Greg Foyster quits his job in advertising and decides to live more simply. Looking for inspiration, he and his partner Sophie cycle from Melbourne to Far North Queensland (via Tasmania, naturally) scouting out ideas.

Preposterously underprepared, they are propelled by the inspiring and eccentric characters they meet along the way - from a forest activist living up a tree to an 18th-century woodsman and a monk walking barefoot through Queensland.

Featuring eye-opening encounters with DIY downshifters and leading figures in sustainability, Changing Gears is a jaunty adventure that explores an important question for the future: can we be happier with less?
