David Holmgren was born in the state of Western Australia. He studied at the College of Advanced Education in Hobart, Tasmania, where in 1974 he met Bill Mollison, who was then a lecturer at the University of Tasmania. The two found they shared a strong interest in the relationship between human and natural systems. Their wide-ranging conversations and gardening experiences encouraged Holmgren to write the manuscript that was to be published in 1978 as Permaculture One.
