The Currajong was originally a passenger steamer and later converted into a coastal collier. As one of the “sixty miler” colliers, she represents an iconic and important part of Sydney’s maritime heritage, supplying coal from the southern coalfields.

On 8 March 1910 the Currajong was struck amidships by the passenger liner Wyreema; she sank within minutes and one life was lost.

The wreck lies about 230 metres off Bradleys Head in roughly 26 metres of water, directly beneath the harbour’s main shipping lane, with thousands of people passing over the site every day on Sydney’s iconic ferries.

Diving the wreck is difficult and hazardous: it is usually only accessible in the early hours when vessel movements are minimal, and conditions include very low visibility, strong currents and occasional bull sharks.

HMAS Parramatta (D55) was one of the Royal Australian Navy’s first destroyers and among the vessels that formed the foundation of Australia’s fledgling fleet. Commissioned in 1910, she served in the Pacific and Mediterranean during the First World War, undertaking patrol, es**rt and anti-submarine duties.

Parramatta is also remembered for her association with HMAS AE1, Australia’s first submarine. On 14 September 1914, while operating off New Britain during the Australian capture of German New Guinea, Parramatta was the last vessel known to have communicated with AE1 before the submarine disappeared with all hands.

Following her decommissioning in 1928, Parramatta was stripped and sold for use as an accommodation hulk associated with works on the Hawkesbury River. After a series of ownership changes, the vessel was driven ashore and abandoned at Cascade Gully, where the remains of the hull survive today. In 1973, the bow and stern sections were recovered and preserved as memorials, with the bow displayed at Garden Island and the stern incorporated into a monument on the Parramatta River. Together, these surviving remnants provide a tangible connection to one of the Royal Australian Navy’s founding ships.

We've modeled one of the earliest known marine engines located in New South Wales waters!

The Mimosa was a coastal paddle steamer operated by the Illawarra Steam Navigation Company and was an important link between Sydney and communities along the NSW South Coast during the mid nineteenth century.

On 18 September 1863, while travelling north from Merimbula to Sydney, Mimosa struck an uncharted offshore rock near present-day Mimosa Rocks National Park. Although Captain Keft attempted to beach the vessel, water flooded the hull and the steamer sank in 15 metres of water less than a kilometre from shore. Most passengers and crew escaped in the ship’s boats, but two passengers, Mr and Mrs Ivell, lost their lives.

On 21 August 2026, our team travelled to Narooma, NSW, to dive and complete a full photogrammetry survey of the Lady Darling shipwreck. Thanks to Damien S, Scotty W, Ben M, Dean C and Grant T for the photos and model.

The team conducted two dives on the site using a mix of open‑circuit EAN38 nitrox and rebreathers. Conditions were ideal — a calm ocean, bright sun, and 10–15 metres of visibility, allowing for detailed imaging across the wreck.

The Lady Darling was an 895‑ton iron steamer, built in Liverpool, UK, in 1864. Measuring 73 metres in length, she operated as a collier transporting coal along Australia’s east coast.

On 10 November 1880, while en route from Newcastle to Melbourne, the vessel struck rocks approximately four miles south of Montague Island. Despite efforts to reach shore, the ship flooded rapidly, forcing the captain and crew to abandon her. All personnel safely reached Montague Island. For several days, the ship’s three masts remained visible above the surface before the vessel settled into deeper water.

In April 1996, local divers rediscovered the wreck lying upright in 30 metres of water on sand near Mystery Bay. Today, the Lady Darling remains one of NSW’s most historically significant and visually striking wreck dives.

Most people crossing Sydney Harbour have no idea what lies beneath them.

A newly released interactive 3D model reveals the TSS Currajong, a historic shipwreck sitting directly under Sydney ferry routes since it sank in 1910.

Created from more than 10,000 underwater images, the model lets you explore one of NSW’s most intact wrecks in incredible detail.

Would you dive a wreck sitting under one of the busiest harbours in the world?

On the 116th anniversary of its 1910 sinking, our latest interactive 3D model uncovers the TSS Currajong, a wreck that thousands unknowingly pass over every day on Sydney’s ferries.

The Currajong is one of New South Wales’s largest and most intact shipwrecks, offering a rare, tangible link to Sydney’s maritime past. As a remarkably preserved example of the sixty-miler trade, the wreck provides direct insight into the coastal coal economy, shipbuilding techniques and daily life at sea in the late 19th and early 20th centuries

The wreck sits directly under the harbour shipping lane and can only be safely dived when vessel traffic is minimal. The site is subject to strong currents, often has visibility under one metre, and attracts bull sharks in summer. The model allows members of the public and maritime archaeologists to explore and study the wreck in ways previously impossible due to the site’s diving challenges.
