Most metropolitan centres and towns in Australia were constructed in the 19th to 21st centuries so they are modern and resemble North American rather than European settlements, although they do have their own influence.
The trend towards urbanisation is stronger in Australia than many other parts of the world due to much of the interior landscape in Australia being hot and arid. The result is not enough water to sustain a large population The fertile eastern seaboard and other coastal areas of Australia is suitable for large populations and hence where all the big cities are located.
Sydney is the most populous city in Australia and is built on what many describe as the most beautiful urban harbour in the world. Sydney's main landmarks, the Opera House and the Sydney Harbour Bridge are iconic of not just Sydney but of Australia too. Australia's second biggest city, Melbourne is the most European of all Australian cities with sizeable immigration from Italy and Greece, the city is the fashion and food capital of Australia as well as the arts capital. Brisbane comes in third. It is a river city that enjoys a sub-tropical climate Beautiful beaches can be found to the north and south of the city. Both Perth, and Adelaide have a mediterranean climate and populations between 1 and 2 million people. The Gold Coast is a coastal city situated very close to Brisbane. It is famous for it's beaches and coastal high-rise developments.
