This paper provides an overview of the Australian Plant Biosecurity System, based on the concept of a biosecurity continuum with pre-border, border and post border components. Particular focus is given to the post border component; preparedness and response to plant pest incursions. Also discussed are initiatives to incorporate all elements of biosecurity including potential production, social and environmental impacts within a uniform and consistent framework, the Australian Biosecurity System for Primary Production and the Environment.
