Shane Warne took six wickets and Australia defeated South Africa by 112 runs to take an unbeatable 2-0 lead in their three-match Test series on Tuesday.
Warne, who took 6-86, finished off the South African innings in deepening darkness, as stand-in captain Adam Gilchrist had to withdraw the fast bowlers from the attack to push for the win.
Regular captain Ricky Ponting missed the day's play with food poisoning.
"South Africa showed a lot of fight out there, and in the end we probably wanted it just a little more," Warne said.
Warne dismissed tailenders Andre Nel for a stubborn 14 and Makhaya Ntini for a duck, after the Australian legspinner started the day by taking the wickets of South Africa's top three batsmen.
He added the important wicket of Jacques Rudolph in the afternoon session, getting a ball to loop up off the batsman's pad and onto his gloves for Justin Langer to take an easy catch and dismiss the South African for 36.
"Warne was superb today," said South Africa captain Graeme Smith. "He won the game for them today."
Australia set South Africa 410 to win after declaring its second innings at 307 for four before tea on the fourth day.
