Harrys would be a good starting spot. They have just added the Tiwi Pearl (new sunken ship) to the area at Harrys. A search on the internet or through this site should give co ordinates for this. It's no big secret.
Just look for the crowd and sound around
Snapper have moved into the bay and are becoming more commonly sought. If bottom bashing then I would suggest Pillies or a squid bait unless you know how to handle a soft plastic.
