Rea first appeared in the World Championship in 1949, when he lost 18–17 to Conrad Stanbury in the second qualifying round. He didn't enter again until 1952 when he won two matches before losing to Fred Davis in the semi-final. He lost to John Pulman in the 1953 championship and again in the 1954 championships, losing this latter match just 31–30. He lost to Pulman again in 1956, separated by a loss to Fred Davis in a 1955 semi-final after beating Harry Stokes. By 1957 interest in snooker was ebbing and there just four entries for the World Title. Rea easily defeated Kingsley Kennerley in the semi-final 25–12 and ran John Pulman close before losing 39–34.
