This project assessed the implementation and management of illicit drug diversion strategies in South Australia, Tasmania and Victoria. The objectives of the project were to: i) assess systematically how law enforcement drug diversion strategies in these states have been implemented and managed; ii) identify organisational procedures and systems and individual practices that facilitate or impede the implementation and management of drug diversion strategies; iii) identify evidence-based good practice of strategy implementation and on-going management; iv) develop an implementation matrix that identifies key success factors and critical impediments affecting the implementation and management of diversionary strategies; and v) develop an evaluation model that fosters transparency, strengthens performance with drug diversion initiatives and propels effective change. The first part of the report describes the national and state level context of the illicit drug diversion initiative, and establishes the analytical framework and theoretical concepts of the research. The literature review and policy document analysis provide depth and a holistic view of the issues. The research methods included: interviews with representatives from key stakeholder organisations, interviews with police officers, a police survey, and an assessment and treatment service survey.
