I was new to Brissy a while back too and used to travel to gold coast or caloundra (nice but sooo far) but now I go to Manly (OK in SE but not so good in S) its a great spot in my opinion, is close, has grass rigging area, some flat water + bumpy stuff too, not really tide affected, good launch site ohh and lots of mud at low tide. Best way is to try them all and see what you prefer.

Dead south, Vicky point.
SSE Manly
SE Wello

Thats where I reckon they work best with the swell direction and surrounding land.

And then there is redcliffe...

Ann St at caloundra is good if you want waves.

A place called Beachmere near bribie island - armpit of a town - no one ever there - goes off in a south-southeaster.

It is set up to give you ramp after ramp on the way out and backside swell riding if its windy - its been know to get to 4-5ft on windy SE's.
