Air Travel in Australia

"The modern airplane creates a new geographical dimension. A navigable ocean of air blankets the whole surface of the globe. There are no distant places any longer: the world is small and the world is one." - Wendell Willkie, 1948.

Now more than ever, aviation is connecting distant regions and continents, with the unprecedented traffic and passenger volumes. It enables international economic activity and spurs economic growth. The air and space industry contributed $5.2 billion to the Australian economy in 2010–11. This is 0.4 percent of Australia’s GDP in the same year.

In the year 2013, there were 87 million passengers carried in the Australian airspace, including 56 million domestic passengers and 31 million international passengers. The numbers are even more staggering knowing the population of Australia is only 23 million. Sydney and Melbourne are the two largest hubs for both domestic and international operations with 38 and 30 million passenger movements, respectively in 2013.

In this project, we visualize domestic and international airline activities in Australia. The chord diagram below presents the number of passengers traveling between the largest airports in the country. Only airports with more than one million passengers and pairs (chords) with more than 20,000 passengers per year are shown. The thickness of links be­tween airports displays the passenger count: thicker links represent more frequent links. Mouseover arcs and chords on the chord diagram or circles on the map to see the structure of air travel network and passenger count.
