Cage fights too violent for WA: Barnett

West Australian Premier Colin Barnett says his government will not revise its stance on cage fighting, despite the sport's capacity to generate millions of dollars for the state.

"I see it as a violent and aggressive sport," Mr Barnett told reporters on Tuesday.

"I'm not against boxing and I'm not against wrestling and so on, but I don't think we need to go down the path of cage fighting in Western Australia, and I think the vast majority of people would agree with me."
