Sydney is well-known for its surf, but beyond the wild waves are sheltered harbour coves and shallow, secluded bays where an incredible variety of sealife flourishes. Seeing some of Australia’s most unique and iconic marine species can require nothing more than a mask, a snorkel and knowing where to look! These 10 sites, from Ku-Ring-Gai in the far north to the Royal National Park down south are protected from swell in most conditions and only a few metres deep, making them perfect for beginner snorkelers and experienced, duck-diving critter-spotters alike. Do yourself a favour and see Sydney from below the surface - this big city is bountiful with nature's beauty and full of surprises.
