The opening game for the New South Wales Blues saw
Todd Carney,
James Tamou,
Tony Williams and
Jamie Buhrer make their debuts, with all either having previous international representative or grand final experience.
Michael Jennings was the first Origin player in 29 years to be selected to the squad after playing in the reserve grades, where he was dropped from the
Penrith Panthers for one game due to poor off-field discipline. Jamie Buhrer from the
Manly Sea Eagles was generally the shock selection in the squad, only playing for
City Origin earlier in the year as his sole representative honour and was yet to play 50 games for his club, but was selected due to his big game experience, having played in Manly's winning
2011 NRL Grand Final team, and his high utility value to replace their recognised utility in
Kurt Gidley who was unable to play in the 2012 series to due a season-long injury. Only 9 of the selected 17 players were incumbent from Game Three in 2011. Queensland's selected side for the first game was largely unchanged from the 2011 series, with only four changes made. Their only debutant was
Matt Gillett from the
Brisbane Broncos to play a utility role from the bench. It was
hooker Cameron Smith's first match and series as the permanent captain for his state, having previously filled in for the role only in
Darren Lockyer's absence.
1st half New South Wales held most of the momentum early in the match, and scored first through winger
Akuila Uate in the sixth minute of the match, who recovered a
bomb kick and scored in the corner;
Todd Carney missed the conversion and New South Wales led 4–0. In the twenty-first minute, a brawl erupted; Blues centre
Michael Jennings, who ran some distance to leap into the brawl and punch
Brent Tate in the head, was sent to the
sin bin for ten minutes. The Maroons scored shortly afterwards, with winger
Darius Boyd touching down in the corner and
Johnathan Thurston converting to give Queensland a 6–4 lead. Boyd scored again in the thirty-eighth minute, and another successful conversion from Thurston gave Queensland a 12–4 lead at halftime.
2nd half New South Wales added points early in the second half, with Jennings scoring a try from a
bomb kick; Carney's successful conversion brought the score to 12–10. New South Wales had most of the attack during the second half, but Queensland was able to defend its goal-line and prevent the Blues from scoring; and in the fifty-second minute, Carney narrowly missed a long-range penalty goal attempt which would have levelled the scores at twelve apiece, but after seventy minutes, Queensland still led 12–10. The decision to award the try to Inglis was highly controversial. Blues captain
Paul Gallen argued vehemently with the referee onfield following the decision, although was more circumspect after the match. Inglis' controversial try saw him pass
Dale Shearer to become the all-time leading try scorer in State of Origin football. Michael Jennings received a one-match suspension for the punch for which he was sin-binned during the match. It was Queensland's fourth Game One victory in a row, the first time either team had achieved the feat. After the controversial Inglis try call, and others during the game, New South Wales coach
Ricky Stuart asked his players not to give interviews to media in the lead-up to Game II, although the ban was lifted after two days. The decision was officially endorsed by referees' coach
Bill Harrigan the following day. == Game II ==
