Guy is an award-winning painter, writer, curator, filmmaker and teacher. He trained in England at St Martins School of Art and the London College of Printing, moving to Australia in 1981. He worked in advertising as an art director and writer before returning to oil painting in 2003.

In 2010, he completed the Master of Studio Arts (Painting) course at Sydney College of the Arts, the arts faculty of the University of Sydney, where he also served on the Academic Board.

Best known for portraiture, works from Guy’s major series ‘After Retinal Detachment’ – exploring the effects of an eye injury in late 2011 – were hung in the Archibald Prize in 2015 and 2013 and the Salon des Refusés in 2017.

Other works were hung in the Mosman Art Prize (five times), the inaugural Arts Access Australia Art Award, the biennial Percival Portrait Prize in Townsville, Qld (five times) and twice in the Black Swan Portrait Prize (now the Lester Prize) in Perth, WA. Ten works made the semi-finals of the Moran Art Prize over eight years with one being a finalist in 2015. He was also selected for the Fisher’s Ghost Contemporary Art Award (twice) and a portrait of Astronomer Professor Fred Watson, AM was selected in the Open Section at Campbelltown Art Centre.

In 2017 Guy joined the Board of Arts Access Australia, the peak body representing disability in the arts.

He now teaches painting for the City of Sydney as part of the Pine Street Creative Tutor Panel at Ultimo Community Centre .
