At lunch time Coffs becomes a CTAF and before and after day hours, the fact that when the controller is not there you are allowed to transit as a CTAF, the reasoning is a little bizarre, you would think it would be safer with a controller. There is no heavy traffic through Coffs and no reason why all aircraft could transit. I owned a hangar at Coffs for many years and transit a bit these days (with PPL in LSA plane ), and they like you not above 1000' and over water, it is a very easy procedure at Coffs as all landmarks are well defined and radio is minimal, it would be very easy to be trained to use coffs airspace to transit. The controller mostly keeps RPT over land and light aircraft over water also gives inbound light aircraft runway 10 to keep them off the big runway. I can not see any reason to let all aircraft transit Coffs and with increased safety as the West side of Coffs is not good terrain and usually cloud covered.
Port Macquarie is just as busy as Coffs and I believe it is busier, it is not control and has easy access around, I would like Airservices to explain that and Casa might try explain the safety issues in forcing people west of Coffs through Less than ideal conditions.
There is no will by Airservices or Casa and no way they want to listen, they want everyone to do what they say and blame safety issues on those not doing as told. Anyone who transit Coffs Coastal is taking the safer option. SURELY safety is important.
