Series matches

Queensland have won 24 series. NSW have won 16. On 2 occasion have both teams drawn a series (1999, 2002). (As of 2023)

One off matches

The matches in 1980 and 1981 were one off experimental matches after New South Wales had already won the interstate series in both years. Both games count toward official statistics, but are not considered series.

After Queensland had won the 1987 State of Origin series 2–1, a further game was played in Long Beach, California to showcase rugby league to the American public. On 15 July 2003 the Australian Rugby League announced that this game was to be classified as an "official match" and that the match would count towards the players' individual statistics and overall match win–loss–draw records. However, the match does not count towards the series win–loss–draw record and the 1987 series still remains a 2–1 win to Queensland.

Super League

New South Wales and Queensland played two matches against each other under State of Origin selection rules using players from the Super League (Australia) competition. These matches were not sanctioned by the Australian Rugby League and are not counted as official State of Origin series matches. The Tri-series also included both sides playing a game against New Zealand.
