Failing to alert victims about the release of their abusers from jail is putting lives at risk, a domestic violence advocate warns.
A state coroner recommended victims be given at least 48 hours' notice before violent partners are released from custody.
It follows an inquest into the 2020 death of Noeline Dalzell, who was fatally stabbed by her abusive ex-partner in front of their three children.
The proposal has drawn criticism from Victoria's police union, which says officers should be focused on responding to family violence incidents, not delivering release notifications from behind a desk.
Swinburne sexual violence expert Rachael Burgin said the recommendation reflected the bare minimum of police responsibility, saying "the most fundamental job of police is to protect and serve".
She said timely information was crucial for victims, so they can plan for their safety and access support from family violence services.
"We cannot continue to see women and children's safety be at risk because of challenges like resourcing," Dr Burgin told AAP.
"I would expect police in their role to protect and serve the community, would be taking this very seriously."
State Coroner John Cain in November found police missed opportunities to protect Ms Dalzell before she was murdered by James Fairhall.
Fairhall was released from custody three months earlier for breaching a family violence intervention order designed to protect Ms Dalzell. He is now serving a 25-year sentence for her murder.
Among 11 recommendations, Judge Cain echoed calls from the 2016 Royal Commission into Family Violence for an improved information-sharing system between agencies.
He also called on police to carry out an independent review of its family violence units, saying investigators' actions fell short of best practice.
Victims are only notified about their abusers' movements if they opt-in to an alert system through the Victorian Victims Register.
The Police Association of Victoria said notifications should sit solely with the Department of Justice and Community Safety.
"We don't have enough police to respond to victims of violence when they call us in the first place, let alone committing to further processes that would further diminish our emergency response and preventative abilities, by sending officers out in person to deliver these messages," the union told AAP on Thursday.
Victoria Police echoed those sentiments in a letter to the coroner.
"We believe it wouldn't be appropriate for Victoria Police to have sole responsibility for notifications in every family violence related case within the Victorian court system," the statement said.
The force's stance highlights systemic failure when addressing victim safety, opposition police spokesman David Southwick says.
"Victoria Police saying it doesn't have the resources to warn women when violent perpetrators get out of jail shows a failure in the system and a failure of government," Mr Southwick said.
A state government spokesperson said it was "completely unacceptable" women were still placed in danger after perpetrators were released from of custody.
