At the cricket in Perth last night, noticed one hanging around above the stadium for a little while. Aside from the proximity to the heliport at Crown Towers, one of the basic rules I thought was that you don't fly over sporting events/stadiums like that lest you lose control and it drops on the unfortunate chaps below. Maybe I'm judging too quick and it was a licensed operation, but it wouldn't surprise me if it wasn't - getting that cool shot of a stadium at night overrules anything else. Given it could be launched from anywhere in a 2km+ radius of the place, all the police around the stadium are pretty powerless to do anything about it.
