Snowboarder Scotty James will chase Australia's second medal of the PyeongChang Winter Olympics when he faces off with American legend Shaun White in the halfpipe final.
James qualified second for the final, 1.75 points adrift of No.1 White who took the lead with 96.75.
"I expected to Shaun to come out and put a run down like that," James said. "I watched his run - it was a good run - it had good amplitude and was pretty flawless."
James hinted at having something more in the bag for the final but wouldn't give too much away.
On Tuesday he didn't use the switch backside double cork 1260, the trick that has caused some consternation because James is the only one who does it and believes he should be scored accordingly.
At least one judge may be on his side come Wednesday, telling AAP on condition of anonymity that he felt James boasts the most difficult trick in the competition.
Elsewhere, Great Britain's Elise Christie suffered further Olympics disappointment on a day when Austria's Marcel Hirscher ended his wait for gold with victory in the men's combined.
Christie, world champion over 1000m and 1500m, crashed in the women's 500m final.
The 27-year-old Scot's Games agony goes on after her triple disqualification in Sochi four years ago.
Italy's Arianna Fontana took gold, Holland's Yara van Kerkhof silver and Canada's Kim Boudin was upgraded to a surprise bronze.
Hirscher has six world titles and 55 World Cup wins, but had just one Olympic medal from two prior Games, with slalom silver in 2014.
The 28-year-old was triumphant at Jeongseon Alpine Centre, placing seventh in the downhill, before overhauling his 1.32-second deficit in his favoured slalom event to win by 0.23.
Alexis Pinturault took silver and fellow Frenchman Victor Muffat-Jeandet bronze.
"I'm super-happy because now this stupid question is gone away," Hirscher said.
"If I'm thinking that my career is perfect without a gold medal, now this question is zzz, deleted."
Canada won the mixed doubles curling, beating Switzerland 10-3 in the final. The Olympic Athletes of Russia pair took bronze.
