last week returning from Ballina, held at anna bay, at 500 ft, over ocean, for 45 mins, no probs getting through Coffs, but 45 mins at willy was frustrating especially when 12 is in use, getting through Nowra presented no problems either, and if your Not transponder equipped, they get you through in the most professional manner,
come to think of it, every time i have needed to transit wiliamtown, there has been a delay of at least 20 to 30 mins.
i know the lane to the west is there, but its not fun in a 15 to 20 kt noreaster, im not a fan of flying in rotor turb at 1000 or lower AGL
