Whyalla Australian Giant Cuttlefish

National Parks and Reserves

The annual migration of the Australian Giant Cuttlefish ‘Sepia apama’ to the waters of the upper Spencer Gulf to breed is one of the most spectacular natural events in the Australian marine environment and unique in the world to Whyalla.

Accessed directly from the shoreline; from May to August they are able to be viewed in the shallows and down to 6-8 metres approximately 200 metres offshore. In clear conditions they can be viewed when snorkeling and are best filmed diving.

At Stony Point at the Santos western boundary fence off Port Bonython Road there is a platform with seating and interpretive signage with a 60 metre pathway which leads down over the rocks to the high water mark. Launch yourself from this platform on a self-guided snorkeling adventure to witness these fascinating creatures.

At Black Point further along the coast there is a wooden staircase leading down to the rocky shoreline with additional concrete aprons and rails for diver’s use.

The water temperature is between 12°& 15°Celsius and we recommend you wear a thick wet-suit as the cuttlefish spawn during the winter months and therefore the water is quite cold.
