This handbook completes Emeritus Professor Colin Hughes' major reference work on Australian government and politics in the 20th century. It is a sequel to three earlier volumes published in 1968, 1977 and 1986, which have become standard research tools for Australian historians and political scientists. It details, firstly, all members of all Australian ministries, cabinets and portfolios, with dates and notes, and secondly, voting information (both upper and lower houses of Parliament) for all general elections, Commonwealth, State and Territory, held between 1985 and 1999. It thus gathers together in the one book information which is otherwise scattered through a number of official publications, some not widely available. This consolidation and annotation follows the format established in the three earlier volumes and will join them as an indispensable reference work.
