Originally an artistic gymnast, she studied information technology at Swinburne University of Technology in Melbourne. Inspired by the achievements of three-time Olympian Kirstie Marshall , she also wanted to become a freestyler, although she could not ski at all. For this purpose she turned in 1994 to the "Olympic Winter Institute of Australia". She trained her jumps in a small lake in Wandin, a suburb of Melbourne. She has suffered numerous injuries over the course of her career, including a broken collarbone, broken hand, and nine concussions.
Before the 2002 Winter Olympics in Salt Lake City , she had some top 10 placings in the Freestyle Skiing World Cup , but still no victory. Her compatriot Jacqui Cooper was a big favorite, but she suffered a knee injury a week before the Olympic competition. Quite surprisingly, Camplin won the gold medal. She later testified that the surprising Olympic victory of short track runner Steven Bradbury had given her wings. Four days after the victory, on February 22, 2002, the Australian Post issued a 45 cents stamp in her honor . The successes of Camplin and Bradbury sparked a winter sports boom in Australia.
At the Freestyle World Championships 2003 in Deer Valley , Camplin proved that her success was no accident by winning the world title. In addition, she won 10 World Cup competitions (status: end of February 2006) and won the World Cup discipline in the 2002/03 and 2003/04 seasons.
In October 2005, she suffered a serious knee injury. To accelerate healing, she resorted to an unusual method and had a donated tendon implanted from a deceased person. Just eleven weeks after the operation, she resumed training and qualified for the 2006 Winter Olympics with fourth place in the World Cup competition in Lake Placid . She carried the Australian flag into the stadium during the opening ceremony. At the Olympic competition in Sauze d'Oulx , she won the bronze medal behind the Swiss Evelyne Leu and the Chinese Li Nina .
