Australia is well recognized for its low population and population density (17529000 inhabitants and 2.3 inhabitants per square kilometer, respectively, in 1992; ABS 1994b). Australia also has an aging population, with population growth due not so much to domestic birth rates as to high immigration rates (ABS 1994b). Australia has one of the highest proportions of urban population in the world (85 per cent in 1990) and urban growth remains steady (UNEP 1991). As discussed above, Australia's urban structure is highly resource-intensive. Hahn (1991) offers some excellent ecological urban restructuring strategies which could be applied, with local variations, to help dematerialize Australia's urban structure.
