Coady was in excellent form during qualifying for the star studded eight-woman final, landing in second place.
In the best of two run final under sunny skies, the NSWIS rider unfortunately fell on her first run, but put down a solid second run scoring 66.13 points to move into third place with one rider remaining.
But the last rider of the day Annika Morgan of Germany handled the pressure to score 80.75 points and finish in second place, which bumped Coady down into fourth.
Taking the win was American Julia Marino on a best score of 83.08 points, with two-time Olympic gold medallist Anna Gasser of Austria in third with 75.93.
Also in action for Australia was fellow NSWIS rider Meila Stalker who finished in 14th place and Valentino Guseli who had the two events in two different disciplines in 20th place.
In the men’s freeski slopestyle, Snow Australia skiers Cameron Waddell finished in 45th place and Kai Martin in 55th.
Coady is now in Aspen, USA, for the X-Games which will take place this weekend.
