Admired all over the world and loved by locals for its natural beauty, Sydney Harbour is enjoyed by thousands of people every day. But rarely do we look below the surface where, beneath all the hustle and bustle, lively communities go about their business. With underwater forests and gardens, hundreds of species of fish and thousands of invertebrates, Sydney is as colourful and diverse below the water as it is above!

Underwater Sydney celebrates Sydney’s incredible harbour and coast through eclectic stories and stunning underwater photography. It also explores the challenges the harbour is facing today after more than 200 years of coastal development and the role that marine science plays in maintaining the harbour’s health. Underwater Sydney will open your eyes to the rich marine life that makes the Sydney estuary and coast so special.
