Australia's Olympic delegation bathed in pride on Sunday, as the country hailed a record Winter Games medal haul for its team and an unlikely hero in skeleton racer Jackie Narracott.

Narracott's surprise silver in women's skeleton on Saturday pushed Australia to a record fourth medal in Beijing, following gold for freestyle skier Jakara Anthony, snowboarder Scotty James' silver and bronze for women's snowboarder Tess Coady.

"It is a fantastic morning," Australia chef de mission Geoff Lipshut told reporters in Zhangjiakou, China, on Sunday. "It was (an) absolute thrill last night, it was history-making."
