ya good for kiting in waves, in a NE you can go downwind to maroochy river mouth for flat water, no crowds but plenty in the river

I was at Twin Waters a couple weeks ago and as mentioned Cotton Tree was great on a NE with an outgoing tide (Luckily the sun was also out so the GF happily sat on the beach all afternoon with minimal nagging). We drove round to Cotton Tree however I saw a couple guys did turn up from a down winder that went past the beach out from Twin Waters.

If you've got a significant other to pick you up and a NE'er then you're best walking out to the beach, launching there and heading down to the river mouth.
