We have never had a terminal radar service in Tassie so we never need to"
Forget that the most common form of fatal accident by airline pilots is a controlled flight into terrain and the best way of preventing such accidents as per the NTSB is to use ATC with radar.!

They would probably install a combined Thales STAR2000 + RSM970S, giving around 250 mn of secondary radar, and 60-90 mn of primary radar.
Yep, can just see Emirates and all the other International airlines agreeing to that one. You only have to look at their submissions to the current debate about the Long Term Pricing Regime and network costs.
I'm sure the boys and girls in LT & HB would love the extra surveillance capability of primary radar but at what cost? And what other projects would have to be delayed or cancelled to provide sufficient project resources, technical staff and $$$.

Presumably they did not put enough multilateration stations in or could it be that they located them in the wrong areas?
There is some truth to this, remembering that Tasmania has large areas of National Park and wilderness (I've seen all the glossy pictures in Australian Geographic) and so sometimes the locations might be a compromise, next best option. And with ADSB sites, more is better but once again $$. Contractors usually underestimate the number of sites required, often this is a "ploy" to gain contract variations, a bit like building a swimming pool and the contractor saying we needed extra steel, extra concrete, extra tiles, larger pump, higher pool fence.
