We were told in Aus that we needed to mandate ADSB years ahead and more prescriptive than the US because they had more low level radar coverage.
However we don’t use the ADSB for lower level class E separation services.
Above FL300 there has always been no measurable risk of collision especially after TCAS was mandated.
Huge misallocation of resources that has contributed to the demise of GA in Australia.
Sounds as as if the suppliers of ground stations are ripping off the industry.
