Torah Bright is testing the waters for an Olympic assault on two disciplines as she competes in the slopestyle event at the world championships in Quebec.

Bright, the 2010 halfpipe gold medallist in Vancouver, skipped her pet event at the Stoneham resort and instead is concentrating on the new Games discipline.

It is understood Bright is using the competition as another measuring stick against the top level riders and will pursue both disciplines at Sochi 2012 if good enough.

Australia's Olympic Winter Institute boss Geoff Lipshut said Bright had even spoken about competing in the snowboard cross, though the more race-focused discipline would be something of a stretch even for a rider as talented as the 26 year-old.

But success in the halfpipe-slopestyle disciplines at the one event isn't unheard of, champion men's snowboarder Shaun White twice winning the double at the X Games.

Slopestyle qualifying was expected for the women's event on Friday (AEDT) but Bright will have to cool her heels until Saturday with high winds forcing the postponement of the event.

Bright, who was a modest 55th at a low-key World Cup event earlier this month, is one of 18 Australians at the snowboard world championships in Canada, the team with three defending champions - Nate Johnstone and Holly Crawford in the halfpipe and Alex Pullin in snowboard cross.

Johnstone recorded perhaps the best result of his career last weekend when he won a World Cup event in a strong field that contained many of the Americans who usually skip the generally weaker cup circuit.

Pullin, who had an exceptional 2010/11 season in which he claimed the world and overall cup crowns, is also coming back to form.

He has a fourth and a second from his two World Cup events following a difficult 2011/12 season.

"It's feeling a bit similar to how I went into the last world championships, with some solid results in the lead up," Pullin said.

"But hopefully again it will be a case of leaving the result for the right time - that is for the world championships.

"Last year definitely wasn't what I was after results-wise but I got a lot of things out of it like my equipment ... which has enabled me to push my technique further."

Meanwhile 18-year-old Australian Britteny Cox scored a podium finish in World Cup moguls skiing in Lake Placid in the United States on Friday.

Her third place marked her second World Cup podium.
