There is a Kiteboarding shop in Sydney called Kitepower, great service, great stock, friendly staff can't go wrong. If you are looking at a trainer I would suggest an Ozone Imp. I had one, got about 35 hours on it and that's what got me into kiteboarding. But ask the staff if unsure. Good luck.
P.S. here are the details.
