Is your "SFC to 5000ft agl or CTA LL" whichever is the higher, or whichever is the lower? Given that you say that "[o]verflying aircraft should monitor (Insert name of new MBZ thing) frequency while overflying lateral limits but above 5000 agl for conflicts", it seems you're advocating the lower. Otherwise the overflying aircraft would, by definition, be in CTA.
If yes, you're advocating for the upper level of the Ballina BA/MBZ/MBA to be lowered to 5,000' AGL rather than remain at the 8,500' AMSL C LL / 6,500' AMSL C LL. Is that correct? It does make a difference to whether an aircraft overflying at e.g. 5,500' is obliged to make an entering call at the boundary.
And you're advocating for the Lismore, Casino and Evans Head CTAF to be changed to something other than 124.2. Correct?
The Port Hedland BA is 20 nm radius of the ARP up to 8,000' AMSL. Are you advocating for that to be reduced to 15 nm radius and 5,000' AGL? Given the kinds of traffic in the Ballina BA, there'd be no objective justification for the BA/MBA/MBZ dimensions to be larger at Port Hedland, would there?
