Central Eastern Marine Park links the continental shelf to the Tasmantid Seamounts, a far offshore chain of extinct undersea volcanoes. These seamounts and canyons interact with currents and ocean gyres resulting in upwellings that influence biological productivity within the region. This acts to concentrate marine life, and Central Eastern Marine Park attracts aggregations of tuna, whales and albatross that feed on abundant phytoplankton blooms.

The park begins 30 kilometres east of Coffs Harbour at the edge of the continental shelf on the New South Wales Coast. It covers 70,054 square kilometres and has National Park, Habitat Protection and Multiple Use zones. – Parks Australia

Central Eastern ranges from 123 to 5,205 metres depth, with an average depth of 4,062 metres. The majority of the Park (74%) falls within the abyssal zone (4,000-6,000 metres). [View on map] The mapped areas of the seafloor are dominated by Plane (67%) and Slope (19%) geomorphology. Seamounts/Guyots have been mapped in this Park. [View on map]
