“Mallyon also enjoys print surfaces characterised by loose painterly methods of plate rubbing. His prints and paintings feed off each other, but whatever the medium , these surface effects are an integral aspect of his subject matter -abstracted aerial topographies."
Sue Forster, Editor, Imprint Magazine Autumn 2014 volume 49 Number 2
"Greg’s work belongs to a significant global tradition of humans depicting the world from above for pragmatic, religious and aesthetic purposes – from Neolithic petroglyphs in Europe, to Indigenous depiction of Country, to Medieval maps, to the landscapes of modern Australian masters like John Olsen and Fred Williams. As Greg notes, mapping provides a “...very ancient perspective of the world.” His work enables a connection to the physical world while having an almost ethereal quality.
