From Philip Mussared, (then, 2003) Deputy Secretary, Department of Treasury and Finance, Tasmania

"Over a period of time, Don has achieved a "quiet revolution" in our approach to leadership and management. I am convinced that Don's ideas, tools and influence are helping us to better achieve the results we (and our stakeholders) need, and to learn more effectively as a high reliability organisation. I've benefited personally from Don's work with our executive team, as has the team generally. As Don's action learning approach has been taken up by our managers, we are seeing more effective leadership being demonstrated throughout Treasury. Don knows his field, thinks carefully about these issues and is a highly skilled practitioner."
