Planning fallacy
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.
Sydney Chamber Opera
Sydney Chamber Opera is an opera company based in Sydney, Australia. It is a resident company at Carriageworks. The company was founded in 2010 by Louis Garrick and Jack Symonds. Its first production was in February 2011 and has since produced between two and four twentieth and twenty-first century chamber operas each year. Its repertoire typically consists of world premieres of Australian operas and recent international works receiving their Australian premieres, including stagings of song cycles or non-traditional stage works.
