South Sydney and Roosters became the first clubs to play 200 matches against each other. The Sydney Roosters 36–10 victory put the ledger at 105 games won by South Sydney, 90 by the Roosters (Eastern Suburbs) and 5 drawn. To celebrate their rivalry, South Sydney and the Sydney Roosters play for the Ron Coote Cup annually. St George Dragons and St George Illawarra Dragons – The long-standing rivalry against St. George results in the annual Charity Shield match, originally played against the original St. George Dragons and now (since the joint venture formed with Illawarra Steelers) played against the current team, St. George Illawarra. South Sydney and St. George have met several times in grand finals prior to the joint-venture and being the north-eastern neighbours of St. George, had many fierce encounters. In 2001, South Sydney chairman and club legend George Piggins said there would be no chance of the Charity Shield being revived if Souths were to be included back into the NRL saying "The Dragons: They sold us out".

In the 2013 preliminary final, Souths were looking to reach their first grand final since 1971 when they faced off against Manly. Souths lead the match 14-0 early on but were eventually defeated by Manly 30–20. In the 2021 NRL season, South Sydney and Manly once again met in the preliminary final but on this occasion South Sydney ran out comfortable winners to reach the 2021 NRL Grand Final.
