Queensland survived a late rally from New South Wales to claim a tense 16-10 victory in this year's State of Origin opener in Sydney.
New South Wales went into Origin I having won three of the last four series, and Jack Wighton crashed over in the 14th minute at Accor Stadium to give them a 4-0 lead.
But the Blues could not build on that advantage and the Maroons overturned it in the 34th minute when Dane Gagai pounced on Selwyn Cobbo's grubber kick and Valentine Holmes added the extras.
Junior Paulo looked to have quickly restored the Blues' lead, only for Cameron Murray to be penalised for obstruction and Queensland took control after the restart.
Daly Cherry-Evans side-stepped his way over as first receiver from the scrum eight minutes into the second half and Kalyn Ponga fed Holmes for Queensland's third try five minutes later.
Murray gave New South Wales hope nine minutes from time, but Queensland held on with a great defensive effort led by Man of the Match Cameron Munster, who helped secure the win for former Melbourne Storm and Maroons team-mate Billy Slater in his first Origin game as head coach.
