No probs mate let me know when you are near Shoalwater/Safety Bay. There are other good sb similar to the Nugget I am sure. Need to have quite a bit of volume (my 5'2 has 29L), so chunky, wide, thick. Some use their surfboard but make sure it is not a skinny pointy big wave board as it will require a lot of wind. Which will slow down your learning.
I personally would not use straps unless you need to lift your board over waves, or jump or ride big waves. And of course once up and running and you prefer a more powered, fast ride through chop and waves. When learning straps may just hurt your ankles or knees as the board is moving around uncontrolled. You will be able to move your feet around freely hence position them intuitively in the perfect spot, and when falling off, it is a no pain exercise, strapless. Just try someone elses board, in flat water, point downwind. Bring the board close to your bum, bend your knees, just like with a tt. Hold the board by the edge, sine the kite, extend your front foot downwind. Again very similar to when you learned on a tt. If the water is only about ankle to knee deep you can as well point the board downwind, and just hop on it and hammer your kite. Takes a few attempts but with a chunky high volume board you will have just enough float to make it happen.
Also, as cauncy said, a smaller agile (wave) kite in higher wind may make it easier as oppose to working the crap out of a huge truck, which may respond delayed and by that time the board is under water or not pointing downwind anymore
Apply a bit more weight on the front foot i.e. don't edge as hard as on a tt as you will kill all the power. Keep the board much flatter on the water. Once up and running it goes upwind like crazy so don't worry about it too much.
Enjoy. Cheers, Andy
