Reports in the Australian media, external said the former Australia batter had pulled out of several engagements following an interview with broadcaster ABC in which he refused to name which national team players knew of ball tampering in the 2018 Test series with South Africa.

Khawaja insisted in the interview that he wanted his former team-mates to take collective responsibility as a team, but did not want to be responsible for a "witch hunt" regarding specific players.

"The book tour is 100% still going ahead, we've just had to make some adjustments this week, but no major cancellation of the tour at all," said Khawaja's publisher Penguin in a statement to ABC.

The fall-out from the series led to bans for captain Steve Smith, vice-captain David Warner and fellow batter Cameron Bancroft, but a Cricket Australia investigation found the national side's bowling attack were unaware of the ball-tampering.

Australia's attack in the contentious third Test - Pat Cummins, Josh Hazlewood, Nathan Lyon and Mitchell Starc - remain fixtures in the national side.

The quartet issued a joint statement in 2021 saying they "did not know a foreign substance was taken on to the field".
