Cameron Smith played a starring role before Melbourne Storm survived a second-half fightback to beat Penrith Panthers 26-20 in a pulsating NRL Grand Final.
Hooker Smith - potentially playing his final game - scored a try and also kicked 10 points to help Melbourne overcome the team who finished above them in the table.
Penrith had triumphed when the teams met in the regular season on their way to being crowned minor premiers, yet a first title since 2003 proved out of their reach as they were made to pay for costly errors at ANZ Stadium in Sydney on Sunday.
Melbourne capitalised in clinical fashion, opening up a commanding 22-0 lead at the break that, despite the Panthers trying to claw their way back in the closing stages, set up the victory.
Justin Olam was awarded a penalty try after the ball was kicked out of his grasp in the process of trying to ground it over the line, while the Panthers' poor discipline allowed Smith to kick his team into a double-digit advantage.
After Suliasi Vunivalu intercepted a looping Nathan Cleary pass and raced clear to score a second try, Smith collected a loose ball and darted over from close range just prior to the interval.
When man of the match Ryan Papenhuyzen broke free from inside Melbourne's own half to cross early in the second half, the game appeared to over as a contest.
However, having seen two tries chalked off in the first half, Penrith finally opened their account when Brian To'o finished in the corner, the score awarded despite suggestions of obstruction in the build-up.
Stephen Crichton added another try and when Josh Mansour raced through on the Panthers' left less than four minutes later, a miraculous comeback suddenly seemed a serious possibility.
Yet the deficit was too much with the clock against them and Melbourne held on, even with Jahrome Hughes and Brandon Smith finishing the game in the sin-bin.
Cleary barged through as the Storm's 11 men were breached again in the final minute, though it was a mere consolation effort as Craig Bellamy's side sealed a fourth premiership in the NRL era.
