The Springboks are sweating over the availability of hooker Adriaan Strauss who is the only injury concern at this stage.
South Africa are in Perth preparing for Saturday's Rugby Championship clash against Australia at Paterson's Stadium.
Team doctor Craig Roberts, during his usual Monday injury update, said Strauss's knee is the only major concern at this stage.
"From our side the only injury concern is Adriaan Strauss, who's got a mild knee ligament sprain," said Roberts.
"We will assess him later in the week and will make a call on his availability depending on how he goes through training in the next couple of days, but apart from that I'm happy to report we have a fit squad and are ready to go."
Should Strauss be ruled out, he will be the third hooker South Africa have lost to injury with Bismarck du Plessis and Chiliboy Ralepelle also out
"We have a few hookers on standby (in Tiaan Liebenberg and Craig Burden), but we have a very good medical team and I'm positive we'll get Adriaan through," said Bok coach Heyneke Meyer.
"We have travelled with three hookers, so should be fine for the first game."
