Cricket Australia chairman David Boon has backed Test captain Pat Cummins and said his job is not under threat, as the fallout from Usman Khawaja’s autobiography continues to dominate Australian cricket.

“We absolutely support Pat,” Boon said in comments published by The Australian on Thursday, 12 November, describing Cummins as a player of integrity and making clear that Cricket Australia has full confidence in his leadership.

The row centres on claims in Khawaja’s book that he and all of his teammates on the 2018 tour of South Africa had prior knowledge of a plan to manipulate the ball — the episode that became known as Sandpapergate. The allegations have reopened old wounds, triggered calls for another investigation, and heaped fresh scrutiny on Cummins as the current leader of the Test team.

Khawaja has since cut short his book tour after a tense television interview, and has withdrawn from book interviews amid the controversy, while the Australian Cricketers’ Association has urged an end to online abuse directed at him.

Cricket Australia has already ruled out reopening the case. Chief executive Todd Greenberg said on Tuesday that there was no compelling reason for a new inquiry, and Boon reiterated that stance in his latest comments. The board’s position is that the matter was dealt with at the time and will not be revisited.

Cummins himself has yet to respond directly to Khawaja’s allegations, but he posted on X that he would be happy to speak to the media on Friday. White-ball captain Mitchell Marsh, who was in the Test team in 2018, was due to speak at a press conference in Perth later on Thursday ahead of a one-day international against England.

Khawaja’s claims have divided the 2018 touring party. Former teammate David Warner, who was banned along with Steve Smith and Cameron Bancroft for his part in the scandal, has backed Khawaja’s account to the hilt. Former Test bowler Chadd Sayers, who was also on the tour, has likewise supported the claims.

Others have pushed back. Fast bowler Mitchell Starc denied on Tuesday that he had prior knowledge of the ball-tampering plan, and several pundits have called on Cummins himself to address the allegations directly rather than leaving the response to administrators.

The timing could hardly be worse for Australian cricket. The team is preparing for a home summer headlined by the Ashes, and the captaincy question — whether Cummins can lead the side while his role in the 2018 affair is being publicly re-litigated — has become the dominant story of the build-up.

Boon’s intervention is designed to draw a line under that question. By stating publicly that Cummins’ job is safe, the chairman is signalling that the board will not allow a book-tour controversy to destabilise the Test leadership on the eve of the season.

Whether that settles the matter is another question. Khawaja’s book has already forced the sport to confront uncomfortable memories, and with Warner and Sayers backing his version of events, the debate over what the 2018 team knew — and when — is unlikely to fade quickly.

For now, though, the message from the top of Australian cricket is unambiguous: Pat Cummins stays, and the board stands behind him.
