Australia's gamble with a ring-in bowling attack paid off on day one of the third test, but South Africa's big guns had the final say as the Proteas rallied hard in their fight to protect their world No 1 ranking.
South Africa were bowled out for only 225 yesterday - and without another defiant knock from rookie batsman Faf du Plessis (78no) they might not have made it to 100.
But after the change of innings late in the piece, Dale Steyn (1-21) and Vernon Philander (1-8) immediately struck back in the 11 remaining overs to leave Australia 2-33 at stumps.
South Africa lead by 192 runs, and if the game's premier fast bowling attack continues to fire on day two, the match with seemingly everything on the line, is very much alive in Perth.
The WACA crowd thought retiring ex-captain and batting star Ricky Ponting was coming to the crease with 25 minutes left in the day, after Ed Cowan (0) and Shane Watson (10) continued the flimsy run of form from Australia's top three.
