Marty, 24, will compete in downhill, giant slalom, slalom and super G events at the games in Vancouver from March 12 to 21.
With other members of the Australian team, he went to Colorado in the US before Christmas for training before going to Austria earlier this month.
A team spokesman said his form in World Cup events there so far had been encouraging and there were high hopes for him at Vancouver.
Marty, who had both legs amputated below the knee when he contracted meningococcal aged 16, competed for Australia at the 2006 Paralympic Games in Torino.
While he didn’t make the dais at those games, the team spokesman said his progress since then had been ‘massive’.
He won a gold medal in slalom at the 2007 World Cup and a bronze medal at the 2008 World Cup.
Marty is completing a health science degree and hopes to study medicine and become a doctor.
