Winter Olympic medal hopeful Jenny Owens has had a scare after a high-speed accident at the Australian National Ski Championships at the NSW ski resort of Thredbo.

Owens, a multiple World Cup medallist in the new Olympic discipline of ski cross, was leading after the first leg of the giant slalom on Monday but lost control at the second last gate in the second run.

The 31-year-old slammed her head, grazing her neck and bruising her hands and fingers. She will have a cognitive test on Tuesday to determine if there was any concussion but she was cleared of any broken bones.

"I just kind of got stuck on my tail in the softer snow and slipped and fell through the finish," she said.

"I'm banged and bruised and I hit my head really hard.

"But I'm a tough cookie and yet to break a bone touch wood, so hopefully it will only take a week or two to get over it."

Owens, an ex-racer who still competes in the alpine disciplines in Australia as part of her training schedule, hopes to be OK for the national ski cross event at Victoria's Mt Hotham in two weeks.

From there she will compete at the New Zealand Winter Games where a strong international field is expected to gather as a lead-up to February's Winter Olympics in Vancouver.

Ninth in the combined event at the 2002 Winter Olympics in Salt Lake City, Owens gave up the sport before taking up ski cross in 2005.

She picked up a second and fourth on the World Cup ski cross tour in 2008/09 and is considered an outside chance of a medal in Vancouver.
