Developing decision support models to evaluate biosecurity risks objectively helps decision makers manage the associated risks with importation of goods We report on the development of a prototype generic risk assessment model to determine the probability and consequences of a plant pest establishment and spread event for an infection point given the biosecurity risk organism arrives via various pathways The model has a number of submodels including entry pathway which models the ratio of infested units coming from any pathway supplying the infection point; establishment and spread which models the chance of an establishment and spread event occuring at an infection point; and consequences which models the consequences of any establishment or spread event occurring at the site Future research is planned to develop a generic input interface to generate a support tool to allow a user to investigate the impacts of alternative whatif scenarios and to test the model on realworld plant pest inputs
