In June 1998, on behalf of the Australian and New Zealand Environment and Conservation Council (ANZECC) Group of Agencies, the Department of Natural Resources and Environment (Victoria) appointed a consortium headed by Earthlines to conduct a best practice and benchmarking evaluation of park and cultural site interpretation and education services. The project is part of the ANZECC Benchmarking and Best Practice program – an initiative of the National Parks and Protected Area Management Working Group to establish best practice standards and models for park and protected area management. The terms of reference for the evaluation focused on organisational processes – that is, what constitutes best practice in organising and managing the delivery of effective park interpretation and education.
