Tromp made his test debut for South Africa in 1996 during the second test against New Zealand at Kings Park in Durban. He played a further three test matches in 1996, the third test against New Zealand and one test each against Argentina and France. He also played four tour matches, scoring one try for the Springboks.[4]
Conviction
In 1993, Tromp and his father were convicted of manslaughter after a labourer on their family farm died from injuries sustained in a "disciplinary" beating. The victim had allegedly stolen money from the Tromps, who tied him to a tree and took turns beating him with a fan belt. Tromp was sentenced to two years in prison but was released after six months.[5][6]
