I'm not the expert that Dick asks for. But I was rather fascinated that for example, April 2015 the less than 7 Tonnes Movements were thus:
YSBK: 13376
YMMB: 20690
YPPF: 22152
Those South Australians must be doing something right with their flight training.
"Movements are the sum of Arrivals + Circuits multiplied by 2 ie (A+C) X 2"
