About 2,500 volunteers stood naked in the early morning light at Bondi Beach in Sydney, Australia, to take part in an artwork designed to raise awareness about skin cancer.
Their photo collection is the latest project from American photographer Spencer Tunick and aims to encourage Australians to get regular skin checks.
Australian legislation has been changed to allow public nudity on beaches.
According to the World Cancer Research Fund, Australia is the country most affected by skin cancer.
Starting at 3:30am local time, volunteers gathered on the beach to take part in the installation, which was created in partnership with the Skin Check Champions charity during Skin Cancer Awareness Week.
“We have an opportunity to raise awareness about skin checkups, and I’m honored to come here and do my art and celebrate the body and awareness of skincare,” the famed artist, Tonic, said in remarks reported by Reuters.
“I’ve spent half my life in the sun,” Bruce Fisher, 77, who attended the event, told AFP.
“I guess it’s a good cause, and I like stripping on Bondi Beach.”
Tonic is famous for staging nude group photos in some of the world’s most famous locations.
