It depends on what you like and your skill level.
Brighton is good but gets busy, We usually go to scarbrough north of the harbour on a Nthly to N/Wly and usually have the place to ourselves.
Bribie is good on the surf side on a Nthly to a S/Ely but gets a bit bumpy. Bribie is also good on a S/W at the start of the passsage.
Caloundra has heaps of spots and good surf, however is 20 mins further than Beachmere from Mt Mee and gets very busy on the weekends.
You should get the telescope out and sit at the Mt Mee lookout and see where all the kites are flying.
