Chinese student Yang Chen, who went missing on Wednesday while walking with a friend in the Tallebudgera Valley, spent five nights sheltering in caves before being found by water police near Gorge Falls on Monday morning. Sgt Mitch Gray from Gold Coast water police said Chen was able to keep her hydration up during her ordeal by filling a discarded two-litre milk carton each day. Gray said police were getting increasingly concerned, especially with creeks in the region flooding. The 26-year-old Bond University student and her friend became separated trying to climb over boulders. After her ordeal, she contacted her parents in China, Bond University vice chancellor Tim Brailsford said. 'Yang and I phoned her parents in China who were ecstatic with the news, and overwhelmed with gratitude,' Brailsford said in a statement on Tuesday
