Marine pests can have a serious effect on ports and marinas.
Boats and vessels regularly pass through from different locations. They pose a high risk of spreading marine pests. These pests can damage your infrastructure and lead to fines or closures.
Protect your port or marina:
- Keep it clean and free from pests.
- Look out for boats and vessels that may bring pests into your waters.
- Learn how to identify pests.
Report anything you find.
Keep it clean
Keep marine pests out of your port or marina.
Anything that is submerged in water can spread marine pests. Keep watch for pests on incoming vessels and signs of pests in your waters and on your structures.
Protect your business and Australia:
Marine organisms that attach and grow on submerged surfaces.
Biofouling is one of the most common ways that marine pests spread. They can attach in large quantities on vessels and equipment and move long distances. They will then spread to the next location you use your equipment or vessel.
Biofouling increases the longer a vessel or structure is submerged or when antifouling paint is not regularly applied.
Marina operators can apply to be a certified clean marina.
This is a voluntary program. It involves training and accreditation, including ways to protect inland and coastal waterways.
