Joadja

Shale mining and the settlement

Before the company town emerged, several parties were already working the shale. In 1874 Edward Carter, George Larkin, and John de Villiers Lamb with William Brown held separate mining interests in the valley. Historian Ian Jack describes bullock teams hauling shale across the valley floor and up a steep track to the plateau. Each party depended on access through land associated with the others: transport was a challenge well before the later railway incline.^[15]

Joadja grew around the mining and processing of kerosene shale. The State Library’s Fell family papers identify engineer James Walter Fell as the planner of the shale-oil works in 1877, and record his continuing consultancy until 1881. Council’s heritage study describes a company settlement established in the late 1870s. Industry brought homes, a school and community institutions into a valley whose steep sides made transport an essential part of the enterprise.^[8]

The Australian Kerosene Oil and Mineral Company developed mines, retorts and a refinery alongside the settlement. Council’s heritage study describes shale being brought from the valley sides to retorts, where crude oil was extracted before refining and packaging. The works also produced other materials, including waxes and candles. A contemporary account in New South Wales in 1881 reported about 50 men winning 350 tons of shale a week; that is a snapshot reported at the time, not a count of everyone who lived or worked at Joadja.^[9][11]

The steep railway incline was essential to moving shale out of the valley. The Powerhouse Museum describes trucks being hauled to the upper railway by a steam-powered winch, after which locomotives carried them toward Mittagong. Residents could also ride in the trucks at their own risk. In an account quoted by the museum, a former resident remembered carrying a seat and cushion for the journey; her recollection brings the practical challenges of village life into view.^[14]

The route to Mittagong is part of that story. The National Parks plan records the Joadja Ridge Trail as an early route for transporting shale oil, connecting the valley with Wombeyan Caves Road. It also connected settlers with High Range and Wangenderry. The plan distinguishes that historical association from surviving physical evidence: it records no known trace proving the trail’s early use. The industrial site and the adjoining nature reserve are separate places, with different access arrangements.^[10]

Joadja Nature Reserve was established beside the historic mining landscape in 2001.^[21]

Village life and later years

The village was more than its works. Council’s 1991 heritage inventory identified the school, School of Arts, boarding house, post office, cemetery and rows of workers’ housing among the complex’s components. Carrington Row and Stringybark Row offer starting points for researching the people and households behind the industrial remains. The State Library holds an early photograph of the shale-oil works by August Tronier, catalogued with an approximate date of 1870-1880.^[12]

The Council study reports that the company continued selling fruit after mining ceased and that the property was sold in 1911. The settlement’s story did not end in a single moment: the buildings, industrial remains and landscape have since been subject to change, conservation and research. Leonie Knapman’s Joadja Creek: The Shale Oil Town and Its People 1870-1911 is a useful further lead for family and community history.^[12]

The Joadja mining and refining site was entered on the NSW State Heritage Register in November 1999. The Society has continued to record its history: a 2014 newsletter noted conservation work at Carrington Row, and its 2025 tribute to Leonie Knapman recalled her books and the Back to Joadja weekends she organised.^{[16][17][18][19]}
