A famous yet paradoxically little known location overlooking Wooloomoloo bay and near to the Botanic gardens. It was a popular swimming location with Indigenous Aboriginals before the arrival of Europeans in Australia. The pool was also the venue for the sporting triumphs of Australian swimming legend Andrew Boy Charlton in the 1920s and is believed to be the birthplace of the Australian Crawl or freestyle swimming stroke.

Andrew "Boy" Charlton Pool is an eight-lane outdoor heated salt-water 50-metre swimming pool on the shore of Woolloomooloo Bay in The Domain in Sydney, Australia, near the Royal Botanic Gardens. The pool is typically closed for four months in the colder period of the year - May through August. It was re-opened for the 2011–12 summer season, having undergoing a major refurbishment during 2011. In 1968, the pool, previously called the new Domain Baths, was renamed in honour of Andrew "Boy" Charlton, an Australian swimmer who won five Olympic medals during the 1920s. This pool is not to be confused with the Manly Andrew Boy Charlton Aquatic Centre, known as MABCs.
