Whole Australia team knew of sandpaper use - Khawaja
Usman Khawaja claims the entire Australia team knew about the use of sandpaper to tamper with the ball in the final Test of their 2018 series with South Africa.
Before Australia's recent Test series in South Africa - which the Proteas won 2-1 - Cummins said he had spoken to Khawaja about the publication of the book.
The 33-year-old said he has no concerns about potential sandpapergate revelations and felt it was "all dealt with then" and the team had "moved on".
"He didn't go into too much detail, just basically gave me the heads-up that he is doing a book and, as always, no worries," Cummins said on 8 October.
"Tell your story. It's fine. It's obviously a long time ago and all the investigations, everything was done back then and we answered every question a million times."
Khawaja also said he had consistently argued that the team should take responsibility together, including in the dressing room after the Cape Town Test.
He wrote: "I said: 'Take this as a team. We did this as a team. We knew what was going on, and we have to take it as a team'.
"Obviously, it didn't work that way, and those three guys got crucified."
The left-handed batter said he thought Smith, Warner and Bancroft "deserve" the "justice" of collective blame.
He added: "None of those three want to be the first to say anything. And rightly so, it will just be hearsay and 'their word' if they do. They needed someone else to say something.
"But I'm not doing this for any other reason than I think it's the right thing to do."
