The concept of "the bush" has become iconic in Australia. In reference to the landscape, "bush" refers to any sparsely-inhabited region, regardless of vegetation. "The bush" in this sense was something that was uniquely Australian and very different from the green European landscapes familiar to many new immigrants. The term "Outback" is also used, but usually in association with the more arid inland areas of Australia. "The Bush" also refers to any populated region outside of the major metropolitan areas, including mining and agricultural areas. Consequently, it is not unusual to have a mining town in the desert such as Port Hedland (Pop. 14,000) referred to as "the bush" within the media.
