Not only are cuttlefish the ocean’s most intelligent invertebrates, but their look is also unbeatable! Three hearts, eight arms, green blood and “chameleons of the sea”… Cuttlefish – who aren’t actually fish but cephalopods – are fascinating creatures. And Whyalla, in South Australia, is the best place to see them.

The first time we randomly visited Whyalla, we first saw – and smelt – the factories and mines, beside one of the bluest water of the region. It was a big surprise to find out the coast is home to thousands of Giant Cuttlefish every winter. We swore to come back during the right season to see this unique show for divers and snorkellers.

What’s special with the Giant Cuttlefish in Whyalla?

Although Cuttlefish can be found elsewhere, Whyalla is the only known place on earth where thousands aggregate to reproduce. In 2016, the annual estimated population was more than 177,000 Cuttlefish!

It’s an amazing show. They change colours to attract each other or to camouflage with the nearby rocks and algae. Snorkellers and divers can dip in the middle of them. They don’t care and stick around as if no one was watching. They’re too occupied with their mating rituals to bother about stalkers. I had never seen Cuttlefish from that close before.

If you love Cuttlefish as much as I do, check this video to learn more about their mating ritual and how clever they are!

How to see the Giant Cuttlefish in Whyalla?

They only come when the water is colder, between May and July.

You’ll have to get wet to see them. Even if they stay in shallow water, they can’t be seen from the shore. The local dive shop can provide the adequate equipment for snorkelling and diving without being too cold.

The easiest entry point is at Stony Point, a 20-minute drive from Whyalla. A ramp will safely lead you over the rocks to the water. Black Point is another access point, but without a ramp, so divers will find it more challenging to go across the rocks with their equipment.

But don’t worry about where to go once you’re in the water. We saw our first Giant Cuttlefish one metre away from the shore in less than one metre of water.

Stony Point and Black Point have no facilities. You’ll have to change in your car. If you need, you can find showers at Point Lowly Lighthouse, about five to ten minutes away driving.

Is the water really cold?

Yes, it is between 11º to 14º. But the cold is not an issue if you have the right equipment. I lasted just under one hour for my dives on the first day and managed to stay more than 90 minutes twice on the second day.

Are you covered for scuba diving by your travel insurance? I recommend avoiding bad surprises if an incident happens. If you don’t have insurance, you may be interested in reading more about DAN and WorldNomads*.

Is it better to dive or snorkel to see the Giant Cuttlefish in Whyalla?

In Whyalla, the Giant Cuttlefish stay in shallow waters to be safe from predators like dolphins. Hence, it’s perfect for snorkelling. Our average depth while diving was around 2.5 metres only.

Still, I prefer diving. It’s more effort to put on all the equipment, but we could go very close to the Cuttlefish. They didn’t care about our presence nor our bubbles. It’s amazing just to stop there, a few centimetres away, and watch their colourful show.

Do you need a guide?

If you have very little experience in the water, it is always a good idea to hire a guide. It can also be an easy but amazing first diving experience if you’ve never tried it!

Although we are experienced divers, we enjoy diving with someone who knows the area and its inhabitants. It increases the chances of spotting more interesting things we may not even look for, like nudibranchs and eggs. Plus, it’s a perfect opportunity to get pics of you!

But if you have a buddy and don’t want to increase your budget, a guide is not necessary.

Are there other things to do in Whyalla?

It’s a big YES!

Whyalla is at the top of the Eyre Peninsula, and there’s a lot to do in that region if you have time. We haven’t explored it all.

We enjoyed a lot our night dive in Whyalla Marina, where we saw the cutest squid ever (bobtail) and loved our time with the seahorse! By the way, did you know seahorses are very talented for camouflage too? Before diving there, check out this website and this guide to learn more about what you may see.

During our first trip, we stayed in the north of the peninsula and went to Baird Bay to swim with dolphins and sea lions. We came back through the Gawler Ranges National Park and Lake Gairdner. A fantastic trip.

You can also go South, to Port Lincoln. You may spot Leafy Sea Dragons if you stop on the way to dive Tumby Bay. At Port Lincoln, you can dive with Great White Sharks and Sea Lions.

Where is Whyalla?

Whyalla is in South Australia, at the top of the Eyre Peninsula.

It takes almost five hours to drive there from Adelaide. It’s lovely to break the drive with a stop in the wineries of the reputed Clare Valley. You can also fly from Adelaide to Port Lincoln. You’ll then be 2.5 hours away from Whyalla.

Responsible Tip: Transport generates greenhouse emissions and contributes to global warming. Reduce air travel where you can. Driving is never eco-friendly, but it is still better than flying – especially if you carpool in a fuel efficient car!
