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.
History of Australia since 1945
The iconic Sydney Opera House finally opened in 1973 after numerous delays. In the same year, Patrick White became the first Australian to win a Nobel Prize for Literature. Australian History had begun to appear on school curriculums by the 1970s and from the early 1970s, the Australian cinema began to produce the Australian New Wave of feature films based on uniquely Australian themes. Film funding began under the Gorton government, but it was the South Australian Film Corporation that took the lead in supporting filmmaking and among their great successes were quintessential Australian films "Sunday Too Far Away" (1974) "Picnic at Hanging Rock" (1975), "Breaker Morant" (1980) and "Gallipoli" (1981). The national funding body, the Australian Film Commission, was established in 1975.
