This past January, a collaborative research team comprising maritime archaeologists from the Silentworld Foundation and the museum conducted a shipwreck survey at Kenn Reefs in Australia’s Coral Sea Territory. The team relocated a number of historic shipwrecks documented by the Queensland Museum in the 1980s, as well as four new wreck sites. The Kenn Reefs complex is a seamount system located within the ‘Outer Route’, a seaway used by nineteenth-century mariners in an effort to avoid the Great Barrier Reef when travelling to and from Australia’s east coast. The discovery of multiple shipwreck sites of nineteenth-century vintage at Kenn Reefs demonstrates the hazards faced by mariners as they transited through waters that were insufficiently charted. Field investigations included reef-top inspections, metal detector and magnetometer surveys, and diver-based ground-truthing of observed features and buried anomalies.

“People think ‘That was it, the deep oceans became accessible to man with Titanic in 1985’. Well, that’s completely false.”

David Mearns is one of the world’s pre-eminent shipwreck hunters. His company, Blue Water Recoveries, has an 88% recovery rate. He discovered the HMAS Sydney, and the Kormoran, the HMS Hood, the Royal Navy flagship sunk by the Bismarck, Vasco da Gama’s Esmerelda (which sunk in 1503), the Lucona a cargo ship sunk by a time bomb that murdered its crew and the Rio Grande, the deepest shipwreck ever found – at 5,762 metres.

How to Become a Shipwreck Hunter

But Mearns wasn’t interested in history at University. He actively avoided it, instead, he concentrated on getting degrees in marine biology and later, marine geology. He found work in the offshore industry, helping search and recovery for the US Navy. This is what sparked his now lifelong obsession as a shipwreck hunter: part detective, part archaeologist, part deep ocean adventurer – and historian.

His passion for the stories of the past drives him thousands of metres below the waves.

Last week we unveiled a new large-scale embroidered work by Melbourne textile artist Melinda Piesse at the museum. Known as the Batavia tapestry (2017), it illustrates the tragic story of the wreck of the Dutch East India Company (VOC) flagship Batavia in the Indian Ocean, off the coast of Western Australia, on 4 June 1629 and the sorry fate of the ship’s company.

This week a very special piece of pewter is coming to the museum … the Hartog plate, on loan from the Rijksmuseum to mark 400 years since Dutch mariner Dirk Hartog made the first recorded European landing on the west coast of Australia in October 1616. As a testimony of his visit, Hartog left behind an inscribed pewter plate that is recognised as the oldest European artefact found on Australian soil.

Flush with the exhilaration of discovering site KR12 and the ship’s bell, the team set to work the following morning (16 January) to document finds. John, Jacqui, Pete, Renee, Lee and Jules entered the water and conducted a baseline offset survey of the site, followed by detailed recording of the cannons and anchors. Jules then took close-up photographs of each anchor and cannon while Lee carried out a photogrammetric survey of these and other features, including the rudder hardware found in association with the bell.

While the dive team was busy documenting sites KR10 and KR11 on the morning and afternoon of 14 January, the magnetometer team took advantage of the calm weather and sea conditions to run a survey along the outside of the entire Kenn Reefs system. The first area surveyed was along the outside fringe of the ‘foot and ankle’, with specific emphasis placed on detecting offshore components of known shipwreck sites (such as KR1, KR2 and KR4). Because sea conditions were calm, the team also ‘deployed’ Lee on a tow-board behind the magnetometer.

The tow-board (also known as a ‘Manta-board’) is a flat, hydrodynamic-shaped board with handles that is connected to a towing vessel with a length of line. The person using the tow-board grips the handles, is pulled through the water at low speed, and can visually search the seabed for shipwreck material. Most tow-boards are designed so that their users can turn, dive and ascend through the water column at will, simply by changing its orientation with the handles. Lee was positioned 10 metres behind the magnetometer in the hope he might be able to visually spot and identify any anomalies it detected.

One of the major goals of the Kenn Reefs expedition was to find Hope, the small cutter built from material salvaged from Bona Vista, and later lost during the rescue of the brig’s crew. According to historical accounts, two boats were sent from the rescuing vessel (the ship Asia) to Observatory Cay, where they recovered most of Bona Vista’s crew, the brig’s allocation of specie (gold and silver coin brought aboard Bona Vista for trading purposes), and brought them aboard Asia. A skeleton crew of thirteen and the personal belongings of all of the brig’s officers and men remained aboard Hope, as did unspecified salvaged goods valued at £1,000. However, as Asia got underway and took Hope under tow, tragedy struck:

The Australian National Maritime Museum and Silentworld Foundation recently led an expedition to the Australian Coral Sea Territory to conduct an archaeological survey of historic shipwrecks lost at Kenn Reefs during the nineteenth century. The Kenn Reefs expedition is a continuation of an ongoing collaborative project between the museum and Silentworld Foundation that commenced in 2009 and led to the discovery that same year of the wreck of the colonial government schooner Mermaid (lost in 1829 on what is now known as Flora Reef). No less than eight vessels are known to have wrecked at Kenn Reefs between 1828 and 1884, and most grounded in relatively close proximity to one another on the largest of the southernmost reefs in the chain, as it was located within an oft-travelled shipping route, but poorly charted until the mid-nineteenth century.

Last Thursday night saw the launch of the museum’s latest roof projection, A chance encounter, to commemorate the 400th anniversary of Dutch mariner Dirk Hartog’s landing on the west coast of Australia in the VOC ship Eendracht. To mark his landfall on 25 October 1616, Hartog left behind an inscribed pewter plate in Shark Bay, Western Australia, which provides tangible evidence of one of the earliest European encounters with Australia.

On a cold sunny morning in June 2016, Silentworld Foundation Director and maritime archaeologist Paul Hundley steered the survey vessel Maggie III into shallow water at the head of Berrys Bay on Sydney’s North Shore. Accompanying him were the museum’s maritime archaeologists Kieran Hosty and myself, staring intently at a laptop computer as it displayed readings from a marine magnetometer towed a short distance behind the boat. As Maggie III’s hull glided through water less than a metre deep, we watched for any indication that remnants of a unique sailing ship might lie buried in the silt below. Continue reading

Four hundred years ago, Dutch mariner Dirk Hartog (1580–1621) sailed into history when, on 25 October 1616, he made the first documented European landing on the west coast of Australia in the Dutch East India Company (VOC) ship Eendracht (‘Concord’ or ‘Unity’). Today his name is synonymous with the inscribed ‘Hartog plate’ that marked his landfall at Cape Inscription on Dirk Hartog Island in Shark Bay, Western Australia. This evocative pewter relic, now held in Amsterdam’s Rijksmuseum, provides tangible evidence of one of the earliest European encounters with the mysterious Terra Australis Incognita – the unknown southern land.

New South Wales hosts a wide variety of historic shipwreck sites. These range from large, fully exposed and intact hulls to smaller, largely disarticulated, dispersed, and buried structural components and artefacts. The environments in which these sites exist also differ significantly in terms of seabed composition, water depth and water clarity.

Almost 400 years ago, in the hours before dawn on 4 June 1629, a flagship of the Dutch East India Company (VOC) was wrecked upon Morning Reef near Beacon Island, some 60 kilometres off the Western Australian coast. It was the maiden voyage of the Batavia, bound for the Dutch East Indian colonies of modern-day Jakarta, but the tragedy of shipwreck would be overshadowed by the subsequent mutiny among the survivors on the isolated Houtman Abrolhos Islands.
