Australia took complete control of the deciding third Test against South Africa on an elongated third day in Cape Town.
Replying to Australia's 494 for seven declared, the Proteas were bowled out for 287 as Mitchell Johnson claimed 4-42 and Ryan Harris 3-63.
Australia closed on 27 without loss in their second innings for a lead of 234.
Following a rain-abridged second day, the tourists declared overnight - stranding South Africa spinner JP Duminy on a hat-trick - and made early inroads.
Home captain Graeme Smith edged behind when Harris angled one across him, continuing a dismal personal series.
Opening partner Alviro Petersen formed useful stands alongside Dean Elgar and Hashim Amla on his way to 53 but was third man out for 38 as James Pattinson and Johnson also benefitted from Brad Haddin’s safe hands.
Harris found some reverse-swing and the crucial breakthrough when he bowled Amla through the gate for 38, while Johnson also utilised late movement at pace in encouraging AB de Villiers to edge to Michal Clarke at second slip.
Duminy also fell cheaply, caught at the wicket off Harris, although Francois du Plessis and Vernon Philander dragged South Africa to 200 for six at tea.
Du Plessis negotiated a strong caught-behind shout, a missed stumping and a couple of other half-chances to clip Nathan Lyon wide of mid-on for four and bring up his half-century.
An airey drive at Johnson saw him caught by David Warner for 67, ending a 95-run alliance with Philander, who finished unbeaten on 37. Dale Steyn contributed breezy 28 but South Africa were asked to return to the field despite falling shy of their follow-on target.
Batting in the kind of situation he relishes, Warner raced to 25 from 17 balls during the six overs possible before the close.
