Although lacking international experience many of the players winning their first caps that day went on to form the nucleus of the Wales team that beat The Original All Blacks in 1905, including Arthur Harding, Will Joseph, and fellow collier Dai "Tarw" Jones.
In a very close encounter, Osbourne scored his one and only international try on his début; Wales then won the game through a late penalty goal from John Strand-Jones.

It is unknown if Osborne would have won any further international caps as in September 1903 he signed professional terms with Huddersfield Rugby League Club, as a forward.
