The sixteen-year-old NSWIS Snowboarder impressed early, securing a direct path to the six-woman-final, after advancing in second place from her heat in the qualifying stage.
In the final, competitors had three runs with the best score counting for the overall ranking. Coady's first run score of 68.88 was her best, giving her a final placing of sixth, equaling her result from the first start of her World Cup career in Mammoth Mountain, CA, USA, in early February.
The event was won by another 16-year-old, with New Zealand's Zoi Sadowski Synnott claiming her first ever victory.
Rounding out a strong debut season, Coady also recently competed at the 2017 World Championships in Sierra Nevada, Spain, where she placed 11th in Slopestyle and 21st in Big Air.
Coady will now remain in the Czech Republic to represent Australia at the Snowboard Junior World Championships this weekend.
