Jarryd Hughes and Belle Brockhoff have clinched Australia's first-ever World Championship gold medal in the snowboard cross mixed teams event in Sweden.
The new category is a two-competitor-per-team relay with one male and female athlete, and will be introduced as an Olympic event in Beijing next year.
The male athletes race first, with the women leaving the start gate with the respective time margin that the men cross the finish line.
In the medal round, 2018 Olympic silver medallist Hughes got Australia off to a great start in the final with impressive riding to cross the line in first place, 0.77 seconds ahead of the Italian team.
Multiple World Cup winner Brockhoff then raced exceptionally well to take the victory, finishing 0.64 seconds ahead of the Italian team with France crossing the line in third place.
"Well, this is as good as it gets," said 25-year-old Sydneysider Hughes. "We haven't raced in a team event before ever.
"We knew we could do it and we were really confident in our abilities, then we just set out a really good game plan among the two of us and maximised our strengths and I am just lucky to have had such a strong rider like Belle to be riding with."
Brockhoff was equally excited.
"I am really stoked to be here, especially after yesterday's fall, it's a bit of a redemption, so I am very happy and very excited," the 28-year-old from Melbourne said after stepping off the podium.
The snowboard cross athletes will now head to the Swiss resort of Reiteralm for a World Cup event on February 18.
