Cape Town - The Australian camp has dismissed ball-tampering claims against leg-spinner Adam Zampa.

Social media was abuzz on Sunday during Australia's Cricket World Cup match against India at The Oval when when cameras captured Zampa putting his hand in his pockets before bowling.

Australia, however, insist Zampa used hand warmers, as he has often been seen with during the Big Bash League.

"I haven't seen the photos, but I know that he has hand warmers in his pocket," Australia's captain Aaron Finch told Fox Sports.

"He has them every single game he plays. I honestly haven't seen them (the images), so I can't comment too much on it. But I know for a fact that he has hand warmers every game."

Zampa was not under any official investigation and umpires did not raise any concerns.

The Australian team was rocked by a ball-tampering scandal after a Test against South Africa in Cape Town last year which led to year-long bans for then-captain Steve Smith and opening batsman David Warner.

Fellow Test opener Cameron Bancroft was banned for nine months after admitting to using sandpaper to rub the ball.
