When the water cools, the southern bluefin arrive. These powerful, deep-bodied tuna are among the hardest-fighting fish in the ocean and the ultimate cool-season prize off the NSW coast, brutal on the tackle and second to none on the plate.
Deep-bodied, thick-shouldered and built like a torpedo, the southern bluefin tuna is a true heavyweight, a metallic blue-black back over a silver belly, short pectoral fins and a body packed with muscle. They are cold-water hunters that move up from the south in the cooler months, and when one loads up the reel it delivers a long, deep, grinding fight that pushes angler and gear to the limit.
Bluefin run best from May to September and are found along the NSW south coast when the currents are right. As a regulated species they come with strict rules, so we always fish to the current NSW DPI regulations. For the angler who wants a genuine heavyweight and superb, rich sashimi, the bluefin is the one.

Bluefin are a cool-season fish, and getting one to the boat is a genuine test of angler and tackle.
Bluefin are targeted by trolling skirted lures and swimming baits along the current lines and temperature breaks, and by dropping live baits when the fish are holding. Hook a good one and settle in, these are deep, dogged fighters that do not give up easily. We run heavy game gear built for the job, and the crew works the spread and the long fight from strike to gaff.
Bluefin move with the cold water and the bait, so timing and reading the ocean are everything. George Aslanian has decades of experience chasing tuna off the coast, and he knows when and where the bluefin run through the cooler months. We put you on the fish, coach you through one of the toughest fights in fishing, and help you look after a catch that eats as well as any tuna going. Ready to go? Book a Sydney game fishing charter.
