Captain Steve Smith and vice-skipper David Warner have been banned for a year by Cricket Australia over their recent ball-tampering in South Africa.
Cameron Bancroft, who carried out the cheating, was given a nine-month ban.
The three had already been sent home from Australia's tour - before a fourth Test begins on Friday - amid widespread condemnation stretching beyond sport.
Australia's prime minister Malcolm Turnbull had said the affair "bitterly disappointed the whole nation".
Smith, 28, and Bancroft, 25, have also been suspended from captaining Australia for at least the next two years.
Warner, 31, will not be considered for "any team leadership positions in the future", Cricket Australia said.
The body also said Bancroft used sandpaper to damage the ball during the third Test against South Africa.
It found Smith and Bancroft had made "misleading public comments" when on Saturday they instead claimed it had been yellow tape.
Cricket Australia had already concluded that coach Darren Lehmann was not involved in the controversy and he will remain in his post.
Smith, Warner and Bancroft are banned from international and Australian domestic cricket. They will also serve 100 hours of "voluntary service in community cricket" and can appeal against the suspension.
Cricket Australia said the players would be "permitted to play [Australian] club cricket and will be encouraged to do so".
They also remain eligible for competition outside of Australia, but earlier on Wednesday Smith and Warner were also banned from this season's Indian Premier League.
The body's chief executive James Sutherland said the three players were "sad, disappointed and remorseful".
He added: "This has caused damage to the game as a whole and certainly to Cricket Australia. It has compromised the fans' faith in cricket and it's our responsibility to reinstate that confidence.
