Archerfield means $$$
I remember around years ago ago, a C152 dual at archerfield was going for $220 including GST. Taxi time and to RWY 10s was approx more than 10 mins including runups if your lucky. The time to reach the training areas added another 7-10 mins. Actual instructional time in a 1 hour flight to the training area was about 20 mins. That is a lot of money wasted on taxi time, ldg fees and transiting to training area. I still think training at non controlled aerodromes like Redcliffe and Cab can save you $$$$.
