"I've had a lot of people tweeting me about different things ... I've had hate tweets": Boardercross star Belle Brockhoff.

The father of controversial snowboarder Belle Brockhoff said he sold his Winter Olympics tickets in disgust because of what he believed to be a lack of support and recognition for his daughter.

Bruce Brockhoff emailed an open letter after his daughter finished eighth in the snowboard cross event in Sochi, outlining a raft of complaints against the Australian Olympic Committee and its national winter sports arm, the Olympic Winter Institute.

Amongst his issues were that he believed Belle did not have access to the same training facilities and physiotherapy services as other team members and that another snowboarder in the team received the benefits of Alex Chumpy Pullin's 'A' level scholarship at the OWI because he travelled with him.

He also outlined what he said were funding discrepancies in the team.

In a long and at times rambling letter, he was highly critical of a number of Australian officials and coaches.

"I am making this statement to explain why I sold my tickets to Sochi and cancelled my accommodation on a Norwegian cruise liner in protest over the lack of support and recognition for my daughter Belle," he said in the statement.

It was not immediately clear whether Belle supported his comments.

The AOC said it would respond in detail to the issues raised after the men's snowboard cross race on Monday afternoon in which Pullin, a two-time world champion, is favourite.

Belle Brockhoff is part of a group of Australian athletes in Sochi who had been using the sign off #teamoutcast on their social media accounts in the lead-up to the Games.

Brockhoff, fellow snowboard cross athlete Jarryd Hughes, halfpipe silver medallist Torah Bright and park and 'pipe rider Scotty James are part of the group.

They had questioned the funding and scholarship models used by the OWI but their claims have been rejected by it and the AOC.

The AOC said that Bright and James had both turned down scholarships while Hughes and Brockhoff receive funding commensurate with their results.

Brockhoff has one podium finish at a World Cup while Hughes won his first top level race in Canada in December last year.

Belle Brockhoff had already found herself in the spotlight at these Games, the openly lesbian athlete outspoken about Russian president Vladimir Putin's anti-gay laws.
