Also, buying an island in a 3rd world country is an entirely different proposition from doing it in a place like Canada. For example, keeping your stuff safe becomes a major concern, especially if you're planning to only visit every now and then; you pretty much need to hire a permanent caretaker.

Also, in the Phils (and most all Asian countries) foreigners can't buy land directly, so you need to use various workarounds of dubious legality like setting up a corporation with a local citizen as director and an undated, presigned letter of resignation, etc.

And you're still screwed if somebody in power doesn't like what you're doing. There was a bizarre case a while back with some Finnish guys setting up camp on a remote Indonesian island (with go-ahead from the locals, mind you) that eventually ended up with the army showing up to kick them out with lots of chest-thumping about Indonesian sovereignty, but my Google-fu is failing me right now...
