Mr Coslovich says he had expressed concerns over Nikki’s safety to the Victorian Department of Human Services several times.
“The place just wasn’t the right place for her to grow up and develop,” Mr Coslovich told A Current Affair.
“I told that I heard he was a violent person and that he was staying in the house after he had said they weren’t living together. I told them.”
“Whether it was a lack of information, a lack of evidence, whether it was everybody — a lack of protocol or red tape or whatever it was, nothing was done and Nikki paid the price,” he added.
“She died alone, she had her daycare taken away, she had her dad taken away, she was locked in her room, spent a week of torment and died.”
Nikki’s case with the DHS was close just six weeks before her death.
The Victorian Department of Health and Human Services released a statement following the death of Nikki, saying it deeply affected the staff who worked on her case.
Nikki Francis-Coslovich's death is a tragedy and has had a significant impact on the community, including the child protection and agency staff who worked with her.
The department and leaders across the child protection system are committed to continuous improvement to ensure we are giving the best response possible for vulnerable children and their families.
Child protection decision making is complex and judgments are made based on the facts that are known at the time.
