gday Dave. Try camping at the mouth of the Anan river (not sure of the spelling). Only bout 5-10min from cooktown. you can camp on the beach, lotsa areas. Can keep the boat tied to a tree (if you got a boat), if not, great fishing jsut at the mouth. last time i was up there, had some memerable fishing just at the mouth. Barra, queenies, more barra, HEAPS of Big tarpon, even had a whaler shark of some kind doing cartweels while we were soaking some live sards, right in front of us, in the mouth, and the sucker was bout 1 1/2 meters long. Had barra swimming past our feet at night, and the tarpon, after the sun went down, the mouth sounded like rapids flowing with all the tarpon chopping around. Just got them on fillets of garfish. The Anan is a real shallow river system, full of great bait. You can fish the anan for normal river fish, and then head out past the mouth and there is a fringning reef out there.
hope this helps a bit dave.
you'll luv cooktown.
Cheers
Dan
