generally they don't. If you are absolutely bloomenlootely desperate to sail at GC then seaworld carpark and the spit are about it, but neither compare to Wellington point in anything westerly. NW is great at Kirra in the surf, but not much good anywhere else on GC. See the light like most other GC folk and simply head to Wellington point and save yourself the grief when westerlies are forecast. Victoria point is good for sw to se, wello is good for sw to nw. To get to wello take the beenleigh redland bay exit and then turn left into mt cotton road.
