Australia is a vast country, covering an area of nearly three million square miles. Due to the extremely dry climate of most of the interior of the country, the large majority of the 22 million or so Australians live in and around the major cities of Sydney, Melbourne, Brisbane, Perth and Adelaide. All of these cities are located on or near the east, south or west coasts.
The extreme distances between these cities results in the majority of Australians choosing to travel by plane to get from one city and coast to the other.
There are a large number of flight providers operating regular domestic flights Australia to connect these and other larger population centres. These flights are also invaluable for getting to and from isolated popular tourist locations within the interior of Australia, such as Uluru, more commonly known as Ayers Rock.
A good example to highlight the necessity of domestic flights in Australia is, for instance, say somebody living in Sydney who wishes to visit relatives or friends in Perth. As these cities are situated on the far east and west coasts respectively of this vast country, it would take on average around two days to travel the 2552 miles by road. In contrast, it would take a much more comfortable five hours in a direct domestic flight.
