Queensland collapsed in a heap to lose 6-9 as South Australia paceman Nathan McAndrew breathed life into the defending champions' season in a stunning seven-wicket win.
McAndrew's 5-32 in the second innings at the Gabba on the third morning of the Sheffield Shield clash was the decisive spell that now has South Australia breathing down second-placed Queensland's neck.
The Bulls started the day at 4-110, a lead of 81, aiming to set a 200-plus total for the visitors to chase. They got nowhere near it, bowled out for 119 as the last six wickets fell in just 12 overs.
The visitors polished off the runs with ease with Henry Hunt (29) the top-scorer.
The rot started for Queensland in the third over of the day when paceman Liam Scott trapped Hugh Weibgen (34) in front.
McAndrew, who destroyed Queensland in last summer's Shield final, found his groove immediately and had Michael Neser (one) nicking off.
In his following over a brute of a McAndrew bouncer accounted for Hayden Kerr, caught in the slips, and with his next delivery Mitch Swepson holed out at mid-wicket. Neither batter troubled the scorers.
Jordan Buckingham polished off the last of the recognised batters in Jimmy Peirson for 11, and tailender Tom Straker for a duck and the demolition was complete.
