Mark from Brisbane,
As someone previously posted, there's sugar produced in the Ord around Kununurra, now I'm not sure if you're a Rum drinker, but if you are, there's 2 distilleries in the area.
I've heard some good reports, so it might be worth trying, just so you can keep the chill off your bones during those frigid dry season nights, of course.
And watch out for the swamp dogs when you're fishing up that way; they'll hunt you if you use the same spot a few times and give you a very, very nasty nip.
