Sources differ as, according to the Australian Government's GeoScience website, Australia's land cover does change constantly due to weather and land use. Over a period of even one decade, figures will change.
An estimated 44% percent, or over one-third of Australia is made up of sandy or stony arid and semi-arid desert, while another 37% is sparse grassland or scrub. The figures for arid and semi-arid are very different from those given in the source quoted below.
Another source states the Arid and semi-arid zone constitute over 70% of Australia's land area (James, Landsberg & Morton, 1995)
