Nick Hocking is joined by specialist fly fisherman David Bell in this episode of Fishing Western Australia, as they cast a fly for Trevally, Queenfish and anything that will bite in the Mackerel Islands. Saltwater fly fishing is among the most exciting forms of the sport around the world. The crystal-clear, shallow waters of the Mackerel Islands offer a population of fish so abundant that Nick and David may as well be casting into and aquarium. With no particular quarry in mind, the boys encounter Queen Fish, Chinaman Fish and a variety of Trevally species, with a few massive specimens on the cards. This episode is a perfect example of the never-ending variety of species off the coast of western Australia.
