Steve Smith has suffered a rare failure at the Gabba in his Sheffield Shield return, the star batsman dismissed for a duck after New South Wales had rolled Queensland for 153 on day one.
Smith slashed loosely at a Cameron Gannon delivery, with Joe Burns pouching the catch at slip as Test teammate David Warner watched on from the other end.
'MY BODY SHUT DOWN': Steve Smith reveals horror fallout from Ashes heroics
It was a rare failure after Smith's dominant Ashes series, in which he amassed 774 runs at an average of 110.57 against the hapless English.
It left the Blues on 2-14, which soon became 3-14 when Gannon took his third scalp with about an hour to play on a day dominated by the bowlers, namely Harry Conway who ran through the Bulls' tail to finish with 5-17 from 13 overs.
Warner is also playing his first Sheffield Shield innings since a ball-tampering ban and will be keen for runs after his Ashes tour reaped just 95 at 9.5.
Earlier Test No.3 Marnus Labuschagne saved the Bulls' blushes with a patient 69, but when he became Conway's second wicket the floodgates opened following a day of extreme pressure from the Blues' attack.
Sean Abbott (3-25 off 18) and Trent Copeland (1-48 off 18) were also impressive for the visitors.
Test aspirants Joe Burns (13), Usman Khawaja (1) and Matthew Renshaw (19) all missed chances to press their case, while Mitchell Starc (0-42 from 17) produced terrific carry on a relatively tame Gabba wicket but failed to take a wicket.
Renshaw looked solid in an 88-ball innings before edging Copeland and departing to a sharp catch from a diving Steve Smith at second slip.
Khawaja, coming off consecutive one-day hundreds for his state, threw his head back when trapped lbw by Conway midway through the first session on Thursday.
Burns suffered the same fate, missing a full ball after he and Renshaw had survived a long period of sustained pressure.
Labuschagne was patient throughout and had just started to score freely when trapped by a ball that may have been creeping down the leg-side.
