A comprehensive study of the 95 by-elections held in New South Wales since 1941 reveals significant changes in the causes of by-elections, their timing and the patterns of party canpetition to which they have given rise.
It also documents changes in the rate of turnout, the nature and size of Government and Opposition swings and the nature of any swing back. The study, the first of its kind for any Australian parliament, casts new light on the various aspects of the by-election process.
