Australia’s Ocean Frontier: Exploring the Eyre Peninsula, South Australia

On the Eyre Peninsula in South Australia, life is determined by the sea. Bounded by the wilds of the Southern Ocean to the south and west, and the calm waters of the Spencer Gulf, the Eyre Peninsula is ‘Australia’s seafood frontier’, South Australia’s wild ‘west coast’. Thanks to its nutrient-rich waters, the Peninsula is home to an abundance of marine life, from prize tuna to rare Australian sea lions. But the frontier is as true to this place as the seafood: the Eyre Peninsula region remains a place of rugged beauty and wildness, where the sea remains the ‘great maker and breaker’, creating fortunes and taking lives (Australian Geographic).

The dual nature of the sea is thanks to the geography of the Eyre Peninsula, which was named for explorer Edward John Eyre. To the west, the peninsula reaches the Great Australian Bight and Southern Ocean, where the Roaring Forties create cold winds and huge swells. To the east, the peninsula defines the calm waters of the Spencer Gulf.

At the tip of the Eyre Peninsula, the two huge peninsulas of Lincoln Bay and Coffin Bay national parks jut out east and west respectively, with landmass forming the shape of an anchor. The twisty coasts of these two peninsulas, a mess of coves, headlands and outcrops, give the sea a ‘split personality’, as it goes from rough waves to sheltered bay within metres.

Geologically, this is thanks to the influence of the ancient Gawler Craton, one of the world’s most stable landmasses, dating back as far as 2.4 billion years. These ancient granites hold fast at the bottom of headlands and cliffs, resisting the winds and swells of the Southern Ocean, protecting the younger layers of limestone above.

Off the coast of the peninsula, the Great South Australian Coastal Upwelling System brings cold, nutrient-rich waters to the surface from the edge of the continental shelf. These dissolved nutrients are at the base of the food chain, attracting fish, seabirds, penguins, sea lions, blue whales, and other marine life to the area. This marine life is a bounty that has brought people to the Eyre Peninsula for tens of thousands of years – but this abundance has always borne a cost.

Cape Catastrophe, 1802:

In February 1802, the HMS Investigator, commanded by Matthew Flinders, was anchored near a large island off the Jessieu Peninsula, south of Port Lincoln. Sailing from the south-west of Australia to Port Jackson (Sydney), the Investigator aimed to be the first ship to circumnavigate Australia, under the leadership of its young commander, 27-year-old Matthew Flinders. Though young, Flinders was an experienced explorer, having charted Bass Strait in 1798.

In need of water for the ship and crew, Flinders sent a party of men lead by the shipmaster, John Thistle, to the mainland. The conditions seemed calm and innocuous, and Flinders saw the cutter returning at dusk. Two hours later, the men had not returned. Flinders sent Lieutenant Fowler in search, but he came back alone. It became clear that the waters had changed and the cutter had crashed and the men – not strong swimmers – had been lost. The tragedy was confirmed the next day when Flinders and his crew found the wreck of the cutter.

In memory of the lost men, Flinders named the southern most point of the peninsula Cape Catastrophe, while a secluded bay nearby, where he left a copper plaque, was named Memory Cove, with the eight islands dotting the Thorny Passage each named after one of the lost men. The largest – Thistle Island – was named for John Thistle, who had served with Flinders for eight years. Flinders would write in his journal that:

‘His loss was severely felt by me; and he was lamented by all on board, more especially by his mess-mates, who knew more intimately the goodness and stability of his disposition’ (Flinders, A Voyage to Terra Nullius).

A couple of months later, Flinders would meet Nicholas Baudin at Encounter Bay, while charting the Fleurieu Peninsula. The ship safely reached Port Jackson in May 1802, successfully circumnavigating Australia on a voyage from 1802-3.

Flinders and his men were not the last to be swept away in the mercurial waters of the Eyre Peninsula. In the 19th century, boats remained the major source of transportation around the arid Australian continent. In total, 850 shipwrecks line the South Australian coast, most from the 19th century.

In the early 19th century, small wooden whaling vessels were frequently pushed off the coast and wrecked on the Eyre Peninsula. Crews encountered hidden reefs, and were blown ashore when as the winds suddenly changed. These wrecks line the coast on both sides of the Eyre Peninsula, providing a haven for marine life – corals, sponges, and sea stars – and ideal diving opportunities.

Tuna millionaires, shark singers, and oyster fishermen:

Yet, the sea can give as much as it takes away. When Ross Haldane and his family moved to Port Lincoln in 1952, the town was a sleepy shipping port. They had come from the coastal town of Port Fairy, Victoria, where they had spent seven years building by hand a 25 metre seagoing tuna vessel, on the basis of designs they had bought from a company based in Tacoma, United States. They named their vessel the Tacoma in honour of the company. Over the next forty years, they trawled the Spencer Gulf for prawns and southern bluefin tuna, spurring the commercialisation and expansion of Port Lincoln’s seafood industry. ‘Our whole life was seaward looking’ recalled Ross Haldane, the son of the oldest Haldane brother, who virtually grew up on the Tacoma in the 1950s.

The Haldanes, along with other families, including the Puglisis, Sarins, Lukins, and Santics, transformed Port Lincoln into the ‘seafood capital of Australia.’ Today, Port Lincoln has Australia’s largest commercial fishing fleet, with an annual tuna haul of 4600 tons. Giant boats punch into the mountainous seas, hauling up to 40 tons a day of tuna.

In particular, the growth of Port Lincoln was driven by Japanese demand for premium bluefin tuna for sushi and sashimi. The trade meant that local fishermen became ‘tuna millionaires’ overnight. Their palatial mansions – nicknamed ‘Dallas’ and ‘Dynasty’ by observers in the 1990s – lined Boston Bay and spread to the north-east of the city. Today, Port Lincoln has the most millionaires per capita in Australia. Most famous is Tony Santic, the owner of the three-time Melbourne cup winner Makybe Diva, who is honoured with a life-size statue on the Port Lincoln foreshore.

Port Lincoln’s seafood industry is highly technological and scientific. Practical science determines when and where trawling will occur. Largely successful attempts to conserve the stocks have made the Spencer Gulf into one of the best-managed fisheries in the world. Recent years have seen the development of a thriving aquaculture industry that farms species including bluefin tuna, yellowtail kingfish, abalone, mussels and oysters.

The coastal upswelling had proved a bounty to fishermen and women long before the emergence of the ‘tuna millionaires’. For the traditional owners of the land, the Naou and Bangarla people, fishing tuna was a vital source of sustenance. Archaeologists have found that the Lower Eyre Peninsula has the highest density of traditional tuna traps in Australia (Welz, 2002), which can be seen in Lincoln National Park and Coffin Bay National Park today. The Bangarla engaged in a ritual practice known as ‘singing to the sharks’, in which men lined the cliffs and sung out. Their chants were accompanied by women dancing on the beach. The idea was to encourage sharks and dolphins to drive fish to shore, where they could be more easily caught.

For others, the abundance of the sea was fleeting. In the early years of settlement, the Eyre Peninsula was a magnet for sealers, but seal numbers depleted so quickly that interest turned to whaling. Whaling stations were set up at Spalding Cove (in Lincoln National Park) and Coffin Bay, attracting international crews from France and the United States. Declining whale numbers meant that whaling became unviable as early as the late 1840s.

The small settlement of Coffin Bay then turned to another sea bounty: oysters. The first mention of the commercial exploitation of oysters near Coffin Bay appears in an extract of a letter from 28 April, 1848. By the following year, there was up to thirty cutters dredging the bay for oysters, and the settlement became known as ‘Oyster Town’. Huts were thrown up quickly for the fishermen’s families who had accompanied them to the area.

Coffin Bay
The calm waters of Coffin Bay are ideal for harvesting oysters.

Dredging for oysters was a hard life. Fishermen worked from dawn to dusk, fishing through the day, then cleaning the shells of debris in the evening. Oysters were then bedded down, live, in the water, until the fortnightly market day, which transformed the town into a hive of activity. Wagons would drive down from Port Lincoln and fill up with oysters, eaten in Port Lincoln and brought further afield to Adelaide. More than 250, 000 oysters were brought from Coffin Bay every fortnight.

The sea could not keep giving. Oyster populations rapidly declined thanks to rapid overfishing. From 1882 to 1891 the lack of oysters led to an official closure of the oyster fishery, leading to the decline of the town. The native oysters never recovered, an issue of debate among marine biologists. Some suggest that the fishermen did not return their shells to the sea (as they would only dredge them up next time) – meaning that young oyster spat did not have a surface on which to attach and grow. The historic Oyster Town and whaling station are now an archaeological site – including the remains of several fisherman’s huts – which can be explored on the Oyster Walk.

In the 1960s, the Pacific oyster was imported from Japan via Tasmania, starting the current Coffin Bay oyster industry. Known nationally and internationally, contemporary Coffin Bay oysters are a testament to the richness of the environment for oyster growth.

Things to see on the Eyre Peninsula:

The natural and geographic features that have made the Eyre Peninsula both a place of tragedy and fortune also make it one of Australia’s best holiday destinations. With rugged landscapes, panoramic sea views, and a wealth of natural wildlife, the Eyre Peninsula has so much to offer the traveller – and best of all, its remoteness from the population centres of the east coast means that you’ll have it all to yourself.

The major settlement, Port Lincoln, was mooted as a potential capital of South Australia in the 1830s. Sitting on Boston Bay – a natural harbour three times the size of Sydney Harbour (and as such, the largest harbour in Australia) – the town seemed like an ideal capital, with easy port access. But the idea was quickly abandoned thanks to the lack of freshwater on the peninsula.

Port Lincoln, South Australia
Boston Bay, Port Lincoln, is Australia’s largest natural harbour.

Lincoln National Park, on the other side of Boston Bay, is a 29, ooo hectare wilderness of granite headlands, secluded beaches, and offshore islands, with something to offer everyone. The headlands are a magnet for birdlife, with New England honeyeaters, silvereyes, and Port Lincoln parrots on the mallee coast, and hooded plovers, oystercatchers, and sea eagles on the beaches. On the southern side of the park are the immense Sleaford Bay sand dunes, shaped by the wild winds of the Southern Ocean.

The 31, 000 hectare Coffin Bay National Park, on the other side of the anchor-shaped peninsula, is likewise a patchwork of calm coves and sheer cliff faces. In the heart of the peninsula, there are ephemeral lakes and tea-tree scrub. The park was once covered in she-oak grassy woodland, cleared and grazed by pastoralists in the mid-19th century. Since the park was established in 1982, rangers and volunteers have devoted themselves to rehabilitating patches of she-oak grassy woodland. As part of this, the last Coffin Bay brumbies – wild descendants of Timor ponies brought to South Australia in 1839 – were relocated from the park in 2004. Native wildlife commonly seen here includes emus, goannas, and western grey kangaroos – while in winter, you might catch a glimpse of southern right whales or the great white shark from the Avoid Bay cliffs.

The town of Coffin Bay is a charming and sleepy fishing village, protected by a number of headlands, offering calm, pristine waters perfect for swimming. Seafood lovers should make sure to stop here to taste the world-famous fresh oysters at a local restaurant.

Head further west along the coastline, and you’ll reach the pristine beaches of Baird Bay, a tiny town with a population of only 3, with a cluster of houses, a caravan park, and a jetty. Despite its small size, Baird Bay attracts travellers from around Australia for the Baird Bay Ocean Eco Experience, the first tour company offering guests the opportunity to swim with bottlenose dolphins and Australian sea lions. The eco-friendly company is committed to protecting South Australia’s marine populations. When the company was first established in 1992, the sea lion population was around 35: today, it numbers over 120. The Australian sea lion, Australia’s only endemic seal, is officially regarded as endangered, with a global population of around 12, 000.

If you’re keen to see sea lions but not keen to jump in the water, the place for you is the Point Labatt Conservation Park. Point Labatt is home to mainland Australia’s only permanent breeding ground of Australian sea lions. Protected from mainland predators by sheer cliffs, sea lion pups learn to swim and play in the waters here, often aided by their mothers. At Point Labatt, pups are born every eighteen months, one in mid-winter, and then the next in mid-summer. They depend entirely on their mother’s milk for the first year, after which they begin chasing and (sometimes catching) fish. This long breeding cycle makes Australian sea lions particularly vulnerable, revealing the importance of sites like Point Labatt.

The nearby town of Streaky Bay was first sighted by the Dutch explorer Pieter Nuyts in 1627, and was named by Flinders after a ‘streaky’ discolouration he saw in the water, most likely seaweed. This charming seaside town is an ideal base for the western half the Eyre Peninsula, offering close proximity to  Murphy’s Haystacks, a remarkable rocks formation formed out of pink granite. The granite was originally buried deep under the ground – around 7 to 10 meters, but reached surface level thanks to rain erosion. Over time they were weathered into their distinctive shape by the heavy winds of the Southern Ocean. The ‘haystacks’ got their name because a passing traveller mistook them for particularly impressive haystacks. Because the owner of the wheat field they were on was called Murphy, the formations were nicknamed ‘Murphy’s Haystacks’.

The Eyre Peninsula ends at the town of Ceduna, west of Streaky Bay, and the last major settlement before you reach the vast desert of the Great Australian Bight and the Nullarbor Plain, stretching across to Western Australia. Ceduna, like the rest of the Eyre Peninsula, is famous for its seafood, producing fish, squid, shark, crabs, and oysters.

Head inland on the peninsula, and you’ll enter mallee country: a semi-arid environment defined by the presence of the hardy mallee eucalyptus. Unlike Mallee regions near the Murray River, the peninsula lacks fresh ground water, with water piped from Morgan, on the River MurrayDeep into the Eyre Peninsula you’ll find the outback Gawler Ranges National Park, home to rolling red-dirt hills, striking geological features, and an array of natural wildlife, including the endangered yellow-footed rock-wallaby and the southern hairy-nosed wombat. To the north of the Gawler Ranges, Lake Gairdner National Park is home to one of Australia’s most surreally beautiful landscapes, the endless white surface of the salt Lake Gairdner contrasting sharply with the surrounding red-dirt.
