Thousands strip for Sydney photos
About 5,200 naked people embraced each other on the steps of Sydney's Opera House for a photo shoot by Spencer Tunick.
Tunick, who is known for his nude group photos in public spaces, posed participants for more than an hour in a variety of positions.
"It was difficult to get the straight participants to embrace the gay participants and vice versa," Tunick said. "So I was very happy that that last set up finally got done and everyone came together (in a) united, friendly kiss, a loving kiss in front of this great structure."
Nineteen-year-old student Art Rush said he was thrilled to participate.
"I'll never get a chance to do this again, it's not worth being inhibited," Mr Rush said. "It doesn't feel sexual, it just feels tribal, a gathering of humanity."
