Recruited from Camberwell Juniors in 1950, O’Mahony won the Reserves Best & Fairest in his first year with the Hawks. Graduating to the senior side in 1951 he was an instant star playing initially as a half back then making his name in the centre where he proved to be an elusive and clever performer who marked and kicked well to position. He suffered a punctured lung early in 1957 and ended in Hospital for 3 months missing Hawthorn’s first ever finals appearance. A gifted player, he was an unselfish footballer and his creative team play was reflected in him coming second in the Best and Fairest in 1955 then third in 1956.
He later became assistant coach for two stints and the Hawk’s Chairman of Selectors. O’Mahony’s deep passion of the fortunes of the Club saw his step up in time of need and play an important role as treasurer to Operation Payback led by formed Captain Don Scott.
In 2003 he was invited to be a member of the selection panel for the Club’s Hall of Fame and in 2008 became the Chairperson for the newly formed Life Members Committee.
Always the faithful Club member, O’Mahony as been a financial member of the Past Players since he retired in 1960, has attended on a regular basis, Graham Arthur’s famed Hawka’s Lunches since the 1980s and had been a regular attendee watching training with his fellow teammates, John Kennedy Snr and the late Roy Simmonds. His grandson Jarryd Blair plays for the Collingwood Football Club and was a member of their 2010 Premiership.
