Hall’s 18th place was a World Cup career best result for the Perisher based athlete since debuting in February 2009.
He was unlucky not to qualify for the final, missing the 16-man cut by just 0.7 of a point.
Australia's highest ranked mogul skiers, Britteny Cox and Matthew Graham, both 18-years-olds, finished 19th and 23rd respectively.
Cox’s desire to make her fourth final from six starts suffered from a lower than preferred score with turns, however, she can be pleased that her speed down the hill, one of the areas she has been working on this year, was impressive.
Fellow AIS / NSWIS skier Nicole Parks also had a tough day in 34th, while NSWIS athlete Taylah O’Neill did not finish.
