There is a paucity of published information about conceptions of Aboriginal child rearing and development among urban dwelling Nyoongar/Aboriginal people in Australia. We detail the unique findings from an Aboriginal early child development research project with a specific focus on the Nyoongar/Aboriginal community of Perth, Western Australia. This research significantly expands the understanding of a shared system of beliefs and values among Nyoongar people that differ in important ways from those of the broader Australian (Western) society. Consistent with the findings of research with other Aboriginal groups in Australia, and internationally, our work challenges assumptions underpinning a range of early childhood development policies and highlights the implications of cultural biases and misunderstandings among non-Aboriginal professionals in child and family services, education and other settings.
