Fast, powerful and superb on the plate, yellowfin tuna are one of Sydney's great offshore prizes. They roam the blue water wide of the coast, and hooking a big yellowfin means a long, grinding fight, and some of the best sashimi you will ever eat.
Torpedo-shaped and built for speed, the yellowfin tuna is unmistakable with its metallic blue-black back, silver belly and the long, bright yellow finlets and sickle fins that give it its name. They hunt in the open blue water, often with birds and bait marking the way, and pound for pound they are among the hardest-pulling fish in the ocean, capable of long, deep, punishing runs.
Yellowfin are found in Sydney’s offshore waters and run best from December to April, when the warm currents push in. Everything from school fish to genuine models over 100kg turns up off the coast, and beyond the fight, they are prized eating, rich, meaty and perfect for sashimi and steaks.

Yellowfin are chased over the blue water, and the method changes with how the fish are feeding.
The classic approach is trolling a spread of skirted lures and swimming baits along the current lines and temperature breaks where the bait holds. When the fish are up and feeding on the surface, casting poppers and stickbaits at the school is heart-stopping, visual fishing. We run quality game gear, and the crew works the spread and the fight from hookup to gaff.
Yellowfin follow the warm water and the bait, so finding them is about reading the ocean, the temperature breaks, the current lines, the birds and the bait schools. George Aslanian has decades chasing tuna off Sydney, and he knows the runs and the timing. We put you over the fish, coach you through the long fight, and help you look after your catch for the table. Ready to go? Book a Sydney game fishing charter.
