Dive into Whyalla's amazing underwater world of cuttlefish this winter

Find your wild this winter and swim with the spectacular giant Australian cuttlefish. Small groups can snorkel or dive with a trained guide and see these amazing sea creatures.

Every year between May and August, tens of thousands of cuttlefish descend into the idyllic cool waters around Stony Point, for the sole purpose of breeding.

The cuttlefish will light up with radiant colour and change shape and texture to replicate the marine environment as they move across the rocky reef in the northern Spencer Gulf.

People come from far and wide to experience the majestic cephalopods – which can span up to 60 cm and weigh up to 10 kg.

Recent upgrades to the cuttlefish dive site providing more parking, new bathroom and change facilities, vehicle drop-off and catering areas.

Whyalla City Council Mayor Phill Stone said the upgrades were a major benefit to the community, business owners and tourists who visit Stony Point each year to witness the incredible spectacle.

“The existing facilities were never intended to cater for such high demand, so it became critical to upgrade the area to make it safe for the increasing number of visitors, as well as better suited to the variety of experiences now on offer,” Mayor Stone said.

“We partnered with scientists and local cuttlefish experts such as Tony Bramley prior to commencing the work.

“They confirmed it would have negligible impact on the conditions that make the site so conducive to the cuttlefish, with regular monitoring throughout the project ensuring this was the case.”

Guided tours, snorkels, wetsuits and dive equipment can all be organised through local tourism operators or you can bring your own.

The location in South Australia is the only known dense aggregation spawning site for giant Australian Cuttlefish in the world.
