In Athens, Jones was again the quickest qualifier of the 100-metre breaststroke, after setting an Olympic record (1:06.78) in the semifinals, which was almost two seconds clear of the then second fastest swimmer in the event's history, Amanda Beard. However, in the final race she finished in the bronze position. In the 200-metre breaststroke, she attempted to take an attacking approach, but faded in the last 50 metres and was pipped to the wall by Amanda Beard, winning silver. Australia went on to win the 4×100-metre medley relay, giving Jones her first Olympic gold.
