Marine pests threaten Australia's unique marine environment and marine industries

Over 250 introduced marine plants and animals have hitch-hiked to Australian waters on vessels of all types from yachts to commercial ships. Some have taken over habitats from our native species, changing our coastal areas and damaging our fishing, aquaculture and tourism industries.

Getting rid of marine pests is virtually impossible. Like cane toads and rabbits, they multiply quickly and force out native species. Others (like toxic algae) can pose a threat to human health. More on the impacts of marine pests

Stopping the spread

To protect our marine environment and industries, the Australian and state/territory governments along with marine industries and marine scientists are implementing the National System for the Prevention and Management of Marine Pest Incursions.

The National System aims to prevent new pests arriving, respond when a new pest does arrive and minimise the spread and impact of pests that are already established in Australia.

All vessel owners and operators and marine aquarium suppliers have an important role in stopping these pests. To discover what you can do, click on the tab that applies to your vessel class or marine industry.
