Malachi Rain Subecz was 5 years old when he was murdered by his caregiver, Michaela Barriball, who is now serving a life sentence with a minimum non-parole period of 17 years.

Coroner Janet Anderson has now made several recommendations including the development and implementation of an awareness campaign to encourage the identification and reporting of suspected child abuse. 

Safeguarding Children CEO Willow Duffy told Heather du Plessis-Allan, "I think a very well designed public health campaign would be excellent, but it cannot just be done on its own.

"It needs to be supported by many other factors that we know work to make a public health campaign successful."
