It is hard to disagree with Bernard Keane, Terry Moran or Peter Shergold that public interest is determined through the democratic process and that public servants exercise their non-partisan professionalism by serving loyally the elected government, offering frank, fearless and robust advice in confidence.

I was pleased to see Terry Moran's additional points that the public service should be a professional and rational advocate of ideas that are in the long-term interests of the nation, and that it is in the area of long-term, transformational thinking that the service needs to lift its game.
