and appropriate biosecurity legislation and enforcement, 
which is supported by strong infrastructure, quarantine and 
inspection facilities, including diagnostic support services 
(well established) {5.4.2, 5.6.2, 5.6.2.2, 5.7}. Risk 
assessment could be used by businesses to engage 
different sectors in the prevention and management of 
biological invasions (established but incomplete) {5.6.2.1}. 
Adoption of regulated species lists with explicit prohibition of 
or permission for the importing of specific alien species, 
underpinned by risk analysis, has been an effective 
prevention strategy (well established) {5.6.2.1, 6.3.1.4}. It is 
estimated that nearly 70 per cent of marine invasive alien 
species established worldwide were introduced via
biofouling (established but incomplete) {5.5.1}.
