About this site
Under the Tube is a wall dive on the north-east corner of Moon Island, named for the wave that forms above it when a swell is running.
Rocky reef drops from 12 to 22 metres, with sand at the base. One of the highlights is the Slot Cave, and there are walls and further caves to explore.
The site is also known as one of the best areas around the island to find Eastern Blue Devilfish.
