    StandoutExceptional marine biodiversity

    The Sewage Pipe, off Sydney’s northern beaches, offers a straightforward shore dive, popular with locals for easy access. You'll find wobbegongs tucked into the pipe's nooks and crannies, alongside eastern blue gropers and cuttlefish. It’s a reliable spot for macro life too, if you take your time. This site suits divers looking for a relaxed, self-guided exploration, particularly when conditions are calm.
