I just visited the place, and from the video it looks like they showed the coastal route. I am pretty sure we went the inland route, but I figure you don't miss much. Next time it would be good to see the coastal route. If you are in Townsville, its not that far. You should go.
Unfortunately if you are expecting the tents on the beach shown in the video, you might miss out. Instead, they now have some pretty cool accommodation made up of giant water tanks turned into cabins. Its a great idea, and surprisingly comfortable. If you don't like wind blown sand outside, you are better off staying somewhere where there is no wind... i.e. Sydney. I don't mind wind-blown sand when its warm

I went up there because I am only starting out kiting, and in Sydney in winter there is no way I will get any practice. Its too cold, and its too gusty. Instead, I went to FNQ and it was warm and windy. Very windy. I am 95 to 100kgs, and for me I was trying to kite on a 6m one day and an 11m another day. I think I would have gone up there just for the weather. The Cape Flattery graph was showing 25 knots, gusting to around 30, and on the light day, 15 to 20.
It was interesting to see the comments on crocs in the post about the guy in Darwin, to compare this place to there. I went up to Cairns in about 2005 to try windsurfing up there. I was so worried about crocs in the water, even though there were heaps of people kiting in Yorkeys Knob, that I had to stop at a croc farm (in Townsville?) and see one for real. The guy there was pretty adamant that you just dont see them there in winter as its too cold and they prefer to stay in the rivers and sun themselves to keep warm. He was pretty certain that you generally don't see them in winter. It sounds strange, but I think the water is just too cold for them in winter.
Anyway, despite being paranoid about sharks in Sydney, I was perfectly comfortable body dragging in knee to waist deep water. I would have preferred if it was shoulder deep so that I could crash more. As it was I think the others were taking the piss out of me for body dragging so much, but hey, its easier than kiting

For anyone that is keen on getting out of a 13 degree Sydney winter, and going to somewhere more like 27 degrees, I would recommend it. Its a shame there is no windsurfing gear there though

With only 5 other kiters around, it would have been awesome.
I think the best thing about going there compared to Fiji in the past, was there was actually wind there!
