On Track,
Yes. Flight Safety Australia mag published some plots of VCAs
(PDF article). Lots around that 700ft step and a few around the coast in V1. Those tracking coastal west of V1 without a clearance are especially noticed when rwy 25 is being used for arrivals... in which case we get a breakdown of separation incident with aircraft on final approach. Same goes for the 700ft step vv 16L/R. You may see traffic spotters over that area who have a clearance, however.
Wheeler,
I can see the need for MBZ procedures in V1 moreso than the LOE by the nature of the traffic, ie, nose-to-nose at same altitude. On the IFR RAS point, SY Radar doesn't always get a chance to pass VFR traffic... it's all workload permitting.
