Wilam: A Birrarung Story is one day on a vital, flourishing river. As ngua rises, Bunjil soars over mountain ash, flying higher and higher as the wind warms. Below, Birrarung begins its long winding path down to palem warreen. Wilam – home. Yarra Riverkeeper Andrew Kelly joins award-winning picture book duo Aunty Joy Murphy and Lisa Kennedy to tell the Indigenous and geographical story of Melbourne's beautiful Yarra River, from its source to its mouth; from its pre-history to the present day.
