Titmus's victory marked her second consecutive Olympic gold in this event and made her one of only two Australian women to achieve back-to-back titles, alongside Dawn Fraser. Additionally, the Australian women's 4x100m freestyle relay team, consisting of Mollie O’Callaghan, Shayna Jack, Emma McKeon, and Meg Harris, set an Olympic record by finishing in 3:28.92, securing gold ahead of the USA and China. The U.S. men's team, led by Caeleb Dressel, clinched gold in the men's 4x100m relay with a time of 3:09.28, marking their third consecutive victory in this event. In rugby sevens, France stunned Fiji with a 28-7 victory, securing gold in a thrilling match led by Antoine Dupont. Overall, Australia's swimming team looks to build on this success as they aim to match their record performance from the Tokyo Games.
