This respected and authoritative text focuses on the fundamental principles that underpin all environmental initiatives, equipping the reader with the ability to approach any environmental law with a clear understanding of how it is intended to work and how it will be interpreted. The sixth edition has been updated to include new developments in policy, case law and legislation, and also reflects the ongoing international influence upon the development of Australian environmental law and policy. This book is aimed at both undergraduate and postgraduate students of law, environmental science, environmental management and environmental economic disciplines, and is a valuable resource for non-government organisations, public servants, corporate officers and other practitioners.
