The ICC did not boycott Cameron Bancroft, had supplanted Renshaw as Warner's opening accomplice in front of the primary Ashes Test in Brisbane.
Coach Darren Lehmann's future is also under intense scrutiny.
Renshaw, who has scored three centuries and is averaging more than 70 in Queensland's last six Shield matches, will jump on a plane to South Africa on Tuesday evening ahead of the final Test starting on Friday.
Renshaw was dropped at the beginning of the summer and Bancroft subsequently featured in the Ashes against England, which Australia won 4-0.
Australian cricket has been rocked by the ball-tampering scandal that overshadowed the heavy 322-run defeat in the third Test in South Africa.
Smith has been banned for one Test by the International Cricket Council for his role in a plot that saw team-mate Cameron Bancroft tamper with the ball by using yellow sticky tape during the third Test against South Africa in Newlands.
The announcement that he had been drafted into the Australian squad came before he went out to bat on Tuesday, and he capped his national recall with an unbeaten 81 from 83 deliveries in Queensland's nine-wicket win over Tasmania in the final. Ironically, Bancroft was chosen to replace Renshaw after the latter suffered a lean run of scores across Tests in India and Bangladesh before Australia's home season commenced.
That leaves the door open for Renshaw and possibly Joe Burns, George Bailey or Glenn Maxwell to be added to the team.
The sanction against the trio was announced by Cricket Australia chief executive James Sutherland, who had flown into Johannesburg just hours earlier to get to the bottom of the scandal, at a packed news conference.
