Sydney Opera House
I finally did the Opera House tour when I flew over to Sydney for a weekend from Canberra. It was a pretty good tour - the tour guide was excellent. The views from inside the building are really magnificent. Unfortunately, we couldn't take pictures of any of the actual performance rooms as there were people working in all of them at the time - their privacy regulations are such that if anyone is working in the rooms, you can't take photos.

The tour guide mentioned that they don't have to wash the tiles - rain keeps them clean. He also said that they're not white so that the structure doesn't become blinding in the sun, which makes sense.
