Pat Cummins, the teenage fast bowler, followed up his six-wicket haul with the winning boundary as Australia secured a drawn series against South Africa by taking winning the second Test in a frantic finish in Johannesburg.
The 18 year old was a hero with the ball earlier in the match and on Monday came in with Australia wobbling on 292 for eight, still needing another 18 runs.
He rode his luck, offering Dale Steyn a caught and bowled chance, before pulling the match-deciding four off Imran Tahir.
Mitchell Johnson finished unbeaten on 40, while Brad Haddin's 55 and 39 from Mike Hussey had earlier helped nudge Australia towards their target of 310.
"Just to get a Test match is unbelievable. Obviously this is a great win today," Cummins, who was named man of the match, said at the presentation ceremony. "We came from behind and this just tops it off. It was great to bowl them out yesterday [on Sunday] and to contribute [with the bat] was even better."
Australia had been 142 for three overnight, but the morning session was washed out.
The Australians lost Michael Clarke, their captain, for just two and resistance from Ricky Ponting came to an end on 62 when he slashed a delivery from Morne Morkel to Jacques Rudolph at slip before Hussey, Haddin and Johnson led the fightback.
Michael Clarke, the Australia captain, said: "I couldn't be happier with the result."
And he said of Cummins: "He's a hell of a talent. It's not just opposition players, but the Aussie guys know how good he is.
"It is about now managing Cummins and making sure he becomes one of the all-time greats."
Graeme Smith, the South Africa captain, said: "We both threw a lot of punches and we've ended up level again. I must give credit to Australia today, to chase 310. A few of their guys stepped up and performed really well."
