Queensland have pulled off a famous victory over New South Wales in the State of Origin decider at Accord Stadium on Wednesday night.

Coming into the match as heavy underdogs, the Maroons stunned the shellshocked hosts with a dominant first half before keeping the Blues at bay in a 24-12 result.

The victory sealed an incredible series triumph for the Maroons after they were given no hope following the heavy loss in Game I.

The Maroons piled on 20 points in the first half with three tries and a penalty goal, while keeping the Blues scoreless in the process.

New South Wales flipped the script in the second half, but they didn’t manage their first points until the 57th minute.

It was a case of too little, too late as the Maroons held firm on an emotional night for skipper Cameron Munster.

Munster heroically led his side, just days after the sudden death of his father Steven over the weekend.

“It’s a brave and courageous effort for him to be out there,” coach Billy Slater said during the first half.

Valentine Holmes opened the scoring with an early penalty goal.

Xavier Coates crossed first on the sideline despite a hint of the final pass from Gehamat Shibasaki going forward.

Queensland dominated the opening stages and got their reward with another try midway through the first half as the Blues were caught napping.

Robert Toia looked certain to be dragged out of bounds, but he cleverly kept the ball alive and Hamiso Tabuai-Fidow reacted first to break the line and set up Tom Dearden for the easiest of tries.

“The New South Wales players stopped, they thought it was a lost ball,” Mat Thompson said in commentary.

“You just can’t stop. Not at this level. You stop for a moment, for a split second and you get penalised by a play like that,” Andrew Johns added.

Things went from bad to worse for NSW in the final minutes of the first half when they conceded another poor try.

Harry Grant was able to muscle his way over the line, beating three Blues defenders in the process.

That put the underdogs up 20-0 at half-time.

“I think everyone in the grandstand are shellshocked,” Queensland great Cameron Smith said in commentary.

New South Wales came out firing in the second half, but couldn’t translate their dominance into points.

That was until Stephen Crichton finally scored the Blues’ first points of the night when he crossed in the corner. Zac Lomax slotted the tough sideline conversion to reduce the margin to 14 points.

Despite the Blues continuing to push, the Maroons held firm. It wasn’t until the 68th minute when they made their first handling error of the match.

As time ticked down, Dearden rubber-stamped his outstanding performance with another try to seal the incredible win.

Brian To’o added a consolation try in the final minute to equal the record for most tries in a series with five.
