Cricket Australia's integrity unit has contacted Cameron Bancroft to ask whether he has anything to add to his recent comments suggesting wider knowledge of the 2018 Newlands ball-tampering plot.

Ben Oliver, Cricket Australia's head of national teams, confirmed on Monday that the integrity unit, which is currently headed by Rebecca Murray, had reached out to Bancroft to see if he was willing to speak further about the affair that led to him being banned for nine months, while Steven Smith and David Warner were both suspended for a year.

"There was obviously a thorough investigation into that, to that incident," Oliver said. "There were actions taken on the back of that and then since that time, everyone who's been involved in the team has worked incredibly hard to rebuild confidence and to ultimately sort of aspire to make Australians proud of the Australian cricket team. So from that point of view that processes have taken place.

"I think we've maintained all the way through that if, if anyone had any new information relating to that incident that we've encouraged people to come forward and discuss that with our integrity unit. In this particular case, our integrity team have reached out to Cam again extending that invitation to him if he does have any, any new information. We'll wait to see his response on that, we haven't had had a response. But in saying that we're operating on different time zones."

Earlier on Monday, Michael Clarke had spoken plainly about the unresolved elements of the episode. "If you'd played the game of cricket, you would know more than three people know what was going on in there," Clarke told Sky Sports Radio. "The problem Cricket Australia has is the fact they've tried to sweep it under the carpet and not come out and tell the full story.

"They go and do that Netflix or whatever it was [Amazon] and show all that, come inside the change room and let's talk about what happened after Sandpapergate, but the public want to go 'hang on a second, take me through the few months before Sandpapergate, what led up to that, what happened in South Africa, there's a TV show for you Netflix, give us that information. It will continue because it hasn't been finished, so much is left unsaid from the players and even what happened with staff.

"They [CA] did not want to go any deeper than that superficial example of ball-tampering. They did not investigate to see whether it was systemic had it been going on and on and on. Around the cricketing globe it was widely accepted a lot of teams were doing it."

"You don't have to have played cricket at the highest level. If you know anything about the game of cricket, you know on that day, on that field, what went down, more than three people had to know about it. Impossible not to... that's why there's going to be finger-pointing until, I think until someone writes their book and tells the complete, honest truth. I don't think Cameron Bancroft should be smashed for what he's come out and said, he's tried to say nothing but he's doing an interview."

Adam Gilchrist had also stated that he felt the issue was not resolved properly because it had not been fully investigated, particularly in terms of global "ball management" in the period leading up to Newlands.

"There was an opportunity for CA if they were going to make such a strong statement they needed to do a more thorough investigation to work out where the root of the problem was," Gilchrist said on SEN Radio. "Anyone would be naïve to think people were not aware with what was going on about ball maintenance. I don't think Cricket Australia wanted to go there. They did not want to go any deeper than that superficial example of ball-tampering.

"They did not investigate to see whether it was systemic had it been going on and on and on. Around the cricketing globe it was widely accepted a lot of teams were doing it. You haven't seen any reverse swing since that incident as a general statement across world cricket. Very minimal reverse swing. The positive that has come out with that punishment is it seems to have been eradicated from the game because it was getting out of control around the entire cricket world, not just the Australian cricket team."
