What has been left out is the fact that you simply have to add a procedure, which is common in all other leading aviation countries in the world. That is an aircraft on an IFR flight plan reports when visual. We already do this in controlled airspace. We have no such requirement in uncontrolled airspace, even it is radar covered because this used to be manned by a flight service officer who was not allowed to use the radar.
Look at the Benalla situation. The alarm is enabled until the pilot reports visual, at that point the alarm is disabled. It is one click of the mouse or keyboard depending on the system. We have the LSA/MSA alarms enabled at terminal airspace like Cairns, why not also use it in other airspace where we have good radar coverage to below the LSA and mountains in the area. Proserpine is a good example. To have this system at Proserpine would require no more staff, one extra call i.e. kilo tango kilo is now visual. It could prevent 100 people losing their lives.
