Two tin sheds were put up on the Stockton Bight dunes in the late nineteenth century to hold provisions for sailors shipwrecked on the beach. During the Great Depression a group of squatters built a series of shacks around them. The settlement that grew became Tin City, on Worimi country, in the largest mobile coastal sand mass in the Southern Hemisphere.
Eleven shacks remain. The corrugated iron and timber have been repaired and rebuilt across decades against wind, sand burial, and storm surge. The dunes around them move approximately 4 metres north a year, with slopes up to 60 degrees and crests over 30 metres high.
During the Second World War the Army demolished the shacks for a coastal camp. When the squatters came back at the end of the war, the migrating sand had buried their huts. They rebuilt with driftwood and military crates washed up on the beach.
On 1 February 2007 the Crown returned the land to the Worimi Local Aboriginal Land Council, leased it back to the NSW Government, and gazetted the dunes as Worimi National Park, Worimi State Conservation Area, and Worimi Regional Park. The Worimi Conservation Lands Plan of Management 2015 governs the shacks: no new ones, no rebuilding after destruction. Shacks pass to family or friends; they can't be sold.
