This data set provides outlines for the maximum spatial extent of seabed geomorphic units for Australia's Exclusive Economic Zone, including the offshore island territories, but excluding Australian Antarctic Territory. Twenty-one geomorphic feature types were identified and mapped, following definitions published by the International Hydrographic Office (IHO, 2001). Value: The geomorphology of the seabed is used to constrained surface geology of the sea floor, important in resource exploration, marine zone management and for understanding the physical environment Scope: The area covered includes the seafloor within the Australian marine jurisdiction surrounding the Australian mainland and island territories of Christmas, Cocos (Keeling), Macquarie, and Norfolk Islands (Heap & Harris 2008).
