Australia will not make any changes to the team chosen for the Perth Test against South Africa, irrespective of the result over the final two days at the WACA Ground.

The coach Darren Lehmann confirmed an unchanged squad for the Hobart Test, which starts from November 12, meaning guaranteed tenures for Mitchell Marsh, Peter Nevill and Adam Voges. Australia took a similar approach during the tour of Sri Lanka, making only the injury-enforced change of Jon Holland for Steve O'Keefe for the second Test before introducing more drastic changes in the third.

Lehmann reflected on how Australia had let the Perth Test get away, having made such a strong start on the first day and the second morning. He believed that the batsmen had not responded well to South Africa's loss of Dale Steyn to a shoulder injury, which he had seen as an opportunity to take command of the match.

"We spoke about that, probably not playing their natural games at times, especially to the left-arm spinner getting the field back," Lehmann told ABC Radio. "So we probably were a bit too timid at times and not looking to score and rotate the strike. Having said that they did bowl well, and we didn't counter it well enough.

"They do all the prep, they're great young men, they're trying to do as well as they can for Australia each and every time, it's just a case of little mental lapses at times. Collectively we're always pretty positive, but stats will show we haven't batted as well as we would have liked the last few Test matches. There's no hiding the fact we've got to bat better.

"There's always pressure when you're coaching your country or playing for the country, that's why the guys have got to where they've got to. They've been brilliant doing all the work behind the scenes and playing at the level below, now they've got to do it at this level. There's always pressure whether you win or lose, a lot less when you're winning."
