Giant Whyalla Cuttlefish Snorkel | Tours | FAQs

Swimming with the giant Whyalla cuttlefish is one of the great wildlife experiences you can have. From May to the end of August, Whyalla, at the top of the Eyre Peninsula in South Australia, becomes the giant cuttlefish capital of the world. Tens of thousands of cuttlefish arrive near Point Lowly to breed.

What makes this experience so good is that the cuttlefish are within metres of shore so swimmers of all abilities can swim ans snorkel with these intriguing creatures. Their pulsating colours, huge eyes and long arms coming from their head make them a fascinating sight.

When can you see the Whyalla Cuttlefish?

The giant cuttlefish start appearing in May but peak cuttlefish viewing time is June and July. Their numbers start to thin out in August. Depending on the season, even in early August the congregation can be over. For timely updates contact the Whyalla Visitor Centre.

As for the best time of day, we found mornings worked better. There was less wind in the mornings, so the water wasn’t as stirred up. If you can time your snorkel with an incoming tide, you’ll find the cuttlefish get pushed even closer to shore.

Why do the Cuttlefish come to Whyalla?

Whyalla is unique in the world for its wintertime aggregation of giant cuttlefish. Nowhere else on the planet do they come together in such large numbers to spawn.  So, what is the attraction of the shallow waters near the industrial city of Whyalla? Marine scientists believe the rocky ledges along the coast of the Upper Spencer Gulf Marine Park are the perfect habitat for the giant cuttlefish to lay their eggs. In their thousands, the cuttlefish arrive to compete for a mate, deposit their eggs then die.

What will you see?

Lots and lots of giant cuttlefish, this isn’t like trying to spot a leafy sea dragon! There are cuttlefish everywhere and seeing them in such numbers is an amazing sight. They are extraordinary looking creatures. Here are a few things you will see:

  • Size – cuttlefish can be up to 60cm long and weigh 10kg
  • Tentacles and arms – cuttlefish have 8 long arms and 2 feeding tentacles flaring from their head. They mate head-to-head, with their arms entwining.
  • Chameleons of the sea – one of the most striking things you will see is how they change colour. Watch them swim over different surfaces and waves of colour will pulse across their body. It is incredible to watch, you will think you’re seeing things. Their ability to change color is used as camouflage against predators and to compete for mates with other males.
  • Shape-shifters – Cuttlefish can not only change colour, but they can also change shape and texture. As you snorkel, you’ll see the different shapes they can take. You’ll also see their texture change as they swim over rocks and sand.
  • They can swim forwards and backwards – cuttlefish can swim head or tail first, propelled either by a jet of water from their siphon or the rhythmic undulations of their fins.

More Whyalla Cuttlefish Facts

  • Cuttlefish have 3 hearts. Two are used for pumping blood to the gills and the other pumps blood to the rest of the body.
  • Those 3 hearts pump green-blue blood around. Mammals have iron-based hemoglobin in their blood that makes it red. Cuttlefish have a copper-based protein called hemocyanin that makes their blood the different colour.
  • The cuttlefish bone you often see washed up on the beach is porous. The cuttlefish pump air into the bone to control their buoyancy.
  • Cuttlefish eyes – Their large eyes are not only striking, but they are also incredibly complex. Cuttlefish are colour blind, but they are highly sensitive to polarized light. Their unusually shaped pupils give them almost 360-degree vision.
  • Despite their name, cuttlefish are not fish. They are a type of Mollusk known as a cephalopod (which is Greek for head-foot). They are closely related to squid and octopus.
  • Many more male than female cuttlefish arrive in Whyalla which is why there is such fierce and spectacular mating rituals to attract a female.

Is swimming with the Whyalla Cuttlefish easy?

One of the best things about this experience is how accessible it is. Seeing the Whyalla cuttlefish doesn’t involve expensive boat trips, snorkeling in deep water or trekking to a remote location. They are only metres from shore near one of South Australia’s biggest regional centres.

Even if you are not a confident snorkeller, you can float over them on a lilo with a facemask on and still see them. If you want to stay dry, you can view them from a glass bottom boat.

Is swimming with the Whyalla Cuttlefish safe?

Swimming with the giant cuttlefish is a safe activity. The only sharks you are likely to see are harmless Port Jackson Sharks grabbing a quick snack. Of course, with so much food around the cuttlefish do attract some predators. Dolphins and seals come in to eat the cuttlefish, but they are no threat to swimmers.

There are two challenges for this activity. The first is dealing with the cold water, we’ll cover what equipment you need in the next section. The other hazard is the slippery, uneven rocks that lead to the water’s edge. If you take your time and use the chain rail at Stony Point to steady yourself, you should avoid an uncomfortable slip onto the rocks.

What Equipment do you need to Swim with the Cuttlefish?

The one thing you need to be ready for is the cold. In winter, South Australian waters are between 12 and 15 degrees so be ready to cover yourself in as much neoprene as possible. You will need a full length 5mm – 7mm wetsuit, gloves, boots and a hood. We opted not to get a hood but in hindsight we wished we had. When the water hits your head, you sure know you’re alive!

We have snorkelled in the chilly Ewens and Piccaninnie Ponds and the shallow Whyalla water in winter was colder. It was about 12 degrees for our swims in June. Have something warm to change into for when you get out. If you have a waterproof camera or GoPro, bring it along because you can get some great pictures.

Can you hire wetsuits in Whyalla?

In Whyalla you can hire all the equipment you need from Whyalla Diving Services. They recommend you book a time to get your gear fitted at the time of collection. We hired our wetsuits from a local dive shop in Adelaide so we could drive straight to the coast and start snorkelling. It is not important where you get your gear, just make sure you are prepared for the conditions.

Do need a permit to swim with the Whyalla Cuttlefish?

There are no permits, entry fees or park passes required to swim with the Whyalla cuttlefish.

Where can you see Whyalla Cuttlefish?

The cuttlefish breeding grounds are 30 minutes from the centre of Whyalla. They stretch from Fitzgerald Bay, around Point Lowly to Black Point and False Bay. A spot called Stony Point is the most popular place for getting into the water to swim with the cuttlefish. Look for the turn off from Port Bonython Road as you drive towards Point Lowly.

Stony Point has plenty of parking, change rooms, toilets, a shelter and the best set up for entering the water. As the name suggests, the foreshore around here is quite rocky and negotiating it with your snorkelling gear, let alone a scuba rig, can be a bit tricky. Stony Point has a boardwalk and chain handrail to help you into the water over the uneven surface.

There will be fewer people away from Stony Point. If you opt to see them closer to Point Lowly be aware of the currents that are stronger there and look out for boats. You can also get into the water closer to Black Point but there aren’t any facilities and parking and getting to the water is trickier.

Can you Dive with the Whyalla Cuttlefish?

Even though the giant cuttlefish are in shallow water, diving is a popular way to view them. It is not a deep dive, you’ll be 4-6 metres of water, but diving is the perfect way to get up close to the cuttlefish and feel a part of their world. Our experience has been that even though it is a shallow dive, you can expect to be in the water for less than 60 minutes. All the divers we spoke to came out feeling quite cold.

Whyalla Cuttlefish Snorkel

The easiest and most popular way to see the Whyalla Cuttlefish is to snorkel with them. You can see the cuttlefish in as little as 1 or 2 metres of water. Even though you are on the surface you will need a full-length wetsuit, boots, gloves and a hood. While you will need your face mask and snorkel, you could do the activity without fins. There are so many cuttlefish, you don’t have to cover a big area so if you are a bit uncomfortable kicking with fins you could get away without them.

If you travel with young swimmers, we saw some families take to the water with lilos. Because the water is shallow and quite clear, the kids were able to lie down with a facemask and snorkel and see the cuttlefish as they floated around. It’s a good option if you haven’t mastered using fins or want to avoid the worst of the cold water.

Can you take Pictures of the Cuttlefish?

One of the amazing things about this experience is that you can so close to the wildlife. So often in a marine environment you find yourself chasing fast moving creatures but that is not the case here. The cuttlefish are so intent on breeding they are little bothered by people. You won’t need a zoom lens; you will be able to get within arm’s length of the cuttlefish – but of course no touching.

If you have a waterproof camera, you will get some great pictures. We found visibility is best in the mornings. The other challenge for snorkellers is getting down to the cuttlefish while you are wearing so much neoprene. If you are a keen photographer, maybe think about wearing a weight belt. Or you can do what we did and take turns holding each other underwater – that’s how shallow it is!

Glass Bottom Boat Tour

You can see the cuttlefish in Whyalla without even getting into the water. If you like the idea of staying dry and warm, you can on a glass bottom boat cruise over the cuttlefish. The tours leave from a couple of locations near Point Lowly. The cruises are not only a good way to stay dry and warm, they are also a way to see some of Whyalla’s other marine life.

Snorkelling + Diving Guided Tours

If you want your whyalla cuttlefish swim to be hassle free, you can go on snorkelling and dive tours. Whyalla Diving Services, PureSA, and Experiencing Marine Sanctuaries (EMS) all offer either snorkelling or scuba packages. If you are a bit nervous of the water and want a snorkelling buddy, one on one guided swims are also available. Having said all that, if you are comfortable in the water and have the right gear, this is the type of snorkel you can manage on your own. You are in shallow water and the cuttlefish are easy to spot.

Can you Catch Giant Cuttlefish?

You cannot fish for the giant cuttlefish in the False Bay/Point Lowly spawning area. Fishing is allowed for other species in the area but there is a year-wide ban on taking the cuttlefish.

Whyalla Accommodation

There is a range of accommodation options in Whyalla. We stayed at the Sundowner Cabin and Tourist Park. Located just outside the town centre the park was clean, tidy and a great place for a few nights. The back gate leads through to the Sundowner Hotel which has good pub meals. If you are diving or snorkeling the little balcony on the cabins is perfect for hanging out your wetsuit to dry. There are also campgrounds at Point Lowly and there are cottages at the Point Lowly Lighthouse.
