South Africa built an intimidating lead of 294 runs by stumps of the third Test in Cape Town but much of the focus on day three was Cameron Bancroft and indications he may have been tampering with the ball.
Bancroft was captured on camera before Tea appearing to work the ball with a yellow object before hiding it in his trousers, and the incident attracted much of the discussion during the final session.
Meanwhile, an excellent 84 from opener Aiden Markram and a typically flawless 51 not out from AB de Villiers all but took the match out of Australia's reach, with the Proteas finishing the day on 5-238.
