You'll notice from that post above that the Blacks up in Cairns are bigger fish then I mentioned previous, down around the Sunny Coast and Goldy you won't get them that size, they'll be much smaller then the Blues. If you want a once in a life time fish here in Oz then Cairns is your best chance of getting it which is why I recommend there in my first reply, you can get big fish elsewhere, but not in the numbers that Cairns has them.
