Alex I have not fished for tuna other than Sydney. A few guys like ambition ,wahoo,alliehunter all chase tuna and do quite well but the seem to troll around more of times than just sight popping . I have done a few good hardcore season chasing these things and have only ever had 2-3 times where stick baits are taken . I suggest you take out your own block of pillies when fishing with these guys and once fish are Located on troll then start dumping pillies over to raise the fish . Once and if you can raise fish then pull out your stick boat rod.
Pm me if you need any more info from looks of things we are in with a good chance of some fish in 150kg mark this year
