Queensland 82 for 1 trail South Australia 359 for 5 dec (Hunt 162, McSweeney 112*) by 277 runs

Hunt was finally dismissed trying to launch Mark Steketee into the grandstand to end a 212-run stand, South Australia then pushing the pace before declaring at the tea break.

Bryce Street started carefully before playing his shots while Joe Burns was cautious to ensure no further damage was done before bad light stopped play.

It was former Australian Under-19 talent McSweeney's second Shield century this season and third in 22 first-class games. He debuted for Queensland as a 19-year-old in 2018 before moving to South Australia ahead of the 2021-22 summer and has captained Australia A this year.

"Coming from Queensland, I haven't got [first-class] runs at the Gabba before," the 24-year-old said. "Nice to spend time in the middle with grandad here, and dad.

"The Gabba's ticked off now so hopefully more to come. There will be long days now [to make up for time lost to rain], there's still some time to catch up and if we bowl well tomorrow we'll get a good chance to win this game."
