Great Southern Land

This week we see the mass movement we make across a sprawling land and how our daily habits push systems and networks of transport and data to breaking point. We follow the second busiest air corridor in the world - Sydney to Melbourne - as 150 flights daily prepare for the journey and watch Elyse Fordham as she prepares to captain the first flight of the day. Data visualisation reveals every flight in Australia over a 24-hour period.

In the second part of this four-part epic series, Steve Simpson explores our complicated relationship with the natural world. Attracted by its beauty and fearful of its dangers, Australians are forever locked into a battle with the elements.

Our Great Southern Land - Australia - is home to an amazing array of scenery - from the top of the Snowy Mountains to the tropical wilds of the Gulf of Carpentaria, to the irrigated farms of the Murray Darling Basin, the red heart of Uluru and to the ancient forests of Tasmania. In this new ABC series, Professor Steve Simpson takes us on a journey across Australia. From the skies, Steve uncovers the otherwise hidden patterns, rhythms, networks and systems that keep Australia on the move - fed, alive and thriving.
