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.
Opera Australia
While not yet appearing with this company, Joan Sutherland, then an internationally known Australian soprano, and her husband, the conductor Richard Bonynge, helped the cause of opera in general in Australia during the 1960s. Sutherland's name was also linked to the progress of the Sydney Opera House, begun in 1957 and still undergoing a lengthy and controversial construction. By the time 'La Stupenda' appeared there in 1974, one year after the opening of the theatre, the company was a leading repertory company with a large chorus and a roster of experienced Australian principals supplemented by guest singers and conductors.
