He uses that artistic language - that combination of figuration, narrative and landscape - to describe Australia's shorter and sadder history of invasion and ecological destruction. From the bleak, denuded hillscapes of the 1990s, with their isolated markers of civilization - houses, gates, dining tables, curtains - to the more recent, richly-patterned treescapes of the Narawntapu National Park, Keeling's work uncovers and expresses the beautiful, tragic, surreal poetry of the Tasmanian environment.
