Jordan Petaia has produced back-to-back clutch plays as Queensland Reds rallied from 12-0 down to beat the Brumbies 24-22 and secure hosting rights to the Super Rugby AU final.
The Reds' seventh-straight win this season and 10th consecutive at Suncorp Stadium came after a frantic five minutes of defence after they edged ahead for the first time in the 77th minute.
With his side trailing 22-13 with 18 minutes to play, Petaia, who scored the late winner when the sides last played, pinned his ears back and nailed a 50-22 kick.
He then out-jumped Tom Banks to win a James O'Connor bomb, finding the turf to make it a four-point game.
O'Connor then kicked another penalty before Fraser McReight and Angus Scott-Young won a crucial turnover in front of their posts as the Brumbies sniffed a match-sealer.
Another scrum penalty then gave O'Connor the chance to kick for the lead from a slight angle 35m out and he made no mistake.
They then twice forced turnovers as the Brumbies probed either side of the full-time siren in another classic encounter between the sides.
"Jordy sees it, delivers it and then the high ball take, just soared," Reds coach Brad Thorn said of Petaia's two big plays.
"It's funny I can feel myself sometimes moving, taking hit-ups, making tackles (in those final moments).
"But I just know with the guys they won't go away, they don't know how to do that and that's such a great quality.
"You think of (State of) Origin and those last minute, never-say-die efforts; I was really proud and the game was just good for rugby."
The Reds went in without in-form Wallabies centre Hunter Paisami (calf), teenager Josh Flook given the task in the centres as coach Brad Thorn kept Petaia on the wing.
Led by an aggressive Rob Valetini, the Brumbies had the better of the early exchanges but Flook defended stoutly and was rewarded with a second-half try down the blindside that came from another clever O'Connor kick.
Wright had the immediate reply though as the Brumbies edged closer to their first win in Brisbane since 2015 - one that would have kept their own hopes of hosting the decider alive.
The visitors were clinical early, Folau Fainga'a tip-toeing inside the right touch line to score from a rolling maul before Tom Banks ran 70m from an O'Connor intercept.
The hosts earned back some ground and O'Connor kicked two penalties to peg back the margin before it looked as if 100-gamer Bryce Hegarty had put them within a point.
He chased a Hamish Stewart grubber 50m, his tackle on Andy Muirhead knocking the ball clear before the fullback got a hand on it.
The try was denied on review though, officials curiously judging Hegarty had knocked the ball forward while making the tackle.
They had other moments too but penalties spoiled them, Nic White nailing a 53m penalty for 15-6 lead on the half-time buzzer.
Despite Brumbies captain Allan Alaalatoa's return, the Reds' scrum held firm though as they slowly pegged their way back.
Brumbies coach Dan McKellar was annoyed his team didn't land the killer blow but visibly frustrated by another lopsided 15-8 penalty count.
"There were some key moments there where they scrummed for penalty and got reward so it will be interesting to have a look at the maul, where we were dominant and if it should have been the same," he said.
"(We were) two times the more ill-disciplined side ... we talk about it every week (the penalty count with Rugby Australia's referees boss), but talk's cheap isn't it."
