too). Perhaps there are civilian locations that are similar and maybe this is your special place Coral; no doubt you are very good at controlling such traffic complexities. See you in sandy places one day perhaps.
I know of a few Australian civilian locations that do have some rather special challenges but they are not the high profile sausage factories with impressive levels of human capability. West radar, Janders, Bankstown and Tops come to mind and then Albury or Cairns on a good day; no doubt others I haven't seen or worked. There's certainly a component of tactical control at these places.
Prior to the muddy bits, my original point was that there are reasons why radar is not being used by AsA in the Northern Territory.
