Dive Site in Byron Bay: Cod Hole

The Cod Hole is an underwater swim through around 30 metres from the north-eastern tip of the Rocks. The hole opens at a depth of around 15 metres and slopes down to a depth of 21 metres. Moray eels, blue groupers, wobbegongs and grey nurse frequent this spot.


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.


Dive Site in Byron Bay: Hugo’s Trench

This dive spot has sheer walls on either side of the trench, and is frequented by wobbegong sharks, turtles and schools of fish. At a depth of 12 to 18 metres, the trench runs through the rocks, but conditions need to be perfect to attempt a swim through.
