Shelling adventure of a lifetime suggestions?

My favourite would be any of the little known Pacific islands and Atolls, they would be great as many have never been collected on so you never know what you will find.  The usual places like Maldives etc. have been done to death, everyone knows what is there and what to expect. Much better to explore somewhere that nobody has collected in before and make amazing discoveries, maybe even find new species.
