Hey Ozbee,
I'm up in Cairns and I don't know of anyone that runs a charter that far out in that depth, because the amount of run/current is unbelievable. Up off Port Douglas, we have fished in the 80m plus depth and got some good big mouth and red emporer.
On one occassion we were out and seen a bloke fishing out wide and we pulled up next to him and had a chat and he was in about 130m from memory and was catching big mouth massive size. We tried to hook up but there was just too much run that night. But he said he was having a few dramas with sharks giving the fish a touch up that night.
You could expect to catch anythign in that depth, just a matter of holding the bottom.
