The Captive Republic: A History of Republicanism in Australia 1788-1996, Cambridge University Press, Cambridge and New York, 1996
This first comprehensive history of republican thought and activity in Australia traces debate around an Australian republic from 1788 to the present. It explains the pivotal role played by republican philosophies, both before and after federation, and illustrates the striking similarities between the arguments of both republicans and monarchists in the 1990s and those which existed 150 years ago.
