Coroner Simon McGregor is preparing to release his findings into the death of Indigenous woman Veronica Nelson.
The 37-year-old was found dead in her cell at the Dame Phyllis Frost Centre in January 2020 after making repeated calls for help.
She had been arrested three days earlier on suspicion of shoplifting and was denied bail.
Mr McGregor will find Ms Nelson's death was preventable and she was treated cruelly and inhumanely, The Age newspaper reported on Tuesday.
Among his recommendations, Mr McGregor will call on the Victorian government to reform the state's bail laws.
The laws were strengthened after James Gargasoulas drove into a busy Bourke Street Mall in January 2017, killing six people and injuring dozens of others.
Gargasoulas had been on bail at the time of the attack.
The Victorian government says it's considering how it can ensure the most vulnerable people in the community are protected.
"Fundamentally, our bail laws need to protect the community without having a disproportionate or unintended impact on those accused of low-level offending who do not present a risk to community safety," a government spokesman told AAP.
"We know that more needs to be done to address the over-representation of Aboriginal Victorians in the justice system."
The government will carefully consider any findings or recommendations from the coroner, the spokesman said.
