Sneddon played rugby league for Grafton in the NSW Country competition before being spotted by Balmain scouts and was signed by the club.
Balmain were unable to score any further points and lost the grand final in front of 30,000 fans at the Sydney Sports Ground.
The following year, Balmain reached the preliminary final against St George but lost the match to the eventual premiers 18-7.
Sneddon only made 2 appearances for South Sydney and missed out on playing in the club's grand final victory over Western Suburbs.
Sneddon did not return to the Souths team in 1951 after he suffered a serious knee injury and had to retire prematurely.
