Some 30 students from the third and fourth-year classes at the University of Sydney’s School of Veterinary Science bared all to raise money for charity the Black Dog Institute.

Posing for the calendar has become something of a rite of passage for students at the school, and it’s a cause that’s especially important for vets, said organiser Lucy Fuchter, 23. “As soon-to-be veterinarians and animals scientists, we are entering a workforce in which the suicide rate is four times that of the national average,” she said. “So it is a cause close to our hearts.

“The Black Dog Institute is an organisation dedicated to understanding, preventing and treating mental illness. “With one in five people battling mental illness at some point in their lives, we hope that supporting the institute will assist their endeavours in helping so many.”
