That is a question that took on new relevance on Sunday after Smith's two-year leadership ban ended.
Smith, David Warner and Cameron Bancroft were suspended from cricket after a ball-tampering scandal on the 2018 tour of South Africa.
A scheme was cooked up to use sandpaper to doctor the ball, with Smith being aware of the plan but doing nothing to prevent it going ahead.
Disgraced by the incident, Smith was served with a one-year playing ban that began on March 29, 2018, with a further 12-month suspension from leading Australia in any format of the game.
