Geoffrey Robertson is one of Australia’s best-known expatriates. The UK-based human rights advocate and occasional Hypotheticals presenter has been mixing with the famous and infamous ever since he exploded onto the swinging sixties scene to help defend the Oz magazine obscenity case. "People often come up to me and say 'Oh you Australians are so refreshing.' What they mean is 'Rack-off you loud-mouthed colonial.'" He is the consummate self-made man and his razor-sharp legal mind gives short-shrift to the nature-nurture debate. Genes don’t fit his world view. But when he starts looking into his family tree in Who Do You Think You Are?® he finds some remarkable parallels in the expatriate lives of his forebears. Is Geoffrey Robertson the descendant of a right royal bastard or a very wiley entrepreneur? The jury is still out.
