Tea Australia 390 and 314 for 6 dec (Renshaw 82, Maddinson 48, Maharaj 2-56, Nortje 2-56) lead South Africa 284 (Bedingham 49, Cummins 3-54, Hazlewood 2-54) by 420 runs

Matt Renshaw backed up his remarkable 190 in the first innings with 82 off 99 balls on a Kingsmead surface starting to play tricks. Having swiftly built a formidable lead, Australia declared by tea on day four with a beleaguered South Africa facing a daunting fourth-innings chase of 421 runs in the first Test.

Australia's second innings of 314 for 6 declared was scored at 5.41 runs an over with Pat Cummins smashing 32 not out off 12 balls, while Beau Webster finished unbeaten on 39.

It's been a potentially career-turning performance for No. 5 Renshaw, who had returned to Test cricket after three-and-a-half years as an opener against Bangladesh in August. No other batter in the match has reached a half-century so far.

Renshaw continued to reverse-sweep with good effect and appeared set to make it twin tons for the match until he was caught and bowled by spinner Keshav Maharaj, who juggled the catch low to the ground with third umpire Richard Illingworth adjudicating that he got his fingers under the ball.

Renshaw came to the crease after a solid platform had been laid by new opener Nic Maddinson, who set the tone in the morning session with an aggressive approach. Maddinson, a shock selection having not played first-class cricket since March 2025, made a breezy 38-ball 48 in a major relief after his excruciating 33-ball duck in the first innings.

Marnus Labuschagne looked in good touch at No. 3, but was dismissed for 37 off 58 for the second time in the match. It was a missed opportunity for Labuschagne, who entered the series under enormous pressure having not scored a Test century since the 2023 Ashes tour.

Australia needed to score quickly, with the distinct possibility of truncated play impacting their push for victory. Each of the first three days ended early in the final session due to bad light amid thickening dark clouds that gather like clockwork in Durban at this time of year.

After South Africa's batters wasted relatively benign conditions on day three, the surface is getting more challenging with variable bounce evident while spinners Maharaj and Simon Harmer produced significant turn.

Australia's quicks will have been closely monitoring counterpart Anrich Nortje, who had several deliveries die through to wicketkeeper Kyle Verreynne while he also produced vicious bouncers, including one that smashed into Steven Smith's helmet.

Australia resumed their second innings at 33 for 0 after just 5.4 overs were bowled before the familiar bane of bad light prematurely ended day three. Maddinson hoped to continue his momentum from the previous afternoon, where he avoided a pair with a first-ball boundary.

He did exactly that although rode some luck early with a couple of boundaries through the slips. Maddinson was in an attacking mood, a far cry from the first innings where he looked so tentative, pouncing on width to crack several blows through the off side to quickly overtake his highest Test score of 22.

He overshadowed Travis Head, who on 11 tamely fell to Marco Jansen when a leading edge flew to mid-on. Head let out a groan knowing his fate while his middling away record in Test cricket continued, where he averages 31.6 compared to almost 52 in Australia.

There will also be questions over whether he should switch positions with Renshaw and move back to No. 5, with Head having a highest score of only 29 in his last six innings. Skipper Temba Bavuma turned to Harmer early in the session, but Maddinson greeted him with a huge six down the ground as he moved to the brink of his half-century. However, he could do little against a superb yorker from Nortje that crashed into the stumps. Nortje could not sustain the pressure, with Smith shaking off the blow to his helmet by peeling off a trio of boundaries as the runs flowed.

Bavuma deployed Harmer and Maharaj, who were ineffective with just one wicket between them in Australia's first innings. Smith's eyes lit up as he danced down the pitch to smash Harmer down the ground to raise his half-century partnership with Labuschagne. But he could not repeat the dose moments later, holing out to the towering figure of Jansen who clung on at the second attempt.

Labuschagne appeared set for his first Test half-century since the Brisbane Ashes Test last December, but he trudged off the field in frustration after hitting Maharaj to cover. He finished with the exact same score (37) off the exact same balls (58) in both innings

After runs flowed in the first session, South Africa attempted to slow down the scoring but Renshaw could not be contained. He fittingly reached his half-century with a reverse-sweep to the boundary off Harmer, once again waving his bat to the sparse crowd.

With Jansen being surprisingly held back from the attack, Nortje shouldered the burden and was rewarded when he had Alex Carey chopping onto his stumps with a delivery that did not bounce as much as he expected.

Renshaw on 52 appeared to finally succumb to the reverse-sweep after being adjudged lbw to Harmer. But his immediate review was vindicated when replays showed the ball smacking the gloves before hitting the pads.

Renshaw's brilliant knock eventually ended, but South Africa's pain continued when Cummins threw the bat with great effect, including three sixes off an over from the hapless Harmer.
