Potential invasives

Potential invasives may be caused by the establishment of populations of species previously not found in Australia, or the expansion of a already established species into a new area or region. The relatively recent introduction of foxes to Tasmania is an example of this.Prevention of invasive animal problems is the most cost-effective course of action. In the failure of prevention, early detection is vitally important in controlling new incursions.

To help prevent potential invasive problems, governments need to put systems in place to ensure that ‘high risk’ species – those that could readily establish and become pests in the wild – are not imported into Australia. Click on the “Risk Assessments” link to the right to find information and guidelines on current risk assessment systems.
