Kennedy-Sim had a great few days on the sprint track in Arosa, qualifying for finals in first place, winning a bronze medal in the first competition, her first World Cup podium since 2017, and a sixth place finish on day two.
In the round of 32 and 16, Kennedy-Sim advanced through her heat in second place to reach the semi-final stage.
Kennedy-Sim was unable to reach the medal round, finishing in fourth place in the semi-final, which put her in the small final to decide places six through to eight. Finishing in second place gave her a final position of sixth.
Also in action for Australia was Doug Crawford, who finished in 49th place.
Kennedy-Sim is currently ranked third on the world cup standings on 100 points, trailing Fanny Smith of Switzerland who leads with 180 points and Swedish skier Alexandra Edebo on 136.
