Fuji. You would do it bit by bit.
Allocating E to low level at Ballina would be a start. Would be very similar for the pilot to operating out of Coffs when IMC exists.
Educating VFR pilots to operate without unique Australian frequency boundaries on charts would be simple. It worked for 3 months without incident.
Just monitor the ctaf if in approach and departure airspace otherwise relax and look out!
