Hundreds of Melburnians will go starkers in the cold as they participate in photographer Spencer Tunick's mass nude photo shoot.
The American artist has said he will use 500 participants covered in nothing but body paint for his Sunday afternoon installation as part of the Provocare Festival in Melbourne's Chapel Street area.
A second nude installation will take place on Monday atop a Woolworths supermarket car park.
Tunick has reassured participants he will work quickly in the chilly weather with a maximum expected temperature of 13 degrees Celsius.
"When people are naked and it's cold, I work as if I feel like there are police behind me trying to arrest me," he said earlier in the week.
Tunick received 12,000 applications for his events at the festival but could only accept a total of 1000 because of limited space.
He has been creating nude art installations in iconic public spaces for decades but said the unpredictability of his work means his photographs might not be any good.
Michael Boland, who is taking part in Sunday's photo shoot, says it's about "facing your fears and just doing it".
"This is just getting naked on a mass scale and being a part of history. I am really excited, nervous," he told the Seven Network's Sunrise program.
