Hey Bogan,
yeah I have kited it a fair bit in the last 18mo, I'm a marine biologist and go up there for work 4-5 times a year. That's me riding in the gallery pic.
Great spot...very strong and consistent SE wind from April to Sept (we are talking averages of 30 knots for weeks, even months on end), beautiful blue lagoon to kite in. The island itself and the surrounding reefs are amazing - one place you should put on your "see it before I die " list.
Expensive to get there (about $400 return ex Cairns currently - book through Voyages 1300 134044 ) BUT, what a lot of people don't know, is that there is a nat parks camping ground there, within walking distance of a great kite beach, so you can stay there very cheaply once you are actually on the ground. You have to cart all your own food and camping gear so you have to travel light or pay some excess, but there is also a fortnightly barge that services the resort so you might be able to get some gear on there.
Let me know if you want any more info. The director of the research station (Dr Lyle Vail) is a keen kiter, as is his son Alex (when he is there on uni holidays), and from time to time some of the transient resort staff have kites with them too, so there are a few kites flying from time to time.
I'm heading up on monday for 3 weeks, got the 8m and 11m packed!

Also going to be there in July, August, and October. If you are there in those times, pop in to the station and say g'day, we can organise a sesh.
