Greg Matthews was referred to as the best ever player of New South Wales by his friend Geoff Lawson. Matthews is the holder of the wicket and appearance record of New South Wales. In the Madras tied Test in 1986-87, while his fellowmen were bothered by the heat, he played throughout the match in a sweater. The highlight of this match was that Matthews made 10 dismissals and was honored as the Man of the Match.
Matthews was selected as a hard working offspinner in the Australian team. He rose to the status of the most hip player in the country due to his determined fighting spirit, cool lingo and extravagant affectations. However, as a bowler he lacked penetration and in Tests had an average of 48. His left handed batting can be categorized as inelegant but courageous with which he scored 4 hundreds and had an average of 41 in Tests.
