Jake Lehmann remains South Australia's last hope of victory against Queensland following another wicket-laden day at the Gabba on Tuesday.
Winless South Australia will go into day three at 7-94, still requiring another 80 runs for victory.
Lehmann is unbeaten on a match-high 41, with Nick Winter on three after SA's inexperienced top-order slipped to 5-32 in pursuit of 175 to win.
Incredibly, Lehmann and Winter also started the day at the crease, albeit batting in SA's first innings.
Mark Steketee did most of the damage for the home side taking 4-16.
SA's latest collapse capped another extraordinary day in which 20 wickets fell, outdoing the 17 wickets that fell on day one.
The number of wickets to fall outnumbered boundaries hit in the match until late on day two.
SA resumed at 7-67, but added just four to their overnight total to concede a 44-run first innings deficit.
But Queensland in reply lost wickets at regular intervals to be bowled out just before tea for a match-high 130.
There were failures for Queensland's experienced top-three with Matt Renshaw (11), Joe Burns (0) and Marnus Labuschagne (3) all dismissed cheaply.
Sam Heazlett top-scored with 37, while tail-end contributions from Mark Steketee (21) and Mitch Swepson (14) could prove the difference in the final wash-up.
SA seamer Joe Mennie returned figures of 3-16, while left-arm spinner Tom Andrews collected 3-42 to be a wicket shy of a first 10-wicket match haul.
