The Sydney Opera House was expected to be completed in 1963. A scaled-down version opened in 1973, a decade later. The original cost was estimated at $7 million, but its delayed completion led to a cost of $102 million.
Wauchope, New South Wales
Wauchope's economy was traditionally based on the timber industry. At different stages in its history, more timber was transported out of Wauchope than out of any other town in Australia (via Wauchope railway station). Timber from Wauchope was used in the construction of the Sydney Opera House.
