The Australian Cricketers' Association warned that the bans were disproportionate and inconsistent with the ICC's own ball-tampering sanctions, which had historically meant a one-Test ban or a fine. Cricket Australia held firm. CEO James Sutherland and head of integrity Iain Roy travelled to Cape Town, conducted interviews, and on 28 March announced 12-month bans for Smith and Warner, a 9-month ban for Bancroft, a two-year leadership ban for Smith, and a permanent leadership ban for Warner, who was identified as the originator of the plan and the only one of the three not to appeal.
Darren Lehmann, cleared by the investigation of any involvement, watched Smith's Sydney Airport press conference on television and announced his own resignation the following morning, effective at the close of the fourth Test in Johannesburg. Tim Paine, the wicketkeeper recalled to Test cricket only months earlier, was confirmed as captain. Justin Langer was appointed head coach. Sponsors moved quickly: Magellan Financial Group terminated its three-year naming-rights deal for the Test summer, Asics dropped Warner and Bancroft, and Sanitarium ended its endorsement of Smith.
Cricket Australia commissioned two reviews. The Ethics Centre's cultural review, led by Dr Simon Longstaff, was published in October 2018 as "A Matter of Balance." It described an organisation in which "winning without counting the costs" had become culturally embedded, and recommended sweeping changes to governance, selection, and player development. Chairman David Peever resigned within weeks of its release. The companion review by former Test players led to changes in how the side was led on the field, particularly around on-field behaviour and umpire interaction.
