Diving in Byron Bay
All diving in Byron Bay is boat diving, as most sites are a few minutes boat journey offshore. Many of these sites have shallow maximum depths, ideal for beginner divers. The reefs here are healthy and stunning, carpeted in hard and soft corals, sponges and anemones, which act like a magnet to the abundant reef fish. Warm and cold water currents combine to bring the diverse mix of cold water and tropical fish found here.
