If you want to talk about the best interests of the child, I think you need to work with the indigenous communities to help identify what that is in relation to who they are. Quite often the best interests of the child have been based on a system that wasn't our system. What might have been important in a European process might not be the most culturally relevant, important thing to these children.
Having healthy, happy children is what we all want ideally, but in what system we are assessing some of that really needs to be considered. I think that working with indigenous governments and our indigenous communities is going to be the best place to put that forward, so that it isn't a system that's just fluffy words and doesn't have any impact.
