Jade hadn't even celebrated her 14th birthday when she died from a drug overdose.
The sad story of the Victorian teenager, who lived with an intellectual disability and was a victim of abuse and chronic neglect throughout her short life, is just one example used to highlight shortfalls in the state's child protection and care system.
The Commission for Children and Young People's annual report, released on Thursday, called for the reform of systems to prevent the state's most vulnerable children from harm or death.
Jade had been subject to nine reports by authorities.
"We found that child protection (services) did not adequately assess the risk to her associated with living in a family where she was exposed to ongoing family violence and neglect," the report reads.
There was also "an inadequate response to Jade's increasingly sexualised behaviour," the commission noted.
The deaths of youngsters known to child protection services has highlighted the heightened risks for children with complex medical needs, or disability.
"The service system generally did not intervene in a meaningful way to better support them or their families or provide them with protection," the report said.
Multiple inquiries over the past year revealed "the consequences of a child protection system under immense and ongoing pressure".
More than 25 child suicide deaths between 2007 to 2015 were examined in one of the inquiries, revealing "missed opportunities".
While there has been increased investment and some systematic change, Principal Commissioner Liana Buchanan said more sustained investment was needed.
"We examined a sample of child deaths involving cumulative harm and suicide, revealing children's devastating and sustained exposure to neglect and abuse without meaningful intervention," she wrote.
Another inquiry into 72 deaths of vulnerable children and young people with complex medical needs and/or disability, found child protection services had not considered all risks to these children or their parents' capacity to care for them.
The commission also found these children faced a "much higher risk of abuse, neglect, of not being heard and not getting the support from services they need to live the best life they can".
More than 45 per cent of the 850 notifications in 2017/18 related to physical violence, the report said, adding there is a lack of coordination between child protection, family services and disability services which need to be addressed to prevent the situation worsening.
