It was an impressive performance from the 21 year old, who placed seventh at the Sochi Winter Olympics back in 2014.
Graham finished with a total score of 87.74.
The event was taken out by Canadian Mikael Kingsbury, with countryman Laurent Dumais third.
Fellow OWIA athlete Brodie Summers finished in 27th place, while NSWIS athlete Rohan Chapman-Davies came in 32nd position.
In the women’s section, Britt Cox also put in an impressive display finishing seventh, narrowly missing out on qualifying for the Top 6 Super Final by 0.28 points.
In a remarkable result, the top three places in the women’s final were taken out by Canadian sisters, Justine, Chloe and Maxine Dufour-Lapointe.
After the presentations, Graham reflected on his great performance.
"I am very happy with how today went," Graham said. "I had to lay down a really solid final run in order to make the super final, so to get back on the podium has given me a lot of confidence going into Calgary and Deer Valley over the next two weeks."
OWIA Mogul Skiing head coach Steve Desovich was also delighted with Graham’s performance.
“Matt continues to demonstrate outstanding quality in both his jumps and turns and he is being recognized now for his superb skills,” Desovich said.
"Britt had a very nice run and just needs to improve a bit in every area from turns, to jumps and speed,” Desovich added.
