The word ‘Yerrakartarta’ is a Kaurna word meaning 'at random' or 'without design'. This work reflects the seemingly random order of the natural world and consists of various sculptural elements set within the pavement and surrounding walls. The work incorporates fossil-like animal forms, representing the history of the land and includes a large ceramic mural about the Tjillbruke Dreaming story.
