Geology
The landform changes from grassy plains in the inner areas to salt marsh, shallow intertidal flats and rocky basalt platforms off the coast of Port Phillip Bay. Kororoit Creek flows through the Park into Port Phillip Bay. Regionally-significant geomorphological areas can be found at the wetland terrain at the mouth of the Kororoit Creek as well as at the extensive sand bars off Kororoit Creek.
The Park provides a protective buffer zone for the Wader Beach area of the Jawbone Flora and Fauna Reserve, which is located between Williamstown and Altona.
