On 28 March 2007, Cain and several members of the Australian figure skating team were in a small boat in Sydney Harbour near the Harbor Bridge when it collided with a ferry. Cain lost her leg in the accident, which has become known as the Sydney Harbour Bridge Ferry Disaster. However, her life was saved by her son, who jumped into the water and held her until rescuers could arrive. She has since returned to coaching. Due to her accident, she wears a prosthetic leg.
