This trip was just over $7,000, ex Darwin. Those prices were based on when this group locked in dates more than 12 months ago.
I think I heard that the same trip next year will be over 8k - but they might have been talking about a different trip/region.
Booze is the only extra. (And any gear you borrow from the boat or the guides is on a 'replace if lost/broken' deal.)
- On that note, after the 2 trolling rods broke I borrowed a 5'8" Tairyo Nano Speed 4-6kg rod to troll and it punched well above it's weight.
