The Gardens is a reef site located off the Western Port Bay side of Phillip Island, Australia. This boat-accessible dive features depths ranging from 6 to 19 metres, with an average depth of 13 metres. The site is exposed to open ocean conditions, resulting in moderate currents and surge that require advanced buoyancy control and situational awareness. Due to its exposure, the site is only diveable during periods of very calm swell. Divers should plan their visits around slack tide to manage the current effectively. While the site is suitable for snorkelling, the variable conditions and potential for strong currents make it best suited for experienced divers.
