The size of the interior of the building was scaled down appreciably by a team of architects
whose job it was to finish construction within a restricted budget. Rehearsal rooms and
other facilities for the various theatres within the complex were either made considerably
smaller or cut out altogether, and some artists have complained bitterly about them ever
since. But despite the controversy that surrounded its birth, the Opera House has risen
above the petty squabbling and is now rightfully hailed as a modern architectural
masterpiece. The Queen officially opened the building in 1975 and since then, within its
curved and twisted walls, audiences of all nationalities have been quick to acclaim the
many world-class performances of stars from the Australian opera, ballet and theatre.
