Our Harbour is an ecosystem wonderland, with over 3,000 marine species doing their thing in our waters, including more than 600 types of fish. Swimming with that kind of biodiversity sounds cool, but finding the right spot can be tricky.

In the past year the Marine Rescue NSW team dealt with over 670 people who found themselves in trouble around Port Jackson (which includes the harbour). Boaters, kayakers, and paddle boarders are constantly getting swept off their vessels or slipping into the water.

It’s mainly dangerous because Sydney Harbour is a transit zone for everything from small ferries to colossal container ships, commercial boats, tugboats, and cruise ships. If water traffic doesn’t stop you, the water quality might.

The City of Sydney admits pollution is the number one issue that’s stopping the harbour from becoming the swim-friendly destination many locals dream of, even netted swimming areas are sometimes off-limits after a storm. Legally, Sydney Cove, which sits between the Sydney Harbour Bridge and the Opera House, and Farm Cove are off-limits for swimmers. If you’re caught in the water, you could be slapped with a fine of up to $1,100. A hefty price for a pretty gross swim.

Where can you swim in Sydney Harbour?

The good news is that there are a few spots where swimming is allowed and actually encouraged. First up, Marrinawi Cove at Barangaroo, which opened a little over a year ago, is the only netted swimming area in the actual harbour. It’s the one place where you can cool off without worrying about being run over by a ferry.

If you’re looking for a proper beach experience, Little Manly Beach is a solid choice. With its calm waters and prime views of Mosman and the eastern suburbs, it’s the perfect spot for families and solo swimmers alike. Pro-tip: stick around for the sunset—it’s worth it.

Then there’s Maccallum Pool, a gem on the western side of Cremorne Point. The pool’s wooden boardwalk and vintage charm make it feel like a step back in time, but with uninterrupted views of the city and the harbour’s finest yachts. Just get there early—it’s small, and it fills up quickly on hot days.

For those who prefer a more secluded spot, Northbridge Baths are tucked away on the edge of Middle Harbour, surrounded by bushland and sprawling waterfront homes. This tidal bath is perfect for families, with a jetty for jumping, BBQs, change rooms, and ample parking.

Nielsen Park is another great option. Known for its heritage status and beautiful views across the harbour, it’s a local favourite for picnics and swimming, and best of all it’s got a shark net.

If you’re after something a little more low-key, Camp Cove offers calm waters, plenty of space for the kids, and grassy areas perfect for chilling with a book. Watsons Bay Boutique Hotel is just around the corner, making it easy to transition from a day in the sun to a night of cocktails.

Making Sydney Harbour swimmable

The City of Sydney does have plans to improve water quality and make more of the harbour swimmable, but it’s not as easy as throwing up a few shark nets. There are years of pollution and outdated sewage systems that need an overhaul. The council has been working with Sydney Water to fix the water quality, but it’s going to take time—and a lot of cash.
