The purpose of the audit was to examine the environmental management mechanisms in place across some of the major Commonwealth land management and oversighting entities. In particular, the audit examined Commonwealth environmental management practices to identify current strengths and weaknesses, and provide a framework and direction for the adoption of better practice and continuous improvement. The audit has not been designed to judge past Commonwealth performance using current environmental standards and practices. Rather, the audit focused on encouraging the development of better practice by illustrating the implications and lessons learned from past and present practices.
