The Newcastle Steelworks was a steel mill founded by BHP in Newcastle, New South Wales. Construction commenced in January 1913, with production starting in March 1915. The facility was officially inaugurated on 2 June 1915 by the Governor-General Ronald Munro Ferguson. Its location was deliberately selected due to its closeness to the Hunter Valley coal deposits and iron ore supplied from Whyalla.
At its height in 1981, the steelworks provided employment to approximately 11,000 individuals, ranking it among the largest employers in Australia. Operations were terminated on 30 September 1999, followed by demolition efforts beginning in 2000.
By 2022, the Department of Planning & Environment sought expressions of interest for redevelopment projects on the extensively cleaned former steelworks site.
