Australia eased the pressure on coach Michael Cheika by beating South Africa 23-18 in the Rugby Championship.
Michael Hooper and Matt Toomua tries for the Wallabies came either side of Mbongeni Mbonambi and Makazole Mapimpi going over for the Springboks, who took an 18-17 half-time lead in Brisbane.
Two Toomua penalties won the match as the hosts held off late pressure.
Meanwhile, Nicolas Sanchez became Argentina's record points scorer in a 46-24 defeat by New Zealand.
Australia had gone into the game on the back of two defeats by New Zealand and six defeats from seven games.
Cheika's side were also without David Pocock and star full-back Israel Folau because of injury, while they also suffered a late withdrawal when lock Adam Coleman pulled out for family reasons.
However, helped by some lacklustre Springboks play, they managed to secure their first win in week three of this year's four-nation series.
