About Bill Harrigan
Bill Harrigan is an Australian former rugby league football referee, and former head of refereeing for the National Rugby League. Unusually for a sports official, in his long career he was accorded the same profile as some of the top players he refereed. A policeman off-field before he resigned to concentrate on rugby league, he is widely recognised as one of Australia's greatest sports umpires. He retired with the record for most State of Origin matches officiated. Harrigan refereed his first game in 1977.
