Emma McKeon is the most decorated Australian in Olympic history.

The New South Wales swimmer competed at the Olympic Games Rio 2016, winning three relay medals, including gold in the 4x100m freestyle relay alongside Brittany Elmslie, Brone Campbell, and Cate Campbell. She also took home an individual bronze medal in the 200m freestyle.

At Tokyo 2020, McKeon won four gold medals, including the 50m freestyle, 100m freestyle, and relay victories in the 4x100m free (including a World Record) and women's 4x100m medley relay.

She also took home bronze medals in the 100m butterfly, 4x200m freestyle relay, and 4x100m mixed medley relay taking her medal tally in Japan to seven - the most by any female swimmer at a single Olympic Games and the joint-most medals across any sport with Soviet gymnast Maris Gorokhovskaya.

McKeon's 11 Olympic medals overall broke the previous Australian record of nine from Ian Thorpe and Leisel Jones over the course of their careers.

In 2022, the 1994-born athlete broke the record for the most Commonwealth Games medals ever with six gold, one silver, and one bronze medals, bringing her total medal count to 20.
