Norsworthy, a rover, began his career in the South Australian National Football League (SANFL) in 1969 with Central District. He won their 'best and fairest' award in 1975 and in the same year represented South Australia in interstate matches against Victoria and Tasmania. After another 'best and fairest' the following season he crossed to Melbourne but had little success. He returned to Central District once his Melbourne stint was over and retired after playing 158 SANFL games.
