Matts has an cool CD you can use to measure distances. I use it all the time to calculate fuel requirments. worth its weight in snapper fillets!!
Fished heaps in bynoe, options are endless. happy to walk you through it in detail but here are some snippets -
tapa bay mouth
rock bars just north of Raft Point
main creek just behind turtle island
the bynoe ledges see FF book
crab claw wreak is sweet
deep gutters opposite pearl farm, rankin point i think it's called.
Simms goes off also the drains off the reefs behind it(Grose island) on super springs, cast for all sorts of stuff
all depends on the tides of course. hope this helps
