Ayers Rock is considered sacred by the aborigines; the government caters to them by forbidding its use in commercial photography without permission.
Of course, the tour guide people also make the “it’s sacred, please respect their wishes and don’t climb” speech. (Then they drop you off at the climb entrance) Women are forbidden to climb too. However, it’s a personal choice, and it gets pretty crowded up there, so the number of people, male and female, who give a fig about someone else’s peculiar religious landscape fetish seems pretty limited. I’ve also climbed St Pauls and the Vatican, and the cathedrals in Milan and Florence, so I guess I’m equal-opportunity sacred-spot climber.
I’ve never heard about anyone being told not to photograph Sydney Hah-bah. I assume like most big cities, there are requirements for permits for people who want to block the area with a significant amount of photography equipment?
Many museums, churches, etc. used to be “photography but please no flash”. However, with the ubiquity of modern flash digital cameras, and people unclear on the concept of disabling their flash (and possibly a desire to enhance museum store sales) have banned photography entirely.
Enforcement varies. I recall the area around the Mona Lisa (IIRC that wing) was “no photography strictly enforced”. One day that was true, the next it seems like Inspector Clouseau was in chage. A huge collection of gawkers had cameras out and were snapping away at the Mona until a few too many flashes went off, then one guard said something to the other and they tried to stop everyone.
Similarly, once (about 10 years ago) in the Sistine Chapel the guards were vigilant about no photos. The lighting was poor enough that it ook 1/5sec to get a good exposure; I had to sit on the bench along the wall, and hide the camera braced beside me on the bench to get a good photo. We were back a few hours later and people were snapping and one guy even video-taping the scene; after about two or 3 flashes, the guards waded into the crowd and started telling people to put away their cameras; the rest of the Vatican museum had no restrictions other than flash, same with most churches and museums in Italy.
In the Dalai Lama’s Palace, photography was forbidden (and the lighting sucked). I decided it was not a good idea to tick off Chinese security, possibly get tossed out prematurely or arrested or lose my equipment (they let me carry the camera in). In other monasteries in Tibet, they often have a small fee (15Y = about $2.50) to photograph in some rooms. I read that the entrace ticket fees go to the government cultural agencies and photo fees and donations go to the monks.
I do recall many many years ago I was in the Toronto Art Gallery and a guard pratically dived in front of me to stop me from taking a picture. Anything else was fair game, but apparently this one interesting renaissance portrait was a loan from a private individual and they did not want any pictures.
