That thought crossed my mind as well. I would be willing to float $600 US which is roughly $800 AU and others could split up the rest on a big game deep sea charter.
From what I understand from the website I visited, Tuna, Marlin, King Mackerel, Big Spanish and Yellowtail are killin it in April.
The charters I was looking at run about $1,400 up to ten people - $800 that about $100 a piece.
