happy valley in a n is doable but can be gusty, i have launched from golden beach and done the treck across bribie before...
yeah, mooloolabah is pretty good, winds not that reliable tho.
have a look today - northern nsw is already 20-25 at 8am...

i think the blackall range moderates the seabreezes and they often end up blowing 15-20 when the bay is 20-25 and nsw 25, that said i've had plenty of good n sails up here.
the bom forcasting 6 lows off seq this summer excites

me!
