She also combined with Dyana Calub, Petria Thomas and Susie O'Neill in the 4×100-metre medley relay to win silver, again behind the Americans. Jones left school aged 15 to concentrate on swimming. At the 2001 World Aquatics Championships in Fukuoka, Japan, Jones was now one of the established swimmers and expected to win medals. She finished second to China's Luo Xuejuan. The competition also marked her international debut in the 200-metre breaststroke, where she came fourth place (2:25.46). She also collected a gold in the medley relay alongside Calub, Thomas and Sarah Ryan, the first time that the US women had been beaten at world or Olympic level in this event, excluding the systemically doped East German and Chinese teams. In 2002, Jones claimed her first titles on the international arena, claiming the breaststroke double at the 2002 Commonwealth Games in Manchester, England. Australia also won the medley relay.
