I haven't fished this time of year but i normally make at least one trip every year. Berley up at almost any point in the harbor and some good size snapper can be pulled aboard. Have also heard of great fish being pulled from just inside the harbor mouth all year round. On the attached map i have marked some spots that have proven themselves for me. Good luck out there mate be sure to let us know how you get on.
