Australia were forced to follow on for only the third time in the past 38 years after being dismissed for 99 by South Africa on day four of the second Test in Gqeberha.
Left-armer Marco Jansen took a superb 5-33, while Kagiso Rabada and Wiaan Mulder claimed two wickets each as the Proteas roared back into the match and gave themselves a real shot at levelling the series. South Africa were 110-6 early on day three, their hopes severely dented, but they scrapped their way to 425-9 declared after Temba Bavuma's 179 and Jansen's 85. That gave them a 326-run first-innings lead.
Australia's collapse was stark. After opener Nic Maddinson was dismissed late on day three, South Africa took the remaining nine wickets inside 40 overs on the fourth day. Steve Smith was the tourists' highest scorer with 28. No other batter passed 14, and the highest partnership was just 23.
The last time Australia were forced to follow on was against India at Sydney in 2019. Before that, the most recent occasion was the fourth Ashes Test at Trent Bridge in 2005. It was also their biggest first-innings deficit since a Test against the West Indies in November 1984, with Australia now trailing by 422 runs.
