Opener David Warner scored a run-a-ball century as Australia dominated the opening day of the third and deciding cricket test against South Africa, piling up 331 for three at Newlands in Cape Town.
The wicket was flat and the tourists took full advantage after winning the toss and electing to bat.
Warner's 135 punished a wilting South Africa attack that lost Dale Steyn after lunch when the world's top test bowler limped off complaining of pain in his right hamstring.
Captain Michael Clarke (92 not out) and Steve Smith (50 not out) put on 114 for the fourth wicket and will resume on the second morning as they seek to bat the home team out of the match.
The series is level at 1-1.
