A versatile player, Thomas found himself being moved between centre and wing and was chosen many times due to his ability as a utility back.

[6] Thomas also represented Cornwall and Monmouthsire at county level, and played invitational matches for the Barbarians and Crawshays.

[7] Thomas made his debut against France in 1949 in an away game at the Stade de Colombes, Paris, which Wales lost.

The selectors kept faith with Thomas and he turned out for the next four Five Nations Tournament games, which saw Wales win the Grand Slam in 1950, the first time since 1911.

In 1953 he was dropped from the squad as the selectors believed his play was becoming stale and was blamed for a bad pass in the game against England.
