About this audiobook

Five men vanished. A boat came back without them. In October 1880, government geologist Lamont Young arrived on the New South Wales Sapphire Coast to inspect the fevered Bermagui goldfield. Within days, he, his assistant Max Schneider and three experienced boatmen were gone, leaving behind a wrecked vessel, scattered belongings and a mystery that would haunt Australia for generations. Was it accident, murder, robbery or something darker born from gold fever? Drawing on archival records, witness statements and modern AI-assisted analysis, The Mystery Bay Murders reopens one of Australia’s most haunting cold cases and asks whether gold fever, failed investigations and buried motives concealed the truth all along.

5For almost 150 years, the Mystery Bay murders riddle has lingered on the New South Wales coast like a story the sea refuses to surrender.

Show all chapters

6In October 1880, five men vanished on the rugged Sapphire Coast. Among them were government geologist Lamont Henry Graeme Young and his assistant, Max Schneider, who had travelled to Bermagui to inspect what many believed might be one of the richest new goldfields in the colony.

7They are believed to have been accompanied by three experienced boatmen from Batemans Bay. The party set out into a landscape of surf, scrub and sudden fortune. None of the five men was ever seen again.

8Their disappearance shocked colonial Australia and drew attention across the British Empire. Newspapers speculated. Police searched. Rumors multiplied. A colonial Select Committee was appointed in 1883 and later concluded that the men had almost certainly been murdered and their bodies disposed of at sea.

9Yet the inquiry left its darkest question unanswered: motive. That single question has kept the case alive through generations of speculation, suspicion and silence.

10For generations, historians have regarded the mystery as nearly impossible to solve. Some believed the truth died with the killers. Others argued that too much evidence had vanished to ever identify those responsible.

11Yet modern technology offers a new way of looking at an old crime.

12Artificial intelligence cannot solve a murder on its own, nor can it replace historical research or police investigation. What it can do is analyse large bodies of evidence, identify relationships that human readers may overlook and test competing theories against the available facts. Used carefully, it becomes another investigative tool, not a substitute for traditional methods.

13This book combines archival research with AI-assisted analysis to re-examine the evidence gathered in 1880 and the parliamentary inquiry appointed in 1883, which reported the following year.

14Like many researchers before me, I began with journalist Cyril Pearl’s Five Men Vanished: The Bermagui Mystery, published in 1978. Pearl examined more than a thousand documents from the police investigation and parliamentary inquiry, producing what remains the most comprehensive published account of the case. His work has long shaped how the disappearance is understood.

15Following Pearl’s trail led me to the New South Wales State Archives in Sydney. With the assistance of archive staff, I obtained access to original police files, witness statements, official correspondence and Crown records. Over three intensive days, I examined handwritten letters from police officers, private investigators and witnesses, together with documents that had remained largely untouched for decades.

16Handling the fragile papers required gloves and patience. Unlike Pearl, however, I had one advantage unavailable to researchers in the 1970s: a smartphone that allowed me to photograph the documents for later analysis.

17The documents revealed a fascinating and often disturbing picture. They confirmed that newspapers had promoted Bermagui as the southern hemisphere’s “El Dorado” after rich gold was discovered on local beaches, sparking a brief but intense rush. They also showed that Young enjoyed an outstanding professional reputation and that his father, a retired British Army general, challenged aspects of the official police account. The records contained striking contradictions.

18One local official told the inquiry that one man could not possibly have murdered five people unless poison had been used. Historical records, however, show that the same official had previously been involved in violent frontier and bushranging episodes. Such details do not prove guilt, but they complicate any simple reading of the evidence.

19Other inconsistencies emerged. Police treated Max Schneider as a principal suspect despite his own disappearance. Some witnesses received payments for appearing before the parliamentary inquiry, while one of the most credible witnesses—the man who located the abandoned boat—was never called to give evidence. Young’s widow received compensation from the Crown, while the widows of the three boatmen depended largely on public donations. The reward offered for identifying the killers was never claimed.

20The fate of the physical evidence became especially important.

21I searched for records relating to Young’s personal belongings and geological equipment, which had reportedly been sent to the Mines Department in Sydney after the disappearance. Eventually I learned that bags containing clothing and equipment had been destroyed in a government fire in 1882.

22Much of the physical evidence had therefore vanished almost as completely as the men themselves. Most disturbing, no known photographic record of the recovered boat has survived.

23After weeks of reviewing witness statements and official reports, I faced a choice. I could rely solely on traditional historical interpretation, or I could see what modern analytical tools might contribute. I chose the latter.

24Using an AI-assisted criminology platform known as Crime GPT, I tested the available evidence against behavioural and probabilistic models commonly used in modern criminal analysis. The program highlighted patterns that suggested certain local officials and goldfield interests deserved closer scrutiny than they had previously received.

25These findings do not establish guilt. Rather, they identify investigative hypotheses based on patterns within the surviving evidence that warrant closer examination.

26The analysis also raised another possibility: if Young and Schneider were killed first, the later deaths of the three boatmen may have represented a second crime committed to eliminate witnesses. Under that interpretation, the famous discovery at Mystery Bay may have formed part of an attempt to disguise what had actually occurred.

27To test these ideas further, I used ChatGPT as a research assistant, asking it to evaluate alternative scenarios and consider whether modern technologies—including seabed mapping, forensic archaeology and behavioural analysis—might help identify burial sites or reconstruct the movements of those involved.

28The results did not solve the Bermagui Mystery. They did, however, raise important new questions. Those questions centre on whether greed during the brief Bermagui gold rush could have provided a motive; whether local officials occupied positions where conflicts of interest existed; whether weaknesses in the original investigation allowed crucial evidence to disappear; and whether today’s technology might reveal clues beyond the reach of Victorian investigators.

29This book explores those questions.

30It is not an attempt to rewrite history, but to re-examine it using every tool now available. By combining archival research with modern analytical methods, it seeks to shed new light on a mystery that has remained unsolved for nearly a century and a half.

31Chapter 1 – The Gold Rush Begins

32The first rumours reached Bermagui like sparks blown across dry grass. Along the lonely sweep of the Sapphire Coast, where fishing boats worked the white-edged surf and scrub pressed close to the sand, word spread that gold had been found. On 20 September 1880, Canadian prospector Henry Williams and three companions reported payable wash gold near the small settlement on the far south coast of New South Wales.

33Within weeks, the quiet coast was transformed by gold fever. Canvas tents snapped and sagged between the lake and the sea, campfires smoked in the damp evening air, and more than 2,000 men crowded into the district, drawn by the promise of sudden fortune. Williams named the field Montreal after his Canadian hometown.

34The new arrivals pitched camp on the narrow strip between Wallaga Lake and the South Pacific Ocean. Seabirds cried above the ring of picks, the scrape of shovels, the creak of pack saddles and the urgent talk of men chasing gold. Smoke hung over the tents, mingling with the smell of wet canvas, horses, boiled tea and churned earth.

35Each day brought another wave of arrivals: weathered miners, hopeful labourers, shopkeepers who had abandoned their counters, and men hardened by earlier rushes in Queensland, New Guinea and the inland fields. Shops in Cobargo and Bega closed as owners and employees joined the movement. From Mount Dromedary, Temora, Nelson, Goulburn and Wollongong, they poured into the new field, turning a remote coastline into a restless camp of ambition, exhaustion and disorder.

36On the last day of September, a special correspondent for the Sydney Morning Herald packed his travelling bags and made his way to the wharf, alert to every rumour and detail. Around him were the smells of coal smoke, damp rope and harbour water as the steamship Australia prepared to sail for the new goldfield. His first dispatch captured the excitement of a colony ready to believe that fortune might lie just beyond the next headland. “Very few of Madame Rumour’s darts are required to cause an excited rush of goldseekers in Australia,” he observed.

37Well before the 8 p.m. departure, “a hundred fine, stalwart fellows” had boarded. Many were seasoned miners, carrying the habits and scars of earlier work in New Guinea and Queensland. The voyage from Sydney Heads to Bermagui covered about 185 kilometres. Fares were £1 10s first class and £1 second class. The Australia anchored about a quarter of a mile offshore at 4.30 p.m. on 1 October, and the passengers—eager, tired and salt-sprayed—were rowed ashore in small boats.

38The Herald correspondent quickly noted shortages of food, tools and accommodation. Hunger and scarcity could be felt in the prices as much as in the camp itself: a long-handled shovel had attracted an offer of £3, meat and sugar sold for fourpence a pound, and flour cost fifteen shillings a hundredweight.

39A hotel and three boarding houses were under construction, but lodgings remained “very rough”.

40Authorities moved quickly to impose order on the swelling camp. A warden’s clerk and mining registrar were appointed, and New South Wales Inspector-General of Police Edmund Fosberry arranged for a sergeant and two constables to protect the miners—a small official presence set against a restless crowd of men hoping the field would make them rich.

41Warden Henry McCrummin Keightley reported to the Secretary of Mines, W. H. Suttor, that the miners were “a very orderly and respectable class”. Mining registrar A. J. Ivimey, of the Montreal Division, also expressed guarded confidence in the field.

42Ivimey acknowledged that the field had first been exaggerated and later unfairly criticised. Even so, he believed the ground already discovered could support its population for at least a year. Further promise appeared at Corunna Lake, seven kilometres away, where payable gold had been found. A smaller rush had also begun between Montreal and the lake, with yields of up to three pennyweights to the dish.

43Gold rushes brought sudden waves of miners seeking fortune, and in nineteenth-century Australia they helped shape settlements, economies and public imagination. Bermagui briefly felt that fever intensely. Such rushes were often marked by a buoyant belief that anyone might become wealthy almost overnight. At Bermagui, reports of gold-bearing sand on the beach helped turn local excitement into speculation, then speculation into frenzy.

44The Bermagui rush continued to expand. Within a week, the settlement had its own newspaper, the Bermagui Times, which the Herald correspondent described as “a very creditable production” that was both humorous and truthful. Other services soon followed, including a chemist, two stores selling everything from sardines, sugar and ink to miners’ rights, business licences, flour and shovels—and, unexpectedly, a circus.

45Yet even as the camp acquired newspapers, shops and amusements, doubts were beginning to gather beneath the excitement. The Herald reporter warned that the field was badly overcrowded and that many had been drawn there by wildly false rumours. Anyone intending to inspect it, the paper advised, should wait until government geological surveyor Lamont Young had submitted his report.

46Chapter 2 – Dead Men Tell No Tales

47That report was never written. Within 24 hours of arriving at Bermagui, Young and his assistant, Max Schneider, had disappeared with three local fishermen: Thomas Towers, the boat’s owner, William Lloyd and Daniel Casey, all reportedly respectable, sober family men.

48Only a day earlier, the new field had been crowded with talk of gold and easy riches. Now the same coast that had promised discovery offered something colder: a wrecked boat, abandoned belongings, the smell of seaweed and wet timber, and five missing men.

49The first official alarm came from an unsettling source. The same man who had reported the Montreal gold discovery would now report the disappearance of Young and Schneider.

50On 11 October, Montreal gold warden Henry Keightley telegraphed the Secretary of Mines, W. H. Suttor, with grave news. Young and Schneider were presumed lost at sea after their belongings had been found in a wrecked boat.
