The Blue Devil Cave is in approximately 18m of water. It gets its name from the main resident of the small cavern- an eastern blue devil fish. There are also other regular visitors other than divers, like a giant cuttle fish or wobbegong shark. There are also spiders crawling around the place and and some times there is a weedy or pipe fish near by! It is always exciting going to the devil cave because you never know what you are going to find!
