A life-size sculpted tree complete with parrots and a wandering dog won the National Aboriginal and Torres Strait Art Awards (NATSIAA). Every element has ceremonial significance, says Thu' and Apalech artist Keith Wikmunea, from Western Cape York.  Brenda L Croft's 19th Century-style photograph tells a multi-layered story of family bonds and forced child removal.
