Longtail tuna are hard-fighting speedsters that get plenty of Aussie anglers excited, especially when they start busting up on bait. They pull well above their weight, eat clean, and can turn a quiet session into chaos in a hurry.
In Australia, longtails are most common along the northern half of the country and down the east coast, working coastal waters, headlands, island edges and big bays. You’ll often see them inshore compared with other tuna, especially around bait schools, current lines and pressure points near river mouths and reefs.
They mainly chase small baitfish like herring, anchovies, hardyheads and pilchards, and they’ll also smash prawns and small squid when the chance comes. Longtails hunt fast and high in the water column, often rounding bait up and feeding in short, aggressive windows.
Tide matters most where current concentrates bait, so the better bite usually lines up with the run rather than slack water, especially around headlands, channels and harbour mouths. Low light can help a lot, with dawn, dusk and overcast periods often getting fish moving closer and feeding more confidently on top. Light to moderate wind is usually ideal because it gives the surface a bit of texture without making it hard to spot working birds or surface bust-ups. Smaller, manageable swell is generally better for inshore longtail fishing, as too much swell can dirty the water, spread bait out and make feeding less predictable.
A 7–8 foot spin rod with a 4000–6000 size reel, 20–30 lb braid and a fluorocarbon leader is a solid all-round setup. Cast metal slugs, stickbaits and small soft plastics into surface action, or slow-troll small bibbed minnows and rigged gar when fish are moving but not showing much. Keep leaders neat and lures small when they’re fussy, because longtails can get very selective on tiny bait.
Longtail tuna are one of the few tuna species regularly found well inshore in Australia, sometimes feeding within casting distance of the beach.
