Cahal,
There are several freshwater options around the southeast queensland corner for fresh water fly. With Hinze on the goldy, Maroon, Moogerah to the southwest, Sommerset, Wivenhoe, Cressbrook and Brisbane Valley to the west, North Pine, Lake McDonald, Baroon Pocket and Burumba to the north. These impoundments carry a population of Australian Bass, Silver Perch, Sartoga, Golden Perch, Mary River Cod and the humble Catfish. All of which will take fly.
Maritime Safety Queenslands " Beacon To Beacon" has important information on all of these locations including type of permits required and fish species on offer.
Another option is to attend a meeting of the Southeast Queensland Flyfishers held at the Mermaid Beach Bowls Club on the third tuesday evening of the month. The meeting starts a 1900. The members at keen on both salt and fresh water fly and will gladly lend a handto make your local flyfishing more enjoyable.
Jeff.
