David Warner's half-century has helped steady proceedings for Australia, who closed day two of the second Test against South Africa on 112-4.
South African batsmen AB de Villiers and Jean-Paul Duminy dominated at the crease by reaching centuries, before they were dismissed on 116 and 123 respectively.
The Proteas reached tea on 413-8, but Australia managed to wrap up their opponents' innings when Nathan Lyon claimed the wicket of Duminy and Steve Smith dismissed Morne Morkel (1) in the evening session.
Australia came into bat, but the wickets began to tumble when opening batsman Chris Rogers fell for five runs from 12 balls when Vernon Philander claimed an lbw.
The tourists were shaken once again when Alex Doolan was sent packing for eight and Shaun Marsh shortly after followed for a duck from a Wayne Parnell delivery.
Warner managed to unleash an attack with the bat alongside captain Michael Clarke, but South Africa secured a crucial wicket when Philander's delivery led to Clarke's dismissal on 19.
Warner managed to reach a half-century and close the day on an unbeaten 65, while Lyon (12 not out) will also return to the crease for day three tomorrow.
