Western Australia will have a short canter to outright victory over Queensland at the Gabba, setting themselves a chase of just 68 after bowling the hosts out for 175 in the first session on the fourth day of their Sheffield Shield clash.
Leading by three at the resumption of play, Queensland made a solid start, before the Warriors got on a roll, taking the last six wickets for only 49 runs.
For Western Australia, outright victory will take them to 26 points on the Sheffield Shield table, just four points shy of leaders Queensland with two rounds remaining.
In a sad indictment of the Bulls performance, Joe Burns was top scorer with 43 and opener Ryan Broad the next best with 30.
Nathan Rimmington was once again instrumental against his former state, bettering his career-best first-innings figures of 3-63 with a second-innings haul of 3-28.
Michael Beer had the chance to show his guile, running through the tail to finish with flattering figures of 3-19.
Beginning their day's work at 4-111, Chris Hartley and Burns batted for almost 10 overs before the latter was beaten, playing around a straight one from Michael Hogan to be adjudged lbw.
Ben Cutting added 13 to the cause before chasing a wide delivery from Rimmington and driving on the up straight to cover, taking the Bulls to 6-151 - effectively 6-43.
Michael Neser, who was forced off the ground after spraining his ankle bowling on day three, came to the crease but he was having little chance to aggravate his injury with the wickets tumbling at the other end.
Chris Hartley was next to go, padding up to Beer and forced to trudge off disbelievingly when he was given out caught at bat-pad.
Cameron Boyce defended one ball from Beer before falling to the second, slashing outside off and appearing to feather through to Luke Ronchi behind the pegs.
Neser's gutsy effort came to an end on nine, leaving a pill from Rimmington that jagged back fiercely, clattering into off-stump with the batsman leaving. Luke Feldman could add just three before being trapped by a Beer quicker ball.
