A western Sydney man has changed five lives for the better, after becoming the first foreign organ donor in a major southwestern Chinese city.

Doctors and medical staff bowed deeply at the bed of Emu Heights man Phillip Hancock last month, when he donated his two corneas, both kidneys and his liver to five people in Chongqing.

The 26-year-old died in a city hospital on May 9, following complications related to diabetes.

Mr Hancock had long advocated for organ donation and so at the time of his death, his parents made enquiries to fulfil his wish.
