Queensland 7 for 475 dec and 7 for 228 dec beat South Australia 258 and 317 (Weatherald 73, Carey 54, Cooper 52, Cutting 3-60, Floros 3-65, George 3-76) by 128 runs
Queensland secured victory late on the final day at the Gabba, where South Australia's last wicket fell with just 12 balls left in the day's play.
Theoretically chasing 446 for victory, the Redbacks' best hope was realistically a draw, and some fight from the tail gave them hope of doing so, until spinner Jason Floros sealed the Queensland win by bowled Chadd Sayers for 22.
South Australia had resumed on 2 for 71, and lost captain Travis Head for 34 and Jake Lehmann for 10. Opener Jake Weatherald compiled 73 before he was caught behind off Floros, but a pair of fifties from Tom Cooper and Alex Carey kept South Australia fighting. Cooper made 52 and Carey managed 54, continuing a fine game after he top scored with 76 in the first innings.
But Queensland's bowlers kept chipping away and got the result they were after, with Floros, Ben Cutting and Peter George each collecting three wickets.
