An evaluation of South Australia's safety watchdog will mark the first open hearing held by the state's Independent Commissioner Against Corruption.
The commissioner, Bruce Lander, said last month he had received a number of complaints and reports about SafeWork SA and had decided to conduct an evaluation of the workplace safety agency's regulatory arm.
Under existing law, ICAC investigation hearings into matters of maladministration are closed, but an evaluation may be heard by way of public inquiry.
"Carrying out such an evaluation in public allows both weaknesses and strengths of the agency to be highlighted and opportunities for improvement to be debated openly," Mr Lander said.
Legislation to allow public hearings into maladministration matters this week passed the state's lower house, after the Liberal government fulfilled a pledge to introduce the bill within its first 100 days in office.
Mr Lander had earlier announced he would focus on SafeWork SA after it dropped charges over the death of a young girl on a ride at the Royal Adelaide Show.
Health and safety charges had been laid against inspection company Safe is Safe over the death of eight-year-old Malaysian girl Adelene Leong, who was flung from the Airmaxx 360 ride in 2014.
