Rabada produced match figures of 11/150 - the fifth time he has taken a 10-wicket haul in a game - to help set up the win for the Proteas to level the series 1-1 with two Tests to go.
The Proteas are yet to reveal whether they will appeal the code-of-conduct charge resulting from Rabada's physical contact with Steve Smith on day one of the second Test.
And Mitchell Marsh was guilty of the same offence after swearing at Rabada once he dismissed him on day four.
Rabada received a further 15 percent deduction of his match fee and an additional demerit point.
"We're just going too (far) on the sensitive side with everything", he said. "I can't keep doing this because I am letting the team down and I am letting myself down", Rabada told reporters on Monday.
"I just said I would like the same to apply to KG".
"It's bittersweet. I would've loved to have been playing the next game". The 22-year-old took 10 or more wickets in a Test for the fourth time in the process.
He had the opportunity to avoid the contact, and I could not see any evidence to support the argument that the contact was accidental.
Crowe detailed in a statement how disappointing it was that Rabada's send-off came one day after the match referee met with both captains. Right now, he is he is accumulating demerit points nearly as quickly as wickets. While Steyn would have been a welcome addition to the squad in Rabada's absence, his availability hinged on whether he was able to play for the Titans in their Sunfoil Series fixture that starts on Thursday. It has 48 hours to decide on a possible appeal, the team said, although captain Faf du Plessis admitted he was not confident an appeal would be successful. "I don't think there is a big turnover when it comes to (challenging) these things".
For de Villiers, it was the first Test hundred since January 2015 and the fifth time he passed 50 since he returned to Test cricket in December a year ago.
After almost two full Test matches Australia's bowlers finally found a way to get out AB de Villiers, but from the moment Mitchell Marsh dropped a sitter from Aiden Markram off the bowling of Josh Hazlewood, it was clear the visitors were never a hope of defending the slender target they had set South Africa to win. "To be honest, I just let it out", he added. My question was: why are both these incidents labeled the same?
A dramatic Test series is unfolding in South Africa, the script assembled somewhere in pace-bowlers' heaven. For us it's about proving that what KG did. they call it body contact, we would say it is a shirt being brushed or it was not deliberate.
"He [Rabada] has to show that passion, otherwise you can just put a bowling machine [on] and [make a] robot bat".
