Desert Lake is a book combining artistic, scientific and Indigenous views of a striking region of north-western Australia. Paruku is the place that white people call Lake Gregory. It is Walmajarri land, and its people live on their Country in the communities of Mulan and Billiluna. This is a story of water. When Sturt Creek flows from the north, it creates a massive inland Lake among the sandy deserts. Not only is Paruku of national significance for waterbirds, but it is has also helped uncover the past climatic and human history of Australia.
