Kitty Chiller competed in modern pentathlon at the Sydney 2000 Olympic Games before going on to be a Deputy Chef de Mission of the 2012 Australian Olympic Team (with swimmer Chris Fydler).
Chiller began competing internationally while studying at the University of Melbourne. Her first success came at the World Aquathon Championships (swimming and running) and she then joined her University fencing club which launched her modern pentathlon career.
Chiller spent almost a decade at the top of her sport, before female modern pentathlon was added to the Olympic program. She became a 12-time National Champion, seven-time World Cup medallist and six-time World Cup finalist. Chiller was ranked World Number One in the world in 1996, 1997 and 1998.
At the age of 36, Chiller competed at the Sydney Olympic Games, despite seriously injuring her knee cap the week before the Games, requiring a reconstruction afterwards. She placed 14th.
