Nic Maddinson's bounce back has helped give Australia the chance to set up a fourth-innings chase for South Africa, with the tourists going to lunch on day four at 4-174 and with a lead of 280.
After his selection was heavily criticised following a first-innings 33-ball duck, Maddinson blazed his way to 48 on Monday as Australia went about chasing quick runs in the first Test in Durban.
He was bowled by an Anrich Nortje yorker just shy of a half-century, before Marnus Labuschagne (37), Steve Smith (27) and Matt Renshaw (32no) continued the charge.
