Bennelong and Phillip were leaders of their two sides in the first encounters between Britain and Indigenous Australians, Phillip the colony's first governor, and Bennelong the Eora leader. The pair have come to represent the conflict that flared and has never settled.

Fullargar's account is also the first full biography of Bennelong of any kind and it challenges many misconceptions, among them that he became alienated from his people and that Phillip was a paragon of Enlightenment benevolence. It tells the story of the men's marriages, including Bennelong's best-known wife, Barangaroo, and Phillip's unusual domestic arrangements, and places the period in the context of the Aboriginal world and the demands of empire.

To present this history afresh, Bennelong & Phillip relates events in reverse, moving beyond the limitations of typical Western ways of writing about the past, which have long privileged the coloniser over the colonised. Bennelong's world was hardly linear at all, and in Fullagar's approach his and Phillip's histories now share an equally unfamiliar framing.
