'parkyn parade' is the spit road, (for N/NE) weekend parking can be difficult, when all those damn brisbane city slickers crowd the place!

You out can sail off the beach anywhere from Marcoola to Mudjimba in a NE no problems, lower tides easier, Mudjimaba does get coffee rock, but that's mainly an issue ,after the summer lows have eaten the sand away, this time of year it's not too bad. ( same goes for S/SE)
unlike cotton tree you don't have tides/currents to bugger things up and 4 million people in the water,
Just depends on how much time I have to which location I will sail, ( mudjimba is my local) and also wind strength...as the wind starts to go N/NW as the sun sets Mools works longer and it's pretty nice on sunset, plus great fish and chips for the way home!
and it at its best when the wind is +20knts as if it's marginal and the tide is on the rise, you will find yourself getting pushed onto the beach struggling to plane and hating it.
The wind and waves at Mool are pretty on shore, in lighter winds the swell is easy as and can be sailed with freerace or slalom gear no problems.
