Queensland's police commissioner could be publicly grilled for a second time at an inquiry into domestic violence about cultural issues in the force.
The Commission of Inquiry into Queensland Police Service (QPS) responses to domestic violence was supposed to wrap up on August 18, but reopened after receiving unsolicited submissions from QPS members.
The inquiry has received more than 120 written and verbal submissions from serving QPS members about cultural issues after reopening last Monday.
The probe confirmed it has formal requests for additional material from the QPS on a range of topics before the submission deadline closes on Monday.
However, it did not confirm media reports that disciplinary files of the QPS senior executives had been requested.
"The Commission will not be commenting on the specifics of what has been requested of the QPS," an inquiry spokesperson told AAP.
"The Commission of Inquiry will make a decision on whether Police Commissioner Katarina Carroll or other witnesses are recalled once the closing date for submissions has passed."
Ms Carroll admitted the force had issues with sexism, misogyny and racism when she took the stand last month.
After steadfastly denying the QPS was plagued by cultural issues, she said she was appalled when the inquiry heard of vulgar public comments made by two senior police officers, including her deputy who later resigned.
The second officer remains on leave with his future in doubt as the service seeks legal advice.
Submissions on QPS culture must be made by September 5.
