Go to a local School buddy!
Pretty sure QLD- the land of sun and surf would have quite a few schools

As for trainers you can get one on the buy & sell section for about $180 all the way to $350 for a 3 line, 3 metre foil. or $450 for a SLE/ Hybrid kite (The ones you pump up that most kiters use. The foils are self inflating like a parachute or a paraglider's wing.)
I would give you mine but I just bought it and whilst I have outgrown it, it's good for getting mates into the sport... Sorry.
