Australian all-rounder Shane Watson, after his exploits on the field has associated himself with a Sydney-based charity.

The 27-year-old flambuoyant cricketer, who worked his way back into the Australian team, thanks to his all round brilliance for Rajasthan Royals in Indian Premier League, came up with the initiative after he was shocked to learn that Jaipur has 500,000 street children.

"I realised the kids over there don't have much of an opportunity. When some bombs went off in Jaipur it brought a lot of things close to home. I wanted to help the kids as much as I could, and I realised one way to do that was to support I-India," Watson was quoted as saying in the Sydney Morning Herald.

Watson said though he would be thrilled to see immediate changes, he is aware of the barriers the charity has to deal with.

"It won't happen immediately. I-India is doing a lot of good work. They might allow kids to shower twice a week, and while that might not seem much to some people I think it's better they get that chance rather than none at all.

"The children are also doing things such as jewelery courses, so they are at least getting skills to help them break out of the poverty cycle," he said.
