"Some goblin laboratories on the two islands south of Tanaris during alpha, these buildings was later removed for the retail version and replaced with pirates instead."
"For those who made it past the fatigue area between the islands and Tanaris, there was a bottle with a note buried in the sand, waiting for them at the first island.The note said "What the heck are you doing here?", but that one got also removed shortly after and the only remains is a circle formed shadow of the bottle in the sand."

It appears that the purpose of the island has changed throughout the game's release process. What remains today is little more than a rather bland island that presents a challenging swim.
The southernmost islands off the coast of Tanaris remain in the game, however, the content has changed throughout the release of the various patches, leaving little more than a couple (difficult to reach) islands with some pirates and scorpions.
