Wales was unbeaten in 1908 and 1909. At the end of the 1907–08 season, in which Williams was again top try scorer for Cardiff with 13 tries, Williams was part of Arthur Harding's Anglo-Welsh team that toured the Antipodes. Although an unsuccessful tour, he played well and ended as the team's top try scorer. He then missed the start of the 1908–09 season and did not return to Cardiff until November. The club faced Australia on 28 December 1908, and handed the tourists the biggest defeat of their tour, 24–8, Williams providing two tries. Cardiff finished the season as Welsh Champions, Williams having scored 15 tries in 26 appearances, to Spiller's 16 in 27.
