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. On the ground, Steve is stuck in traffic, becoming one of the 12 million people - more than half the country's population - trying to make their morning commute. And as the roads and trains fill, we join Sydney's Traffic Management Centre as they try to keep as many people on the move as possible. It is a different type of horsepower as Steve has a punt on the Melbourne Cup, joining Mark Davies whose job it is to move the 100,000 people in and out safely on that day. And finally Steve explores the movement of data as he visits the AFL Grand Final and learns how half a million text messages are delivered during the game.
