Victoria's attorney-general is expected to be grilled at the state's first formal truth-telling inquiry.
Jaclyn Symes is set to give evidence on Friday at the Yoorrook Justice Commission, which is examining injustices in the criminal justice and child protection systems.
The inquiry has this week canvassed issues including Indigenous people's over-representation in the justice system, with Corrections Victoria Commissioner Larissa Strong on Wednesday revealing they account for 12.5 per cent of the state's prison population.
Commissioners have also decried deaths in custody and inadequate support for detainees.
The commission has been told of bail laws' adverse impacts on Indigenous people as the Victorian government works towards overhauling bail laws this year.
Ms Strong on Wednesday said the decision to build a now-idle $1.1 billion prison in Victoria was influenced by bail laws strengthened in 2018, which saw more people locked up on remand.
The inquiry has examined the government's work to raise the age of criminal responsibility to 12, and to decriminalise public drunkenness by Melbourne Cup Day.
Commissioners have also questioned the adequacy of police oversight processes.
Yoorrook is the first formal truth-telling inquiry into past and ongoing injustices against Indigenous people in Victoria, as part of the state's treaty process.
Police Minister Anthony Carbines and Victoria Police Chief Commissioner Shane Patton are expected to give evidence at the inquiry on Monday.
