Hi, I spent a week down in QN learning some mountain flying skills about 2 years ago as a PPL, before starting my CPL training. I had an absolutely fantastic time - learnt HEAPS, and the scenery was spectacular. Yep, the pricing is a little on the high side, but you get what you pay for I reckon. The people down there are all friendly and welcoming and the instructors I flew with had been trained by Carlton Campbell.
The only regret I have is that I wasn't down there longer. If I didn't have other committments I would have seriously considered doing my CPL down there.
