This paper explores the historical development of employment law in Australia, focusing on the landmark Harvester case of 1907. The Harvester judgment established the concept of a minimum wage in Australia, setting a precedent for the country's national minimum wage system. The paper examines the impact of the Harvester judgment on subsequent legislation and the evolution of minimum wage determination mechanisms, including the roles of the Australian Industrial Relations Commission, the Australian Fair Pay Commission, and Fair Work Australia (now Fair Work Commission). It also discusses the current minimum wage framework under the Fair Work Act 2009-2010 and the factors considered in setting minimum wages, such as living standards and the needs of families. The paper concludes by highlighting the enduring significance of the Harvester case in shaping Australian employment law and its ongoing relevance in the context of contemporary minimum wage determination.
