The push to apply corporate governance arrangements from the private sector into the public sector is a manifestation of the ongoing search for ways to improve accountability and performance. This small interview study reports on the experience of senior Commonwealth public servants and board directors trying to work within the corporate governance frameworks set out in the Commonwealth Authorities and Companies Act (1997) and the Financial Management and Accountability Act (1997). It suggests that lines of accountability can be blurred, formal authority can be subverted, and safeguards to protect the public interest, against harms such as political patronage, may be weak or absent. Many agencies do not have appropriate procedures for assessing their own governance arrangements. There is considerable resistance to the notion that a central authority should be established with the dedicated purpose of overseeing governance arrangements and practices in the Commonwealth.
