South Africa ended their three-game losing streak in the Rugby Championship with an 18-10 victory over Australia.
Fly-half Morne Steyn, making his first Test start in two years, scored all the hosts’ points in Pretoria, kicking four penalties and two drop-goals.
Australia’s Scott Sio scored the only try as the Wallabies led 10-3, but they struggled to break down South Africa’s defence in the second half.
South Africa went above Australia into second place before the final round.
“Morne justified his inclusion,” South Africa coach Allister Coetzee said.
“He showed he is still a Test match player. He remains proud to play for the Springboks and that showed.
“I am a very happy man and will never underestimate any Test win. For a team that had their backs to the wall, a win like this means a lot and is a definite confidence booster.”
World champions New Zealand, who have already won the competition, play Argentina at 23:10 BST on Saturday.
