Mack tuna, frigates, and bonnies are all common around headlands in warmer and autumn months, when kayak fishing for bigger stuff, aka mack tuna, I tend to fish a few hundred metres off headlands, throwing bigger lures and throwing out an unweighted whole ganged pillie and leave it drifting about. Also, a flashy 60gm jig can also attract the above species.
A decent mack tuna on 25lb spin gear is good fun but a bit sketchy, probably not in a yak though
