This Report reviews the effectiveness of occupational health and safety management systems (OHSMS) in Australia and the barriers to their implementation. The need for such a review stems from the growing number of organisations using OHSMS and from criticism of the value of audit based models and the capacity of OHSMS to undermine independent employee OHS representation. The report addresses four questions.

1. How effective are OHSMS in delivering improved OHS outcomes?
2. What barriers exist to OHSMS success?
3. Lessons from Quality Management for OHSMS measurement and evaluation
4. How can OHS outcomes and OHSMS performance best be measured?
