Marine Pests
Introduced marine pests are marine plants or animals that are not native to Australia but have been introduced by human activities such as shipping. They have the potential to significantly impact our marine industries and our environment.
Australia has over 250 introduced marine species. Fortunately most have little impact but some, including several crabs, mussels, seastars and seaweeds, have become aggressive pests in some locations.
To protect our marine environment and industries, the Australian and state/territory governments, along with marine industries and marine scientists are implementing Australia's National System for the Prevention and Management of Marine Pest Incursions (the National System).
The National System aims to prevent new marine pests arriving, respond when a new pest does arrive and minimise the spread and impact of pests already established in Australia.
The Biosecurity Services Group (BSG) provides national leadership in the development and implementation of the National System and is the lead agency in implementing Australian Government responsibilities under the Intergovernmental Agreement on a National System for the Prevention and Management of Marine Pest Incursions (Marine IGA).
A marine pest website www.marinepests.gov.au is available and provides detailed information on the National System and sector specific marine pest management measures, including:
- marine pests and their impacts on industry and the environment
- identifying marine pests
- distribution of marine pests in Australia (interactive map)
- current marine pest outbreaks
- managing ballast water
- managing biofouling on recreational vessels, fishing vessels, commercial ships, non-trading vessels and petroleum vessels equipment and infrastructure
- the National System.
