Ex-skipper Ricky Ponting has heaped the blame squarely on the Australian players instead of the selectors following another poor display in the second Test in Hobart.
The Proteas won by an innings and 80 runs after seeing Australia collapse with 8-32 on the morning of the fourth day to hand South Africa another dominant win.
It's the fifth Test loss in a row for Australia, after being on the wrong end of a 3-0 series defeat against Sri Lanka earlier on this year.
"The Aussie batters, they just didn’t know where to go, what to do," Ponting said on BT Sport.
"They got very defensive minded and when they do that – it’s been shown through this Test series – their techniques aren’t good enough to stand up.
"That’s a very, very poor batting performance again.
"Are they lacking confidence because of some of the selections and things that have happened? Maybe.
"But when you're out there in the heat of the battle, that's all gone. You've got to find a way to play the game.
"Everyone is talking about South Africa and how much of a together group they look. It's an interesting word. It's easy to look that way when you're playing the way they've played.
"It's easy to look dishevelled and unorganised when you're playing poorly.
"It comes down to the individual in that side, when you're confronted with a task for your team is you get out there and do it. It's as simple as that."
Ponting isn't unfamiliar with pressure surrounding the side having led Australia on 77 occasions, but the former captain believes the current team shows a lack of resilience.
"The great teams that I played in, we got ourselves in as much trouble as any other team," Ponting said.
"We'd be 2-0 or 2-10, but someone would go out there and say, 'Right, I've had enough of this. I'm going to change the way this game is going to get the job done for my team'."
