AVSEF, where are you?
Class E wouldn't be so bad if Airservices actually provided some approach controlling; it doesn't, of course (as we have seen at Coffs) and all this will mean will be ground and airborne delays waiting for the other IFR to clear the area, all the while fighting on the CTAF (eg Sunshine Coast A320).
The only good part of this is that VFR will require a transponder unless they are in the weeds. In fact, if it's deemed that IFR must have E to improve safety, then it's high time that ALL aircraft, regardless of airspace type, mixing it with RPT have a transponder for TCAS.
