The document outlines the task of creating a timeline to display the history of occupational health and safety laws from ancient times to modern Australian regulations. It provides evaluation criteria for the timeline, including requirements to cover early OHS laws before the Common Era, developments in the UK during the industrial revolution, and the formation of international and national regulatory bodies. The timeline must also address the recent harmonization of Australia's work health and safety laws and include both in-text and end references presented in ECU referencing style. Professional presentation with images and formatting is expected, with the timeline conveying key events and milestones in the development of OHS laws over time.
