Australian snowboarders Scotty James and Val Guseli have completed a historic one-two at the Laax World Cup super pipe event in Switzerland.

Two-time Olympic medallist James finished top of the pile after a phenomenal first run score of 94.00, while 18-year-old Guseli scored 92.25 in his second run to take the silver medal.

"Unbelievable the crowd here tonight, riding in this atmosphere under lights is a special feeling so to come away with the win tonight is pretty amazing," James said.

"Credit to the rest of the field, tonight was a proper finals, everyone brought their best and I had to bring mine.

"It was a lot of fun."

In arguably the best half pipe field ever assembled, the entire field pushed the limits of what was previously thought possible, with a number or riders landing triple corks that only emerged on the scene in the last two seasons.

"I'm stoked," Guseli said.

"It's always amazing … the energy is so great, in the air, hearing them screaming, it's an amazing feeling."

Last year, Gusli became the first person in snowboard history to win World Cup medals in all three disciplines in a single season, and the teenager continue to prove himself a triple threat by shocking the field with a first ever 1620 in a half pipe contest.

"I think those are some of the best runs I've done," Guseli said.

"I definitely wish I gave [the 1620] a little bit more and got it a bit cleaner, but it's always good to keep it improving and knowing where you can improve."

James, the oldest athlete in the field at 29 years old, said the progressions of the rest of the field helped to spur him on.

"The progression is pretty crazy," said James, who won his third Laax title after finishing second last year.

"Honestly, I'm on the edge of my seat all the time, but I like that, I like that competition.

"I'm pretty enjoying riding with the younger guys and they're pushing me and it's really cool to see where snowboard half pipe is going and to still be here is special and I look forward to seeing what happens next — it's gunna be exciting."

The victory is James' second of the half pipe season after he exorcised some demons at the 2022 Olympic venue in Zhangjiakou to win the first World Cup event to be held at the Secret Garden venue since he finished second to Ayumu Hirano.

Guseli said having James on the circuit was a real boost for both himself and Australia as a whole.

"Coming from Australia, we actually don't have 22-foot half pipe. It's so crazy<" he said.

"Being second to one of the best guys to ever do it and we're both from the same country, we can hold our flag up high.

"That's a beautiful thing and I'm super happy to be up there handing it to everyone with him."

Elsewhere on snow this weekend, Jakara Anthony extended her overall lead of the moguls World Cup by dominating the competition in the Canadian resort of Val St Côme.

Anthony, who had never previously won at the venue, backed up an individual moguls win on Friday night (local) with a second gold in the dual moguls.

That gives then 2022 Olympic champion a record eight gold medals from nine events in the 2023/24 season.

"It's getting a little tricky in there now," the reigning Olympic champion, Anthony said.

"I definitely think I came out and did some of my best skiing in qualifications, which isn't normally how it goes, but loving getting to ski out here on the course, it's pretty fun.

"It's my third World Cup here and first win, one place better than last year."

In the dual moguls final, Anthony engaged in a wild battle with American speedster and Olympic silver medallist Jaelin Kauf, who crashed heavily.
