you should check out pebble beach at sandstone point when there is a high tide.
it's probably one of the best learner spots around and is very close to you. in a south easter it is dead onshore. it's fairly shallow and the water is flat.
for learning to plane, planing gybes etc it's one of the best spots i know.
turn left into oxley place off bestmann road east, drive down the hill to the carpark.
rigging is shaded by trees.
the downside is you will most likely be alone when sailing there but it is a sweet spot.
this is a mid tide.
just found this previous post.
www.seabreeze.com.au/forums/Windsurfing/Queensland/Another-beginners-spot/p.s. reef is at the very western end where the mangroves are.
shell fish are at the very eastern end out from the mangroves.
i have so many good memories of this place. once you are sailing short boards it is an exceptional speed sailing area or if you sail upwind a kilometer or so there is a bank you can wave sail.
if you want to get a feel for the layout of the bottom, visit it at low tide and the entire area will be exposed so you can see where everything is.
