The iconic Sydney Opera House is seeking an estimated A$600 million (£300 million) “for what it says are much-needed renovations. The backstage equipment is in a state of dilapidation, and the orchestra pit is so small and acoustically compromised that players have to work in rotas to safeguard their hearing. The stage is so narrow that stage hands have to wait in the wings to catch the ballet dancers as they hurtle off stage.” (With video tour.)
