Just a shameless plug for Kite Boarding Cairns. They are right behind the end car park at Yorkys Knob, Cairns QLD. I took my 10mtr out at Yorkys for the first time on my recent trip and POP the bladder gave up the ghost. Took it straight to KBC for their opinion and $50 bucks later it was properly patched and working, and has been fine ever since. I later learnt that I was packing the kite wrongly and this caused twists near the tips of the kite. Now I pack it properly and no problemo. They also gave me great tips on where to kite and what conditions to look out for. Very friendly and highly recommended.
