Beaten 17-47 in San Juan, after winning the first Test 41-26, Australia will face a Springbok team looking to regain momentum next week at Adelaide in their first Test of two in Australia. The second Test is in Sydney on September 3.
Hooker Folau Fainga'a, who had to sit out the second Test after a concussion suffered during training, believes he will be fit for consideration and is relishing the chance to go head-to-head against Springbok ace Malcolm Marx.
Fainga'a told rugby.com.au: "We've seen what they've done in South Africa.
"New Zealand came back strong, but we definitely know what they're capable of and will be preparing well for it.
"You get excited because you test yourself against the best in your position, and as a group, and myself, it's an exciting challenge ahead."
Fainga'a said a lack of experience hit the Australians in their loss. Playing without flanker Michael Hooper, five-eighths Quade Cooper and centre Samu Kerevi had been difficult.
"There was a bit of inexperience around the group, but the bright side of it is, the other guys got the chance to step up.
"They got the taste of Test level footy, for Nossy [Lachlan Loneran] and Billy [Pollard] to get a first start and cap (respectively) and for Pone (Fa'amausili) as well, we were tested in our depth and, unfortunately, we weren't good enough on that day," he said.
South Africa have struggled to win in Australia in recent years. Their last win was in 2013, and in seven subsequent Tests, their best result was a 23-23 draw in Perth in 2015. They also haven't beaten Australia in South Africa since 2019.
