Just nine days after losing 10 wickets for a total of 86 runs to be bowled out for 244 on day two of the first Test in Perth, Australia lost 10 for 85 on the opening day in Hobart.
Although this time, that was all they scored.
South Africa ripped through the Australian top order in devastating fashion early to see the hosts on 5/17 at one stage, before they limped their way through to 85 after being dismissed in just 32.5 overs.
The Proteas weren't without their struggles with the bat either, but there's no doubt they're in the box seat after finishing the day on 5/171.
Faf du Plessis sent Australia in to bat after winning the toss, and the captain looked like a genius as David Warner (1) and Joe Burns (1) both fell in the first two overs.
The wicket was extremely kind to bowlers, as Vernon Philander and Kyle Abbott had the Aussie batsman under extreme pressure with almost every ball they faced.
Philander in particular was working wonders with the ball, as he got Usman Khawaja and Adam Voges to bite and edge the ball on consecutive deliveries, as Australia were languishing on 4/8 with Philander on a hat-trick.
Callum Ferguson, one of two debutants in the Australian team for the Hobart Test, had to face the hat-trick ball, but managed to avoid another dismissal, although only just.
Australia's biggest threat with the ball would soon leave the field, as a collision between Philander and Steve Smith saw the paceman come off second-best and leave the field of play with a shoulder complaint.
Philander would return after lunch and take two more wickets as he finished with an impressive 5-21.
Ferguson didn't last too long at the crease either, as slow running between the wickets cost him dearly after a direct hit from Philander's substitute fielder Dane Vilas.
Australia moved to 6/31 after Peter Nevill was caught out front by Kagiso Rabada, before Smith and debutant Joe Mennie put on Australia's biggest partnership of the opening innings.
Mennie fell for 10 as Australia's tail end could only add 24 runs to the total, as Australia were bowled for their lowest score on home soil in 32 years, 85.
Steve Smith shouldered the load for the host with an unbeaten 48*, as the captain was the only real threat to the Proteas' bowling line-up.
The visitors came in soon after and started strongly before tea, with Dean Elgar and Stephen Cook heading into the final session at 0/43.
As soon as they resumed Mitchell Starc had South Africa on the back foot, as the first delivery after tea trapped Elgar and the opener was dismissed for 17.
Starc's final ball of the same over saw Cook send an edge through to Nevill behind the stumps, and the Australian line-up had some belief.
JP Duminy only lasted four balls as Starc struck again to move the Proteas to 3/46, and South Africa were hoping they weren't going to outdo their opponents with the bat.
Hashim Amla put on a strong 47 to steady the South African ship, as he helped his side calm the nerves and get back on top of the Australian bowlers.
Temba Bavuma and Quentin de Kock combined for 39 to finish off the opening day, as South Africa will resume day two on 5/171 with the Bavuma and de Kock on 38* and 28* respectively.
