D'Alpuget was an acclaimed author of biographies, novels and essays. Her political biography of Bob Hawke won the New South Wales Premier's Award. She also won the PEN Golden Jubilee Award, The Age Book of the Year and the Australasian Prize for Commonwealth Literature.
Her career began in journalism before she travelled the world, living in England, France, Indonesia and Malaysia. She returned to Australia at age 30 to become a novelist, exploring themes of power and politics. Her 1977 biography of Sir Richard Kirby received critical acclaim. In recent years, she wrote a five-part historical fiction series about Henry II and Eleanor of Aquitaine.
D'Alpuget first met Hawke in Jakarta in 1970. They reconnected when the then-prime minister asked her to write his biography. Hawke later said their romance began years before his divorce from first wife Hazel Hawke in 1995; he married d'Alpuget soon after.
Her family said she had asked loved ones to share her final message: "Our highest calling and greatest achievement is love, the rule of life. Love one another."
In a statement, the family remembered her as someone who "lived fearlessly and took delight in living." They said: "We will miss her force, her humour, her curiosity and her love beyond measure."
D'Alpuget is survived by her son Louis Pratt from her first marriage, three Hawke step-children and several step-grandchildren.
