For the first time in its history, Bondi has been declared a nude beach

On Saturday, thousands of bodies huddled together in the early morning light to model in artist Spencer Tunick’s latest Australian installation – and his first in the name of skin

Legislation had to be changed to permit public nudity on the beach – Sydneysiders had until 10am to bare all on Bondi before risking a fine

The 2,500-strong crowd represented the approximate number of people whoof skinnationally each year. Tunick hoped the installation would encourage Australians, who top the world for mortalities to theto get regular skin checks

“Skin unites us and protects us,” he said. “I use the amazing array of body types and skin tones to create my work, so it feels perfectly appropriate to take part in this effort in that my medium is the nude human form.”
At 4am, Tunick stood on a small orange crane in the shadows, calling out demands from a megaphone. The crowd chuckled in the darkness, sheltering each other from the blistering sea wind

“Put your arms out when you’re posing and make sure you have the space of finger to finger,” he called. “Don’t getyet.”
Some wrapped towels around their bodies for warmth, others photographed the sunrise. Then, on the count of three, the crowd flung off their clothes – shirts and jumpers flying into the air in a sea of colour. They clapped and held hands and walked out to the sea, leaving discarded outfits and bags on the sand

By 5.30am the beach was awash with light, and Tunick assembled his mass of bodies into predetermined poses

“Those people that are wearing clothes, get out of the frame,” he yelled. “Don’t smile. Hands by your side. You’re too much in a line.”
With a chorus of cheers, a final, rogueman ran to meet his group. As the crowd moved to another pose, some frolicked in the sea. One man raised a woman into the air who balanced, poised like an ancient Greek statue

Tunick’s last visit to the city was in 2010, when he photographed thousands ofpeople on the steps of the Sydney Opera House for Mardi Gras

Kate Brown took part in the installation, and has admired Tunick since the mid-90s

“The Opera House was a really amazing, amazing experience,” she said. “I always said, ‘if you’re in Sydney, I’m doing it again’

“It was liberating … it was ecstatic, it was pleasurable just to be without clothing … cathartic.”
On Saturday morning, Brown met Trisha Cladera and a string of others for the first time, who were huddled on the beach at 3am

“I haven’t done it before … but I thought it was a prime spot to get your kit off,” Cladera said

“We’d never met each other before, and after our first couple of hours we took our clothes off … You’ve only got one body, so why not celebrate it?”
For Sarah Bowen, the cause was closer to home. Both her sister and father have survived melanoma

“It was freezing, but also empowering to be with so many people supporting the cause and also just being likeand seeing so many different people and shapes and sizes,” she said. “Everyone just being comfortable being. It was wonderful.”
Duncan Mathers said he was “more nervous about driving here and not getting a park”

“When everyone getsit just becomes very normal. Coming back is when it gets weird.”
By 7am, thehad wrapped up, but some lingered – some swam in the ocean, while others stretched out on towels

A group of diehards put on rave music and danced in a circle, their arms outstretched to the sun. Three hours were left before reality bit.
