Moira McKinnon graduated in medicine from the University of Western Australia and travelled widely as a specialist in population health and infectious diseases. Her particular interests are emerging infectious diseases and the relationship with global and environmental health. She sees the connection between indigenous societies and global health as poorly understood and possibly containing a knowledge or a ‘knowing’ that is essential to the health of the earth and mankind. Her upcoming book, Cicada, a fictional account of survival in the Australian outback, is a fast paced story of the hunter and the hunted and yet its basis is to explore the relationship of humankind to nature. Her essay ‘Who Killed Matilda?’ published by the Australian Book Review (July 2011) was written during the research for Cicada and also examines the themes of nature, belief and survival.
