Hey Goldy68,
I feel your pain.
From north to south:
Redcliffe - rolling swell
Wellington Pt - Big bay but you've got to be careful at low tide
Victoria Pt - Good speed strip at low tide, Haircut posted a good video showing the choppy conditions when the tide's up a bit.
Shearwater - Catches the southerly the best out of most spots on the gold coast. Awesome in a runout tide. If wind is marginal and tide is coming in then don't bother, you'll end up doing the big walk.
The train - Good speed strip, but if it's any further south than SE then forget it (gusty). Good when the tide's wrong at shearwater.
Miami (waves) - Wind must be SE or more East. Waves aren't too gnarly.
Currumbin Alley (waves, with flatter water inside) - Wind must be SE, and 20-25 knots measured at the airport before I'll go out. Too flukey otherwise.
Tweed Golf course - Short run, but good if you don't want to drive to Southport. I was out there today (with too big a sail

Kingscliff (waves) - Checked it out but haven't sailed there yet. Waves look quite nasty, not sure I've got the cajones to take it on just yet.
Flat rock, Ballina (waves) - This is a legendary spot for windsurfing, I haven't sailed it but on the right day apparently it fires up.
Those are the spots I've sailed at (except for Kingscliff and Flat rock), there are rumours of others. If you're keen to meet up then I'd like to check out some new spots south of the border for a change, most of the crew on this forum sail from Southport north.
