I live about 20 minutes north of port, by the daintree river, most guys target Barra in the inlets with lures and live prawns, I'm a spearo but have line caught good sized mangrove jack, black bream, queenfish, and mackeral in the inlets and headlands. The fish life on the coast for spearfishing is awesome, as is the inner reef. August will probably be windy as,
But you can fish the inlets no worries, lots of charters up here working the inlets.
