I think the most important things to remember are not to overpack and to take comfortable clothes. Maybe a nice shirt or two for pictures and other than that, take comfortable clothes.
Good advice. earlier this year, I spent 2 weeks hunting and fishing in the NT of Australia, and took only a carry-on of 15 lbs. Borrowed hunting rifle from the PH, used the fishing gear supplied by the captain. Was able to have short lay-overs/plane-changes, and had enough clothing.
