About 5,200 naked people embraced on the steps of Sydney Opera House for a photoshoot by Spencer Tunick.
Tunick, who is known for his nude group photos in public spaces, posed participants for more than an hour.
"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 in this morning's stunt for gay rights.
"I'll never get a chance to do this again, it's not worth being inhibited," Rush said.
"It doesn't feel sexual, it just feels tribal, a gathering of humanity."
