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 Symphony Orchestra
Sir Eugene Goossens was succeeded by Nikolai Malko, Dean Dixon, Moshe Atzmon and Willem van Otterloo. Under van Otterloo, the orchestra made an eight-week European tour in 1974 which culminated in two concerts in Amsterdam and The Hague. Also under van Otterloo, the orchestra established the Concert Hall of the Sydney Opera House as its home base for most of its concerts.
