Spent a couple of weeks up in Cairns, it was warm and very windy. Out at Green Island there were probably only 5 days or so out of 18 under 20 knots. About one week of that was solid 25-30+.
Green Island offers basically everything apart from hardcore wavesailing, there are conditions for speed, freestyle, cruising and bump and jump on high tide. The croc park and snorkelling is great when the wind is light.
Here is a video mostly shot on the island -
