On the eastern shoreline of Sydney is Bondi Beach. Here are my photos.
The pavilion where they filmed the scene in Cosi where they went to see Nick's play, is practically on the beach. Unfortunately I didn't take a photo, but I thought I'd mention this tidbit and give you some views of the beach. At the time I had no idea the amphitheater was inside the pavilion, so I didn't take a photo. Apologies.
Enjoy the beach.
