One of the most successful players in the game's history, she captained Australia at the 2008 Beijing Olympic Games, where she became the first person to play 300 games for Australia. In total she played 303 games for her country and scored 99 goals.
She made her debut with the Hockeyroos aged just 17 and has played in three Olympic Games, three Commonwealth Games and three World Cups, collecting four gold medals from the most prestigious events in the game.
Her No.1 career highlight was a gold medal at the 2000 Sydney Olympics, where she was the tournament's leading goal-scorer. She further enhanced her international standing when named captain of the World XI by the International Federation of Hockey in 2006.
She has also earned two gold medals from the highly regarded Champions Trophy, and was rarely part of a team that has finished any international competition lower than third place.
