No prob, I just got up from my afternoon nap, so good timing...
how much time you got in BNE, I actually work at the airport (domestic), and Jason's shop is only 10 minutes down the road.
I'm sure if time is a bit tight, something can be arranged.
Also, who you diving with in PNG? If its MV Golden Dawn, last I heard, they had sorb on the boat... Any others, and have you specifically asked if they'll let you take your breather?
