Kenneth Walker’s 1956 publication, Industrial Relations in Australia, was acclaimed as the first full-scale analysis of the factors shaping Australian industrial relations. Significant developments during the ensuing years, however, necessitated a thorough reevaluation of the field. In his revised book Walker examines these extensive developments, reorganizes his approach, incorporates much additional material, and, in general, provides a more comprehensive view of Australian industrial relations. The organizing theme of this new work is John T. Dunlop’s concept of the industrial relations system, which the author applies to the Australian situation, distinguishing among national, state, industry, and plant systems.
