Dive Byron Bay’s Julian Rocks Marine Reserve. Julian Rocks is one of the few dive sites where you can swim with tropical species found on the Great Barrier Reef as well animals from Australia’s deep Southern Ocean. The course includes equipment hire, one swimming pool lesson and one dive at the Julian Rocks Marine Reserve with a qualified scuba instructor. All confined water training is conducted at the dive shop, an instructor training facility, located in the heart of Byron Bay. Here there is a fully equipped classroom and a training pool heated to 25 degrees Celsius. All open water-training dives are boat dives conducted at Julian Rocks Marine Reserve. Here you will swim with tropical species such as turtles and manta rays, as well as many interesting southern ocean animals including friendly blue gropers and wobbegongs. All this only a five-ten minute boat ride from Byron Bay.
