Greg Warburton (1952–2022) trained at Hornsby Technical College and Alexander Mackie College in the 1970s. His work was hung in numerous group exhibitions from 1974, and in 1980 he received an Australia Council Grant to study in New York and Toronto. During the 1980s and 1990s he had four one-man shows, at the Holdsworth Galleries in Woollahra and the Mark Julian Gallery in Glebe. He was first an Archibald finalist in 1984, with a self-portrait; thirteen years later his portrait of multiple sclerosis sufferer Gennie Batterham was selected for exhibition. Since 2001 he has been an Archibald finalist four times, in 2008 with a portrait of Faith Bandler. He has been hung in the Salon des Refusés, Wynne, Sulman, Dobell and Blake prizes; he has won the Blake Viewer's Choice, and the Hunters Hill Portrait Prize twice; in 1996 he won the Bega Valley Art Award and the Walkom-Manning Art Prize. His work is represented in regional, municipal and private collections in Australia and overseas. Alongside his art practice, since 1992 Warburton has worked for organizations assisting people with disabilities.
