The South Australians are seeking to collect the state's first shield in 29 years and are also chasing a rare double - winning the shield and the one-day competition in the same season.
SA, who defeated Victoria in the 50-over final on March 1, have never achieved the double - Western Australia (five times), NSW (four times) and Victoria (twice) are the only states to complete the feat.
SA captain Nathan McSweeney opted to bowl, believing the pitch at Karen Rolton Oval on Adelaide's city fringe could offer some early assistance to pacemen.
"It's a great wicket but I think if our bowling attack can get anything out of it, it will be in the first hour and hopefully we can do some damage," McSweeney said.
SA made two changes from their side that downed the Queenslanders at the same venue last week, with Lloyd Pope and Henry Thornton dropped for returning paceman Brendan Doggett and allrounder Liam Scott.
"Ultimately with finals, hard decisions have to be made and hopefully the team we picked can do the job," McSweeney said.
The Queenslanders are without Matthew Renshaw, whose wife is awaiting the birth of their second child.
Test opener Usman Khawaja returns after missing the Bulls' last game due to a hamstring niggle.
Bulls captain Marnus Labuschagne said he would have batted if he won the toss.
"It's a nice wicket and if we can get through this morning's period, I think there's runs to be had," Labuschagne said.
