Our lives depend on a healthy marine environment. We know that exotic species can throw our ecosystems out of balance. Do hitchhikers in ballast water and clinging to the bottom of ships arriving from other waters affect the health of Australian waters?

AUSMEPAs Marine Pests and Threats unit of work (here) for students and teachers puts that question into perspective. The newly renovated pages have just gone live!

If you wish to learn and share information on this interesting topic please visit our Curriculum Unit webpage at 

Use this website to research the facts and decide on the actions needed to prevent marine pests and threats coming to Australia either in ships’ ballast water or attached to ships’ hulls.
