cheers for the tips bondalucci. sounds great.

mooloolaba is one of my favourite spots. early august is probably a little early for the season but you have a good chance of picking up a NW wind which is a good direction.
it's a great spot for ocean slalom sailing and wave jumping with waves coming in and cross/on conditions. i am told by the locals there is a bank forming out from the river mouth but i haven't sailed it.
best bit about mooloolaba is the launch is not the usual close out sections you get at most beach breaks so it is user friendly.
