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.
My Fair Lady
The Gordon Frost Organisation, together with Opera Australia, presented a production at the Sydney Opera House from August 30 to November 5, 2016. It was directed by Dame Julie Andrews and featured the set and costume designs of the original 1956 production by Oliver Smith and Cecil Beaton. The production sold more tickets than any other in the history of the Sydney Opera House. The show is then planned to tour to Brisbane from March 12 and Melbourne from May 11. The show's opening run in Sydney was so successful that in November 2016, ticket pre-sales were released for a re-run in Sydney, with the extra shows scheduled between August 24 and September 10, 2017, at the Capitol Theatre.
