Darren Lehmann said Australia's capitulation with the bat on day one of the second Test was unacceptable after South Africa humiliated the hosts in Hobart.
The outstanding Vernon Philander took 5-21 as Australia were bowled out for only 85 - their lowest in a home Test in 32 years - and the Proteas advanced to 171-5 in reply at stumps on Saturday.
Captain Steve Smith was unbeaten on 48 and debutant Joe Mennie (10) was the only other Australian to make double figures after South Africa had reduced them to 8-4 and 31-6.
Batting collapses have occurred all too frequently for Australia and head coach Lehmann said the worrying trend cannot continue.
"Conditions were perfect to bowl this morning, it was a tough toss to lose. But you've got to be better than that, you've got to refine your game a little bit," he said.
"We spoke about that before the game, holding your shape and making them bowl to you, but they did bowl some good balls to be fair.
"Yes it is hard. For us it's a case of getting these five wickets and batting big in the second innings."
He added: "We've got to be more resilient than that.
"The run out [of Callum Ferguson] doesn't help at this level, a couple of good balls, then the tail's got to stick in as well as all the batters. It's a whole effort from us, we just didn't play well enough today.
"[We feel] disappointment, more than anything, they're hurting obviously because you don't want to play like that, especially at home.
"To be bowled out for 85 is not good enough. We know that. It's about regrouping as best you can tomorrow and getting back into the game.
"I thought the wickets tonight were fantastic to keep us in the hunt and now it's a case of knocking the five over really quickly, but they're down as you would expect."
Temba Bavuma and Quinton de Kock will resume on 38 and 28 respectively on day two. Mitchell Starc (3-49) and Josh Hazlewood (2-36) gave Australia hope, but the Proteas lead by 86.
