THE IMAGE which Australia has presented to the world is that of a vast, empty, sunburnt country, with an oddly distinctive fauna and peopled with ruggedly independent pioneers who raise wheat and sheep, and combat drought, flood, and fire for survival. It is of a country which produces more than its share of athletes, tennis players, and swimmers in times of peace, and hard-fighting soldiers in wartime. Such an image is, of course, inadequate and distorted, and bears little relation to the true position at this stage of Australia's development. This is indeed a large country with a relatively small population, but only a small proportion of that population has first-hand experience of the rugged Australia of the &dquo;out-back,&dquo; the bush, and the rural life; the great majority live in urban communities in which parking space is a greater problem than drought, flood, and fire. With 83% of its population living in areas classified as &dquo;urban&dquo; for census purposes and a high proportion concentrated in very large cities, Australia is probably the most highly urbanised society in the world (see Davies and Encel, 1965: 296-297). There is a steady drift of population from rural areas: between the censuses of 1961 and 1966, urban population increased by 13.1% including an increase of 15.5% in the state and federal capital cities, while the rural population fell by 3.3% despite the national population increase of almost 10% (see Commonwealth Bureau of Census and Statistics, 1966).
