David Warner's manager alleges unnamed Cricket Australia (CA) officials gave players permission to tamper with the ball some 16 months before the 2018 Cape Town scandal.
The drama of Warner's leadership ban has continued after he pulled his application to have his sanction lifted due to frustration over the public nature of the review process.
In a 793-word statement posted on his Instagram page on Wednesday evening, Warner accused the independent panel undertaking the review of wanting to "conduct a public lynching".
In an interview on SEN on Thursday, Warner's manager, James Erskine, suggested players had been given approval to tamper with the ball after Australia was convincingly defeated by South Africa in Hobart in late 2016.
In the same Test, South African Faf du Plessis was later charged with applying saliva to the ball with a mint in his mouth, as Australia was bowled out for 85 in the first innings.
"Two senior executives were in the changing room in Hobart and basically were berating the team for losing against South Africa," Erskine said on SEN.
"Warner said: 'We've got to reverse-swing the ball. The only way we can reverse-swing the ball is by tampering with it'.
"And they were told to do it."
CA is yet to comment on the allegations.
Erskine said he felt Warner had been let down.
"There was far more than three people involved in this thing, they all got a caning and David Warner was completely villainised," Erskine said.
"He has shut up, he protected Cricket Australia, he protected his fellow players on my advice, because at the end of the day no-one wanted to hear any more of it and he's got on playing cricket.
"This is injustice at its greatest level."
Erskine's comments came as questions continued to be raised over how CA lost control of its own code-of-conduct changes.
Warner has been pushing since February to have his leadership ban reviewed, before CA initiated a change to its code of conduct two months ago.
That change was finalised last month, allowing Warner to lodge an application to have his lifetime ban reviewed.
CA confirmed it had supported Warner's request for the independent panel to hold the hearing behind closed doors.
However, both CA and Warner were told on Wednesday that would not be the case, with the panel of three independent code-of-conduct commissioners able to set their own parameters.
"We are disappointed with this outcome as our intention was to give David the opportunity to demonstrate why his lifetime leadership ban should be varied at an independent hearing and we amended our code of conduct accordingly," a CA spokesperson said.
"We supported David's wish for these discussions to be heard behind closed doors and respect his decision to withdraw his application."
Warner took to the field at Adelaide Oval on Thursday for the opening day of the pink-ball Test against West Indies.
He made 21 before being dismissed by West Indian pace bowler Alzarri Joseph.
