Geiger began skiing at the age of two in Austria, and made the national team in 2006. He won numerous Australian Championships during his teenage years, and represented Australia at the 2008 World Junior Alpine Skiing Championships and the 2009 FIS Alpine World Ski Championships. This changed after his 2009 accident. "I tried to get back to able bodied [competition] but couldn't quite get back to where I was, let alone where I wanted to go," he later explained, "so I had to hang it up."
