Australia's bowlers have struggled to push home their advantage in the second cricket test in Durban as South Africa reached 244 for 2 at stumps on the fourth day, chasing a world record target of 546 to win.
Phillip Hughes was finally dismissed for 160, his second century of match, before Australia declared at 5-331 in the morning session at the Kingsmead ground.
Trailing 1-0 in the three-match series, the South Africans weren't daunted by the task of batting out almost two full days.
They were boosted by an unbroken 164-run partnership for the third wicket between Jacques Kallis on 84 and AB De Villiers on 68.
