Critters to see all year round are turtles, bull rays, eagle rays, woebegone sharks, hard and soft coral, nudibranchs and lots of different species of tropical fish. Julian Rocks also had a number of confirm great white shark sightings whilst diving over the years.

Our favourite Dive Plan

There are many options to dive and the dive plan often need to be adjusted to suit present environmental conditions such as currents or surface conditions. A great way to dive Julian Rocks is to start your dive at one of the western moorings such as the Nursery and finish the dive on a mooring on either the northern or southern side of Julian Rocks.

The Grey Nurse Sharks are often found in the vicinity of the Cod Hole (winter months only), around the 16-20m depth marks. Leopard Sharks can be found in large numbers around the Needles mooring during the summer months. There is nothing wrong with staying close to one mooring and to explore the immediate surroundings in more detail.


How to get there

Julian Rocks is only accessible by boat from either Brunswick Heads or Byron Bay beach. Sea conditions need to be reasonably calm to allow the bar crossing at Brunswick Heads and the beach launch dive boats from Byron Bay.
