The South Australian government is set to "face the music" over its "scandalous" failure to protect residents at Adelaide's Oakden Nursing home, Opposition Leader Steven Marshall says.
Independent Commissioner Against Corruption Bruce Lander has been investigating if any maladministration was involved in the running of the home which was shut down last year after the mistreatment and neglect of residents was revealed.
Mr Lander is due to release his report on Wednesday.
Mr Marshall has criticised the government for refusing to allow the commissioner to conduct public hearings during his investigation.
"Labor have done everything they can to keep their scandalous inaction to protect older citizens living with mental health problems from the public gaze," the opposition leader said on Tuesday.

"The Liberal Party tried to make sure that we could have open ICAC hearings when requested by the commissioner. Labor said no.
"They blocked it, they've got something to hide, tomorrow they'll have to face the music."
But Premier Jay Weatherill said he welcomed the release of the report.
"This is an important work of government and we're looking forward to the report, looking forward to responding to it and discussing it," he said
Earlier this month, Mr Lander said he would name three people who tried to keep their identities secret during the course of his inquiry.
It's not known if those individuals are current or former government ministers but they recently dropped a challenge to the commissioner's ruling that he could name them without their permission.
Mr Lander said concealing their identities would have made his report so vague it would "not be comprehensible".
The ICAC investigation followed failures in clinical governance at Oakden as well as incidents of rough handling of patients, excessive use of restraints and a high level of injuries.
