Yes, the resort on Sangalaki itself has been closed, apparently for conservation reasons (sounds like what's happened at Sipadan?), so no more development on the island. I was told it has a permanently manned guard-post and turtle conservation unit there.
I love it. Since when is turning a dive resort into a commercial fishing base good for conservation? Don't get me wrong, I am not criticizing you as you can only check what is available in the news. According to to someone who was on the ground there, fishemen have taken over the island and trashing the place to an extent that it is hard for turtles to get up on the shore. I doubt any eggs that do get laid survive any poaching and I doubt the fishermen will move on until the fish are gone too. Selamat datang ke Indonesia.
