The performances in Sydney Opera House are visited by about a million people a year. Some of the performances are very affordable. Even if you’re not planning to attend any of the performances at the Opera, you can get a hint of what the interior of the building looks like by popping inside the foyer, where the gift shop is situated. You might get lucky and witness a free projection mapping on a large part of the roof of the building, for example on this occasion. There is, however, a regular projection show with aboriginal motives displayed on the Opera House’s eastern Bennelong sail. The show takes place every day at 8:30 pm, 9:00 pm, and 9:30 pm.
