Tribal Islanders would be better adversaries than smugglers because the smugglers would have guns and their numbers would be limited making for a short game Plus add Canabilism and an unknown number and things get interesting especially if they don't live on the island but one over the horizon

Well the smugglers wouldn't know we're there, we'd be the ones to find them and I'd like to think we'd know better than to pick a fight with them. Also, not all smugglers carry guns. In fact, a good number don't. It depends on the country they come from and how big the operation is.

EDIT: I do agree that islanders and cannibalism would be a great dynamic, along with nature just being nature
