He was born in Perth, Western Australia in 1929, and was educated at Perth Modern School and Wesley College, Perth, then the University of Western Australia from which he graduated with Bachelor’s (1951) Master’s (1955) and Doctoral (1960) degrees in agricultural science.
In 1951, he joined the Division of Land Research at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), becoming Associate Chief of that division in 1966. In 1967, he left the CSIRO and became a Professor of Biology at the Australian National University in Canberra. While at ANU, Slatyer travelled twice to the United States where he worked as a Visiting Professor at Duke University (1963–64) and the University of California (1973–74). In the United States, he was appointed a Senior Fellow of both the National Science Foundation and the Ford Foundation. In March 1975 he was elected a Fellow of the Royal Society
In 1977, Prime Minister Malcolm Fraser offered the position of Australia's Ambassador to UNESCO to Dr. Slatyer. Fraser had originally offered the post to Sir John Kerr, who as Governor-General had been responsible for the dismissal of Gough Whitlam's government in the 1975 Australian constitutional crisis, but considerable public pressure prompted Fraser to withdraw the offer to Kerr, and offer the post to Slatyer instead.
Slatyer returned to Australia in 1982, after four years in Paris, and resumed his professorship at ANU. Later that year, the Fraser government appointed him the chair of the Australian Science and Technology Council (ASTEC), a body set up in 1978 by Fraser as a government "think tank" on science and technology. In Slatyer's five years as chair, ASTEC was instrumental in lobbying for tax concessions for research and development in Australia, and conducting a review of the CSIRO. In 1989, Slatyer was made the first Chief Scientist of Australia, advising the Prime Minister of the day on matters relating to science and technology. He was also largely responsible during his tenure for the establishment of Cooperative Research Centres in Australia, a program designed to facilitate collaboration between business and researchers.
