The eldest of five siblings, Cate, 24, will join sister Bronte, 22, at her third Olympics, after overcoming shoulder surgery last year to come out on top with big hopes for a world record. Cate has been training in the pool nine times a week, with three gym sessions for the past four years in preparation for the Rio Olympics.
Bronte beat reigning world champion and elder sister Cate at the 2015 FINA World Championships in the 100m freestyle. Fun fact: the sisters became the first family to stand on a podium together as individuals in swimming history. As our fastest swimmers in the 50m freestyle, all eyes will be on the star siblings.
