We vary up here , saltwater species range from trevally, queenfish barramundi tuna mackerel snapper are the main ones but there many others susceptible to fly.(tarpon are here but they are tiny compared to what you have)Freshwater in the local billabongs amainly saratoga ( a lot of fun) and barra.
I often go to NZ to chase browns and rainbows so i will try for anything.Next year a friend and i are planning a trip to the Caribbean to try for the slam.
Flies here are mainly clousers and things( whistlers ) also gurglers or variations of these , not much sight fishing, the water is murky most of the time, we get tides up to 7 metres.
