Consecutive winter Olympic gold medals appear to be in reach for Lydia Lassila, the aerial skier showing some of her best form to win her first World Cup event in four years in Canada on Tuesday.

It was a red letter day for the Australian contingent at the Quebec resort of Val St Come with David Morris capturing his first medal for the season, a bronze, while Samantha Wells was fourth and Renee McElduff eighth.

Lassila hadn't topped a World Cup podium since January 2010, with the Victorian going on to take gold at the Vancouver winter Olympics a month later. She took two years out of the sport to start a family and, before Tuesday's victory, had four runner-up finishes in the two years since her comeback.

But she delivered spectacularly in the four-woman super final, landing a difficult triple twisting triple somersault to finish ahead of China's Nina Li and Xin Zhang.

''I have had some podium finishes and great performances but having a win is definitely more special,'' Lassila said from Quebec.

''I am just really happy with the way I won. It was fair and square and I was doing a higher degree of difficulty than anyone else.''

Lassila would like to land a quad-twisting somersault in time for the next month's Games - but admitted her winning jump on Tuesday was tough enough.

''It was quite taxing for me and takes a lot of energy and I am still nervous about it but the only way to get through them is to do them,'' she said.

The other bonus for the Australians was the conditions; unlike the frigid temperatures of recent weeks in North America, it was warmer and wetter much like Sochi is likely to be.

Morris said he still had plenty to work on after finishing behind winner Liu Zhongqing from China and American Mac Bohonnon.

''We got one day of training because our bags didn't arrive on time. It was all a bit of a shambles,'' he said. ''But it played out pretty well in the end.''
