Dive Type: Shore Dive | Experience: Advanced

Sydney residents would be aware that the waters around Sydney that were previously severely polluted by sewage are now much cleaner. At the time of writing, there are only two main sewerage outlets that still pour sewage into the ocean, these being located at Potter Point near Cronulla and Diamond Bay near Vaucluse. The three main sewage treatment works at Malabar, North Head and Bondi have all now switched over to the disposal of the effluent through deep-water ocean outlets that deposit it three to four kilometres off-shore.

The final treatment works to come on-line was the Bondi Sewage Treatment Plant. Prior to its connection in July 1991, the North Bondi and Flat Rock dive sites could only be dived in the right weather conditions when the sewage was blown away from the dive sites.
