In my opinion the Redcliffe peninsula offers some of the best foiling locations in the Brisbane area. It offers deep water with parking only metres away so no long walks.
Almost any wind direction can be foiled, but primarily NE and SE in summer. Tide doesn't effect the beach's shown though super high makes kite launch sometimes difficult but no problem for wings. The three beaches I have listed are sand, with a grass set up area. Yes, there are rocky outcrops around, but any of the locals will give you an idea of where they are and only really an issue on a lower tide. We have a great crew up here, wings now sometimes out number kites in stronger winds. The BOM station at the end of Redcliffe jetty over reads by about 4 knots, so winging is good when readings are above 19 knots,

A isQueens North, this is where most of us foil, good parking and toilets. Protected at the southern end in a SE on a mid to lower tide.
B is Queens South, parking isn't as good but protected at the northern end in a NE. Just not too far north due to rocks, stay south of the apartment block.
C is Bells Beach, good for SW in winter.
When the wind is up we get quite a nice rolling swell, bigger when the wind is from the south. Think up to 4 ft faces to play with while foiling downwind. I've done downwinders from Shorncliffe Jetty to Queens on a good SE, or the other way in a NE though not as good as the swell is smaller.
