That is no reason to make it mandatory in Australia, and put one more nail in the coffin of what little is left of GA in Australia.
Made mandatory on the basis of recommendations made by those who will never bear the expense, based on no risk management demonstrated justification, much less cost/benefit justification, but "because we can". Or, now it is "reportedly ubiquitous".
After all, what is another $5,000-$10,000 when Safety Is Our First Priority.
Tootle pip!!
PS: Based on two recent alleged "loss of separation" incidents (an interesting concept in Class G, VFR/VMC) with at least one ADS-B IN equipped aircraft, I think we have seen a portent of the future, a mid-air in the circuit, because one of more pilots were looking at their ADS-B IN, instead of "looking out the window".
