Nothing prepares a person for the job of chief of staff to a Commonwealth Minister. There are no professional development courses, no specialist recruitment agencies and no training manuals. It was into this vortex that Allen Behm became chief of staff to Greg Combet in 2009, the minister responsible for managing carbon pricing and the pink batts crisis. A seasoned troubleshooter, Behm has an uncanny ability to anticipate and deflect political crises. By his measure success as a chief of staff is being an invisible force. Invaluable insight from an experienced insider into the closed world of callow political advisers and their disastrous impact on the performance of many Ministers. - TERRY MORAN
