I actually think this latest proposal,solves most problems.
ATC won’t be upset, the aircraft flying in or out of the unmarked airstrip will be able to communicate with the ground or another aircraft in the circuit (within 3 NM and below 1500AGL), the transmissions won’t be heard very far away because of the low height so less interference between the many locations using 126,7. That’s pretty good!
All that they need to do now is allocate discrete frequencies other than 126,6 for the many marked busy airstrips currently using it such as Yarrawonga and Renmark.
