The 23-year-old claimed he feels he has been "shafted" by judges when competing at recent events.

James was especially frustrated with the marks given to American Shaun White, expected to be his main rival for gold at the Winter Olympic Games here, at a World Cup event last week.

White scored a perfect 100 in Snowmass in Colorado and James said he had "question marks" over the scoring of the double Olympic champion’s run.

"I feel like there have been times I was a bit shafted," he said.

"At Snowmass I had question marks and had some words with the judges.

"Not because of getting second place - I am not a sore loser - I was just curious as to the 100.

"Personally, and I have spoken to a lot of other snowboarders, it's pretty tough to get a perfect score."

He added: "I didn't agree with that at all.

"Shaun, if he looked at that run, he would tell you that wasn't a perfect 100.

"The biggest things, the frustrating thing, was I have been working my whole life and then some silly people behind a desk dictate some scores."

James was the favourite to be named as his country’s flagbearer and the Australian Olympic Committee confirmed he had been chosen today.

The double world champion is bidding to become Australia’s first Olympic snowboarding champion.

He said he was "lost for words" when he was told he would be the flagbearer.

"I am absolutely overwhelmed and honoured to have been given the opportunity to carry the Australian flag," James said.

"Especially at this Olympic Games where I am accompanied by such an outstanding team full of amazing athletes it is extra special."
