Cod Grounds Marine Park is the smallest of all the Australian Marine Parks. It is the northernmost reef in a series that extends to the south and south-west, with predominately rocky substrate that provides habitat for a coral, sponge and seaweed communities. Humpback whales visit this area on their north-south migration, many species of seabirds use it for foraging and breeding, and grey nurse sharks can be found amongst its rocky pinnacles, ledges and sandy gutters.

The park is located offshore from Camden Haven, 30 kilometres south of Port Macquarie. It covers just 4 square kilometres and is zoned as a National Park. – Parks Australia
