Jeremy Clarkson, Richard Hammond and James May embark on a grand road trip across Australia's Northern Territory.

Tasked with picking a fast, luxurious GT for the trip, Clarkson chooses a BMW M6 Gran Coupe, Hammond a Bentley Continental GT V8 and May a Nissan GT-R, as the trio set out on an adventure that takes in crocodile-infested rivers, a race around a vast open-cast mine, an encounter with the world's longest lorries and the majestic scenery of one of the world's least-inhabited landscapes. Their dusty endeavour concludes with an unusual challenge involving a farm, their cars and 4,000 cows.

Also in this episode, Hollywood legend Kiefer Sutherland is the star in the Reasonably Priced Car. Show less
