Apart from between 5000ft-10,000ft, a combination of those are already a requirement for VFR into a CTAF or operations in G: mandatory transponders for all aircraft above 10k, mandatory carriage and use of radio for all aircraft above 5k, mandatory carriage and use of radio in a CTAF. Mandatory transponders for all aircraft in a CTAF for be a safety improvement: why though does the airspace class have to change though (with it's increase in cost, complexity and inconvenience)?
What would be the use of introducing mandatory ADSB for all IFR aircraft if non pressurized aircraft spend 90% of their time in uncontrolled airspace and still only get a 1930s style traffic information service?
What, a RIS is 1930's style? Open your eyes!!
If procedural approaches in Tasmania - with its lousy weather and big hills -are as safe as survailance covered approaches it means you don't need survailance anywhere . And that's clearly not so.
For goodness sake Dick, this is the 2015s, with great FMS nav systems and EGPWS. You don't base a complete airspace system on stopping aeroplanes running into hills! ATC's purpose is to keep aeroplanes apart. Do the traffic levels in Tas require radar-like approach services? Probably not!
