Discovery Bay Marine National Park:

The park covers 2830 hectares adjacent to Cape Bridgewater along the coast from Blacks Beach to Whites Beach and offshore to three nautical miles. Between Whites Beach and Cape Duquesne the park boundary commences 500 meters from the coastline. The park abuts the Discovery Bay Coastal Park. The wrecks of three wooden sailing barques, the Jane, the Ann and the Marie, are thought to be in the vicinity of the park. 

​

Diving Conditions :

The dive site is exposed to storms and south-westerly swells of the Southern Ocean, and resulting high deepwater wave energy. The Zeehan Current is influential moving water in a south-easterly direction through the park. The warm Leeuwin Current flows east along the southern coast of Australia and may influence water temperature, particularly during La Niña years.

 

Marine Habitat:

Western Blue Groper have been observed in the high profile reef systems in 50m  of water west of Cape Duquesne.  The open waters of the park are  a probable habitat for the threatened migratory southern bluefin tuna, grey nurse shark, and White Shark . The intertidal reef provides an occasional haul-out area for state  Fur Seals. Southern right whales, blue whales and southern elephant seals have been recorded in or near the park.

​

Access:

Beach access is from Whites Beach and Blacks Beach while boat access  is from Bridgewater Bay and  Portland Harbour.
