Book excerpt: This book highlights key principles emerging from the process of implementing an entire community and government approach to supporting families at risk of vulnerability. Drawing on the expertise of a number of practitioners and researchers, it also examines the efficacy of some of the early intervention and prevention strategies developed through the Australian Communities for Children initiative. It will be of particular interest to community services, education and child welfare practitioners and policy makers involved with, or contemplating involvement in, implementing a place-based collective impact approach to child development, wellbeing and protection. How can we better engage with families at risk in a digital world? How can we deliver holistic, integrated support? How can we redesign our family support systems? What kind of leadership and governance will it take to implement the kind of systems change that delivers improved outcomes? These are critical questions we need to engage with if we are to collaboratively redesign inadequate, siloed approaches and build family-friendly communities that improve the lives of children and families.
