Only a disastrous final-day batting collapse will deny Queensland an eighth Sheffield Shield crown as the hosts all but batted Tasmania out of the reckoning at Allan Border Field.
While they only need a draw to claim the title, the Bulls pushed on at a respectable, if not breakneck, pace on day four as 10 batsmen scored between 27 and 77 to help them reach 516 and secure a narrow first-innings lead.
Tasmania reached 0-10 at stumps to reduce their deficit to 29, with the visitors needing a gargantuan last-day performance to snag an unlikely victory.
Openers Jordan Silk and Alex Doolan were the unbeaten pair at stumps.
Charlie Hemphrey (77), Jack Wildermuth (73) and Michael Neser (58) all reached milestones on Monday without pushing on to a standout century as Queensland recorded six first-innings partnerships greater than 50.
A 100-run partnership between Neser and rookie skipper Jimmy Peirson (48) came after the Bulls were six wickets down and still 115 runs in arrears and looks to be the final straw for the plucky Tasmanians.
The visitors will be rueing the 46 extras they conceded, including 15 no-balls, as four Tigers bowlers collected multiple wickets and off-spinning allrounder Beau Webster (3-83 from 25.3 overs) picked up three wickets on day four.
Resuming the day trailing by 244 runs, the Bulls erased close to half the deficit in the first session as Hemphrey and Wildermuth got stuck in on a surface that's shown few signs of deterioration.
After Sam Heazlett (43) added just seven to his overnight score before edging behind off Andrew Fekete (1-81 off 27), the English-born Hemphrey played anchor to his more daring partner.
Wildermuth used to be a barista at this venue's Picket Fence Café and he gave the Bulls a welcome shot of energy as he raced to a half-century off 59 balls by belting Fekete for back-to-back boundaries.
A hundred looked to be beckoning for Hemphrey before he too edged behind to Wade, with Jackson Bird (2-77 off 25) this time making the incision.
An entertaining duel between Simon Milenko and Wildermuth ensued after lunch when the Queenslander was knocked to his haunches by a rib-tickling short ball.
Wildermuth hit back with an exquisite cover drive for four before the Tigers quick took a tumbling return catch to end his innings on 73.
With Queensland six wickets down and more than a hundred runs behind, this was Tasmania's chance to strike.
But, perhaps in one positive sign for Australian cricket this week, collapses have been non-existent in this hard-fought clash. Twelve partnerships have extended past 50 in the match.
No.8 Neser duly sent his second and third balls to the boundary as he and Peirson pushed the Bulls towards parity either side of two brief rain delays.
After toiling fruitlessly in the muggy tropical heat through the early afternoon, Milenko and Webster combined to remove Peirson and Neser in consecutive overs before the tail-enders dug in.
Queensland's last three batters Mitchell Swepson, Brendon Doggett and Luke Feldman took the home side past Tasmania's first-innings tally of 477 with some lusty strikes.
But the Bulls batted until the shadows of the stands named after local legends Matthew Hayden and Stuart Law were long, leaving the Tigers with a tricky period to face out rather than a genuine opportunity to eat into the deficit.
Which they’ll attempt to do tomorrow before trying to find enough time to set a target and then capture 10 wickets.
