As many as 400 Aboriginal children and babies are likely to have been buried in unmarked graves at three former Western Australian missions, the vast majority of them interred after dying when five or under, a Guardian Australia investigation can reveal.
Spanning decades, more than 740 First Nations people, the majority of them very young, were most likely buried with no record at just three church and government-run missions in the state: Moore River, Carrolup and New Norcia.
