There you go ...
YOUR PLAN .... OK then
.
.... so you want to exploit ATC further by having them provide E at places like Benalla ..... hmmm ..... and yet your reason for closing the tower at Proserpine (and the like) was?????
.
You and your side kick refuse to take into account that the US are not running E, it is in reality hybrid D where surveillance exists .... FACT!
.
Go and ask the ATC's in the US how they actually operate their airspace (real life traffic services) and apply that to the nearest ICAO classification
.... and that will include the VHF and TXPDR requirements within distances of location X,Y or z as per the AIM and related!
.
Unless and until you do that .....
