'Chinese bias': Aussies slam Olympic judges

Australia's Lydia Lassila and Jacqui Cooper have slammed the judges of their aerial skiing event at the Winter Olympics.

Lassila and Cooper, Australia's two medal chances in the discipline, accused the judges of favouring Chinese competitors and underscoring the Australians.

Both qualified for Wednesday's final, alongside fellow Australian Liz Gardner, but argued they should have featured higher in the rankings.

Lassila qualified ninth, Gardner 10th and Cooper 11th for the 12-woman final.

"There are random scores and that's not good enough," a furious Lassila told reporters after the qualifying.

"We've dedicated our whole lives to this. It's not good enough at an Olympics."

Lassila scored 85.65 for her first jump - a well-executed double twisting double somersault but expected far higher after receiving scores in the mid-90s for that jump in the past.

"I felt my jumps were really underscored," she said. "I was thinking 95, not 85. That's 10 points, which is a lot.

"I saw Xin Xin (Guo) from China do a full full full (a triple twisting triple somersault), and she crashed it and got 88.08 points. That doesn't make sense. I stomped a double full full and got 85.

"Even though her degree of difficulty is higher, she still crashed. That's something I don't understand."

Cooper, who is competing in her fifth Olympic Games, also suggested the Chinese athletes were favoured by the judges.

When asked whether she felt the triple jumps had been overscored, Cooper answered: "The triples in the red suits."

Cooper was unhappy with the score of 75 she received for her second jump, saying she had no choice but to go all out in the final to ensure she would not be underscored again.

"I was happy with my jump. It was well worth more than that and that's all that matters," she said.

"I just plan on wowing them, so there won't be any grey areas… you've just got to make sure you do them well enough that there is no question."
