The Australian Department of Defence is establishing a new Environmental Test Facility at Port Wakefield, South Australia. This paper outlines the requirement for the Environmental Test Facility, discusses its proposed capabilities and describes the unique problem in siting and establishing an Environmental Test Facility. The capabilities of an Explosives Environmental Test Facility are an inherent requirement to provide evidence to assess the safety and suitability for service (53) of items of explosive ordnance (EO) for use by the Australian Defence Force (ADF). The Australian Ordnance Council (AOC) is the body responsible for the provision of independent 3 advice to the ADF and was formed in 1975. It soon found that the capability for testing stores to the requirements of Council Proceedings was inadequate in a number of areas. This paper addresses the history of the process required to resolve the inadequacies, details the capabilities of the Australian Explosives Environmental Test Facility and provides some insight into the problems faced, and their resolution, in establishment and siting of a new Explosives Environmental Test Facility.
