Jack McKinney was educated at Scotch College, Melbourne, Victoria. He served for four years with the A.I.F. and his novel, Crucible, draws on his experiences in France. Returning to Australia, McKinney worked variously as a jackeroo, boundary-rider, reporter, miner, drover and Queensland farmer. In the early stages of his literary career, McKinney wrote poems and short stories. Following an illness, he began contributing to philosophic journals and also wrote The Challenge of Reason (1950) and The Structure of Modern Thought (1971). Towards the end of his life McKinney began writing plays, many of which appear only in manuscript, including 'Change of Lodgings: A Comedy' [19..], 'Moment of Truth' [19..], 'No Man is an Island' [19..], 'No Pauper was I' [19..] and 'The Shadows We Cast' [19..]. A number of these are held by the Fryer Library, University of Queensland.
McKinney lived for many years at Tamborine Mountain with the poet, Judith Wright, whom he married in 1962. He is the father of Meredith McKinney.
