Queensland openers Matthew Renshaw and Joe Burns have each made superb fifties before Western Australia paceman Joel Paris hit back with three wickets before tea on day two of the Sheffield Shield clash at the Gabba.
The Bulls were 3-166 at tea after Renshaw (54 off 145 balls) and Burns (72 off 203) put on 116.
Left-armer Paris (3-21 off 17 overs) was the pick of the WA bowlers and deserved the rewards that finally came to him after lunch.
Burns tried to leave a Paris delivery that cut away late but brushed the face of his bat, with Josh Inglis snaffling the catch. Paris then snared Sam Truloff first ball.
The first day's play at the Gabba was washed out and Western Australia captain Sam Whiteman sent the Bulls in to bat after winning the toss.
Play started an hour early with 112 overs to be bowled on Friday in an effort to make up for Thursday's lost day.
Conditions were tough for batting early, with the pitch generating tennis-ball bounce and the ball seaming around.
Pacemen Paris, Matthew Kelly, Aaron Hardie and Lance Morris tested the Bulls openers with probing spells but Renshaw and Burns showed all of the experience and class that has earned them Test cricket honours with Australia.
Both left the ball with aplomb and put away the bad deliveries.
Renshaw has returned to the Bulls side after making 81 and 101no for the Prime Minister's XI against the West Indies.
The left-hander is making a strong case for a recall to the Australia side. He was caught at mid-wicket trying to up the ante but the manner of his innings showcased his calm temperament and grit.
Midway through the Shield competition, defending champions Western Australia have asserted themselves as the early favourites after winning four of their opening five games to be top of the table on 31.85 points.
Tasmania are second on 20.54 with the Bulls close behind on 20.42.
