Tin City is the local name for a group of huts behind the frontal dune on Stockton Bight, in the Worimi Conservation Lands between Newcastle and Port Stephens, New South Wales, on Worimi country. In 2015 there were 11, all single storey and clad in corrugated iron, with gable or skillion roofs. Most were built in the 1970s and 1980s; the oldest still standing that year dated from December 1970 and the youngest from 1992.
The huts at Tin City are linked to the history of recreational fishing along the beach, and in 2015 they were still in use, with fishing popular among their owners. In January 2014 Tin City had no power, no water and no sewerage. Since the 1970s and 1980s some huts have been demolished or destroyed, and others rebuilt or moved within Tin City, modernised and in some cases expanded.
The mobile dunes of Stockton Bight are the largest continuous mobile sand mass in New South Wales. They reach up to 40 metres above sea level and migrate inland at about 4 metres a year on average. Tin City is affected by sand drift, and depending on the weather the occupants protect the huts from erosion or from inundation by windblown sand.
Tin City was assessed in 2006 as having local heritage significance. On 1 February 2007 the land was returned to Worimi ownership: the Worimi Local Aboriginal Land Council holds the title on behalf of the registered Worimi owners and leases it back to the NSW Government, and the 4029 hectares of the Worimi Conservation Lands are reserved as Worimi National Park, Worimi State Conservation Area and Worimi Regional Park. The Plan of Management for the Lands, adopted on 1 September 2015, directs that a licence be established for the hut sites at Tin City, prohibiting new huts, the expansion or relocation of any hut, and permanent residency.
