O'Meara first played hurling at juvenile and underage levels with the Kilruane MacDonaghs.[2] After winning four consecutive Tipperary U21AHC titles, he spent 20 seasons as a member of the club's senior team and is one of only a handful of players to have won seven North Tipperary SHC titles between 1977 and 1990 when he captained the team. O'Meara was at centre-back when Kilruane MacDonaghs won the All-Ireland Club Championship title in 1986, having earlier won four Tipperary SHC titles.[3][4]
O'Meara first appeared on the inter-county scene during a two-year tenure with the Tipperary minor hurling team. He also spent two seasons with the under-21 team, however, his underage career ended without success. O'Meara's performances at club level earned his inclusion on the senior team for the 1977 Munster SHC campaign.[5]
