Great holding in 5-8m on sand and light seagrass. A bit rolly, particularly further out in the bay. Be sure to snorkel through the anchorage to admire the beautiful large and very placid turtles as they feed. If you are lucky you may well spot a dugong also. Sadly the reef here is in a rather rough state as is riddled with Crown of Thorns starfish.
A ship in harbor is safe, but that is not what ships are built for.
