The first bit of advice i'll give you is to join the local game fishing club, all the info you need will be available there as well as the option of fishing on other boats where the learning curve will be much steeper. I and many members on this site spend all summer chasing billies but conditions and styles may be differant up that way with regards the shows on the sounder you target and how you target them! I know down here you find the bait and stick with it at all cost but i've heard that sometimes up there this will only result in bycatch and more bycatch so a differant approch is needed! Smithy will be the guy to help you out i think as he deckied for a season up there last year as welll as fished the townsville comp!
