Kathryn Heyman grew up in Lake Macquarie, New South Wales. After completing her Higher School Certificate she moved to Sydney to study arts and social work and subsequently shifted to Queensland, where she worked in theatre and attended the University of Southern Queensland's Drama School. She was a deckhand on a fishing boat in the Timor Sea, a writer and singer of radio jingles, and a waitress before becoming playwright-in-residence for the State Theatre of Western Australia, poet-in-residence for the 1992 Northern Territory Poetry Festival and writer-in-residence for the national Movement Theatre Forum of 1992.
Heyman adapted Paul Jennings's Unreal stories into a play which has had a number of Australian productions. Her play, That's the Way to Do It, for the Edinburgh Fringe Festival received a critic's nomination for the Festival Awards. She took her one-woman poetry play, Dancing on the Word, to the Edinburgh Fringe in 1993 and won the Hallam Poetry Prize the following year for the main poetry sequence in her collection, The Ideal Portrait Company. After moving to Scotland in 1995, Heyman has taught creative writing and drama at Sheffield Hallam University and enrolled in a Masters programme at that university.
Her first novel, The Breaking, was shortlisted for the Stakis Award for the Scottish Writer of the Year, and also listed for the Orange Prize. Heyman has received numerous awards and fellowships, including a Wingate Scholarship, an Arts Council of England Writer's Award, and several Scottish Arts Council Writing Fellowships. She was the Royal Literary Fund Fellow in Australia in 2003 and previously at Westminster Institute of Education, Oxford, for 2000-2001.
Heyman has published five novels since her debut novel appeared in 1997: Keep Your Hands on the Wheel, The Accomplice, Captain Starlight's Apprentice, Floodline, and Storm and Grace. The Accomplice was shortlisted for the Western Australian Premier's Awards, and Captain Starlight's Apprentice for the Kibble Literary Award. Heyman also publishes occasional short stories and less occasional prose pieces, including autobiographical essays and travel writing.
Heyman has conducted numerous creative writing workshops for indigenous Australian community groups in Western Australia, New South Wales and the Northern Territory, and has also formally mentored unpublished Indigenous writers.
