FIVE Hongkong children who have had life-saving liver transplants in Australia met for the first time last night to celebrate their new lease of life. And their parents have announced they will form a support group to share their experiences and the problems of raising their children. Among the five girls was three-year-old Lau Fu-in, whose operation was paid for with a $2 million donation from South China Morning Post readers. Fu-in received a liver from an unknown donor early last year in a 10-hour operation at the Royal Children's Hospital in Brisbane. Fu-in, who will turn four next month, said: ''We can play together. I am happy to see other children.'' The toddler read out the names of the four children, all of whom received their new livers in the Brisbane hospital. The party was held at the home of the oldest, and first Hongkong child to receive a liver transplant in Australia, Diana Lee Hoi-yan. Now 14, Diana said: ''They are all very cute and smart. But they are a little bit naughty.'' Diana said she always soothed the other four, aged between two and three, and was happy to be their ''eldest sister''. Diana's mother, Mrs Pearl Li Yang Yu-shin, said a regular gathering would help to alleviate the pressure of looking after their children who require regular check-ups and must take anti-rejection drugs. ''We are in the same situation,'' she said. ''We are just like a family.'' Mrs Li spent more than 10 months in Brisbane with her daughter for the operation in 1991. The five had their operations between late 1991 and last year. They were sent to Brisbane for the operations because local surgeons found it difficult to find donors.
