Hello Clint,
Brisbane has some good spots if you cannot be bothered to drive an hour to the closest areas open to the ocean. It has some flat water and some spots with wind chop. Size of the wind chop is directly proportional to the wind strength. Try the Sandgate area or Redcliffe. If you have the means and time to drive an hour or so both north or south bound you can get to some awesome open ocean waves. I can really only comment on the Sunshine Coast but try Caloundra and Maroochydore (Cotton Tree) in an out going tide only or any open stretches for down winder action.
Good luck bro
