Cape Town - The Proteas have set Australia a target of 430 to win the third Test at Newlands as Cameron Bancroft's ball tampering on day three continues to be the major talking point.
The ICC confirmed on Sunday that captain Steve Smith had been banned for a Test for his role in the plans to implement the illegal action, while Bancroft himself has been given three demerit points and can play in the fourth Test at the Wanderers.
On the field, meanwhile, South Africa took more significant steps towards winning the Test and taking a 2-1 series lead into Johannesburg.
At tea on day four, Australia were 47/0 with Bancroft (22*) and David Warner (25*) at the wicket.
The visitors need another 383 runs for an unlikely victory.
The Newlands crowd, labelled "disgraceful" by Australian coach Darren Lehmann two days ago, were expected to 'boo' Bancroft and Warner when they walked out into the middle to start Australia's second innings.
Most, however, applauded.
Kagiso Rabada was fired up and looked to make early inroads, but the Australian openers got through to the end of the second session unscathed.
Before being dismissed for 373 in their second innings, the Proteas saw Vernon Philander (52*) get to his eighth Test fifty at No 8.
They were valuable runs for the hosts, who boasted four half-centuries on the scorecard.
From the beginning of the day, Australia looked flat.
AB de Villiers picked up where he left off on Saturday, scoring freely as Australia's bowlers went through the motions.
A De Villiers century looked almost certain, but out of nowhere Josh Hazlewood struck with a fantastic delivery that seemed to get big on South Africa's star batsman.
Shaun Marsh took the catch, and the Proteas were 269/6.
Quinton de Kock, meanwhile, was hurting Australia.
He went to his 13th Test 50 off just 67 balls and with every boundary the Aussies were sinking deeper.
De Kock (65) shared a 55-run stand with Vernon Philander before he was out caught behind by Paine having come down the wicket to Pat Cummins.
