A Nathan McSweeney century against his former Queensland Sheffield Shield teammates allowed South Australia to declare at tea on day two and chase a result in their rain-hit Gabba clash.
Wet weather again stole time away from both sides early on Tuesday before Redbacks batsmen Henry Hunt (162) and McSweeney (112 not out) continued what they had started a day earlier.
Hunt was finally dismissed trying to launch Mark Steketee into the grandstand to end a 212-run stand, the Redbacks then pushing the pace before declaring at 5-359 at the tea break.
The Bulls reached stumps at 1-82, 277 runs behind. Matt Renshaw's (26) was the only wicket to fall, the left-hander's breezy knock ending when he clipped a ball off his pads to a juggling Jake Fraser-McGurk at square leg.
Bryce Street (47 not out) started carefully before playing his shots while Joe Burns (five off 49) was cautious to ensure no further damage was done before bad light stopped play.
It was former Australian U19 talent McSweeney's second Shield century this season and third in 22 first-class games.
He debuted for the Bulls as a 19-year-old in 2018 before moving to South Australia ahead of the 2021-22 summer.
"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."
