Australian Marine Parks

Geographe Bay is a popular spot for diving, recreational fishing and nature-watching. Look for migrating humpback and blue whales that call in for a rest.

Geographe Marine Park, cupped in Geographe Bay, protects bountiful seagrass meadows.

These dense leafy places are home to numerous species of small fish and other marine animals, and provide safe nursery habitat for many species.

Juvenile western rock lobsters are an important part of the marine food web in the park.

The Noongar people have responsibility for sea country in the park.

The park is eight kilometres from Bunbury and Busselton and adjacent to the state-managed Ngari Capes Marine Park. Geographe Marine Park covers 977 square kilometres, with depths from 15 metres to 70 metres.

The National Park has Habitat Protection, Multiple Use and Special Purpose (Mining Exclusion) zones.


Join local guides for incredible diving and whale watching trips in Geographe Bay.

Information on visiting the adjacent Western Australian Ngari Capes Marine Park is available from Parks Western Australia.


Seagrass are the only flowering plants that can live underwater.

They’re more closely related to lilies than grasses, but get their name from their long, thin grass-like leaves.

They are important habitat for many marine animals and they help keep the water clear by trapping sediments and absorbing nutrients from coastal run-off.

You can help us learn more about seagrass by joining a local sea-grass monitoring group.

It’s a fun and easy way to contribute valuable scientific knowledge.
