I will answer this the best I can.

It is my personal opinion and in no way representative of Airservices that ADSB mandate was introduced unnecessarily early. I would have waited until about 2022. However that is only my opinion. Others will certainly disagree.

I did no such thing. I pointed you to a piece of information that is in the public domain that I thought answered the question being asked. You can draw whatever conclusions you wish from that information. However I think saying it wasn’t expected to provide any safety benefit would be twisting the facts. The benefit is certainly limited compared to at higher levels.

I don’t think ADSB is the solution to this. The only form of ATC I can think of that would work in the circuit area is tower. You don’t want radar standards applied in the circuit at anything other than the busiest aerodromes. Circuit areas are too dynamic and the scale doesn’t work at the enroute level. When you are responsible for 400SQM of airspace with dozens of aerodromes you can’t watch every circuit area. Some form of ADSB in may be useful here, but I suspect in non controlled aerodromes lookout and listen out will be the best we have for quite a while. Outside the circuit area and in what you could probably call the terminal area I think there are viable solutions that could definitely help.

CASA and Airservices as a whole? No, that would be totally unjustified. Certain elements within each organisation? Well this forum isn’t anonymous so I will let you all draw your own conclusion.
As for ADSB, calling it useless is unjustified. Like any technology, it has limitations. The people relying on it have to know the limitations to know what it can and can’t do. The more appropriate question would be did the benefit justify the cost. When ADSB mandate first happened and ADSB cost $40k or more to fit? My answer would be no. In the next few years as the install cost falls, the technology and system improves, and coverage gets better, absolutely I think ADSB is appropriate.
The answer to your final question that you weren’t going to ask but then half a sentence later asked would be I don’t know any better than you do.
