Malcolm's work is represented in corporate and private collections both in Australia and overseas and is available through a number of Melbourne and regional galleries. He undertakes regular workshops and demonstrations throughout Australia, and runs a school conducting classes in both watercolour and oil painting technique. He leads painting tours overseas, and, as a regular contributor to the Australian Artist Magazine and International Artist Magazine, his interest in recording his culture and heritage is well known.
A professional artist, Malcolm places great emphasis on the composition and content of a subject. Combined with sound draftsmanship and an understanding of tonal contrasts and colour, his paintings are both visually interesting and straightforward statements of everyday places and things around him. His paintings depict the life and activity of his environment. His watercolours and oils are characterized by a purity of colour and a straightforward arrangement of tonal values. This emphasizes the light, which, together with a broad approach to detail and careful composition make his paintings stand out from the crowd.
He has won numerous prizes and awards, and his first book, Simplifying Complex Scenes in Watercolour, was published in 2003 by International Artist.
