My Ma and Pa have a holiday place up in Hawks Nest. Great kite spot! I second everything that Nickoff said.
One of the best sessions i have ever had was out the front of the river mouth (just west of winda woppa). It was SE, 20kn. There were little waist high waves breaking on the sand bank. On the inside there was hundreds of meters of smooth flat water. There were small sand islands to jump and i was there with one other kiter.... and he left after 20mins. And it was warm. I'd love to score that again right now!
And... the bay side of of the beach right up near yackaba

. 25kn NE winds and water that smooth. Ohhhh drool.
Na Bennie it's sh1t. Don't bother. Leave it all for me.
Next summer i'd love to do the 30km downwinder from seal rocks to hawks nest.... or check out some of the islands (if i can organise a support boat).
