I'm not sure how ADSB would make a big difference to the current situation...
Quite alot actually. Radar separation standards are NOWHERE near as prohibitive as Procedural/Non-Radar standards. So in effect you could have 3 times the volume of traffic on a designated route AT THE SAME LEVEL within @ 30 miles of each other, than we currently have. Feeder fix management can be coordinated from departure 800nm from Perth and sequenced much more efficiently.
Requests in Flight Level change could be instantaneous as opposed to waiting for what seems like ages; crossing a/c could be instantaneously separated without the need to coordinate through next sector etc etc. Need I go on.
It would make an enormous difference.
