In all nature parks (almost all over thailand it is highly illigal) You further more have to have a boat to get there and most dive operators will turn you in. They dont like you killing their fish. They need the fish for their clients. Even fishing is illigal in nature parks. Most divesites are in nature parks.. Bribing.. you can try but if it fails your in big shit.
I live in thailand dive a lot and talked to dive operators a lot
