Pullin was the flag bearer for the Australian Winter Olympic team at the 2014 Winter Olympics in Sochi, Russia, and competed in the men's snowboard cross. One of the favourites in that event, Pullin was eliminated in the quarterfinals. The Australian government had given Pullin $500,000 in funding for the event, more than any other Australian competitor. At the 2018 Winter Olympics, Pullin again competed in the Men's Snowboard Cross and came in sixth place, having crashed out during the final race. He was the number one ranked competitor in the event according to the world rankings prior to the Games. Fellow Australian Jarryd Hughes came second at the event, but Pullin did not congratulate him due to a personal feud between them.
