Between the 1891 and 1892 seasons, Clauss was invited to join the British Isles team on their tour of South Africa. This was the first official overseas tour for the British Isles team, and took in three Test Matches against the South Africa national team. Clauss played in the first five matches of the tour, scoring tries in the first four games. Although Clauss was not in the team for the games against Port Elizabeth and Eastern Province he was brought in at his preferred three-quarters position along with tour captain Bill Maclagan and Randolph Aston. The British Isles team won the game 4–0, but Clauss missed the next five games of the tour, only returning three weeks later for the matches against Johannesburg, Transvaal and Cape Colony. Clauss finished his tour with the wins against South Africa in the Second and Third Tests, and scored a try in the encounter with Cape Colony between the final Tests.
