In Sydney, a pool is more than just a place to swim – it’s an icon, a meeting point and a snapshot of the city’s unique character. It’s also a place where people can relax and get away from the busy pace of life. And that’s why the community is so passionate about keeping them open.

The City of Sydney is hosting a summer open day to give Sydneysiders free access to 6 outstanding pools. Head to Andrew (Boy) Charlton Pool in Woolloomooloo for sweeping harbour views and a bite at the recently reopened Oh Boy cafe or take a dip in Cook + Phillip Park Pool in the heart of the CBD near St Mary’s Cathedral. There are plenty of other activities to keep you active too like yoga and health and wellness talks.

It’s no secret that swimming is good for you, but the fact that it can help prevent cardiovascular disease, lower blood pressure and strengthen bones and muscles is an added bonus. It’s also a great way to relieve stress and have fun with friends. That’s why we’re urging people to visit their local pool this summer and take advantage of all the benefits that swimming has to offer.

While Australia has many stunning beaches, some are too wild to swim safely. Across NSW, there are more than 100 ocean pools that were built in response to the need for recreational and competitive swimmers to have a safe place to train, away from the powerful surf and the danger of shark attacks. Some of these pools are more than a century old. ABC News has been exploring their history, and we’ve put together a list of the most iconic.

Bondi Icebergs

For some, Bondi icebergs is the ultimate Sydney rockpool experience – it’s sort of like swimming in the harbour, only much colder and less clear! You can sit on the cliffs and warm up by dipping in the water, hang out in the sun or imagine yourself in one of those summery coming-of-age movies.

Bronte Baths

Built in 1887, the Bronte Baths are a little south of Bondi Beach and part of the popular Bondi to Bronte costal walk. You can swim in filtered seawater or chill out on the rocks as you soak up the views of the iconic beach. Or you can join the brave regulars who challenge themselves to swim in the icy water.

The City of Sydney’s ocean pools have a long and proud history. The opening hours of some are set to be reduced this summer as cash-strapped councils cut back on costs. But experts say that’s a risky move, with drowning rates on the rise nationwide.
