COD HOLE

Dive Site in Byron Bay: Mohole and Line of Smiles

Is a small cave at the southern end of the Needles in about 14 meters depth. Typically, you’d see a huge Loggerhead Turtle sleeping in there. The Mohole is always worth checking out, you could see big cods getting cleaned, massive Bullrays followed by a school of cobia, huge schools of big Kingfish in a feeding frenzy, never a dull moment. The Line of Smiles is just a short swim from the Mohole, it is a huge crack in a rock wall which is filled to the top with all sorts of interesting Marine Life. Swimming past it, at first glimpse all you can see is a line of Wobbegong Sharks squeezed in there on top of each other looking out which is where the name “Line of Smiles” comes from. At closer inspection (but watch out for those wobbies!), you can see crayfish, Blind Sharks, hundreds of Cleaner Shrimps and little crabs and the occasional Nudibranch or cuttlefish.
