This is the first comprehensive study of the development of the central institution of government over the first century of its life. Based on the author's detailed archival research and 30 years' experience writing about central government in Australia, it provides an understanding of both the history and the working of the institution. Patrick Weller has written a detailed history, as well as a politics primer. It is book packed with political insights and anecdotes, with lively portraits of our prime ministers and their cabinet colleagues along with the airing of many fascinating details of memos and meetings long buried in the archives.
