The inaugural Marilyn Jetty Swim was held as part of the 2014 Brighton Jetty Classic. Since then it has become a crowd favourite with thousands cheering them on from the Jetty and shoreline.
2023 saw the biggest group of Marilyns to date, with over 500 Swimming and Shore Marilyns adding to the spectacle. In 2023 they surpassed $1,000,000 raised to help support South Australians impacted by cancer and the Cancer Council.
