From their origins in the shadows of Australian public administration, ministerial advisers have been increasingly thrust into the limelight through scandals that appear on the front page of the newspapers. This book traces the rise in the power and significance of Australian ministerial advisers. It shows the fundamental shift of the locus of power from the neutral public service to highly political and partisan ministerial advisers. The book demonstrates that the introduction of ministerial advisers into the structure of the Executive has led to the erosion of the Australian system of responsible government. This is caused by a failure in the political, legal and managerial accountability frameworks surrounding ministerial advisers. Ministerial Advisers in Australia is the first comprehensive study of the legal and political regulation of Australian ministerial advisers. This book features material from original interviews with Australian Ministers and Members of Parliament, as well as several former State Premiers.
