Graeme Wood is a most unconventional businessmen. He made his fortune from an online travel venture, Wotif, but now gives his money away to causes he supports. As a passionate environmentalist, he has bankrolled the Australian Greens. As a philanthropist, he has funded the Guardian Australia newspaper, universities and indigenous groups. Wood is critical of consumerism, rampant growth and free trade. He believes if we want to create a sustainable, innovative future for Australia, then we need more ‘ratbags’.
