Maroons five-eighth Tom Dearden has revealed the role injured star Cameron Munster played in helping him prepare for a dominant Origin return. 

The Cowboys No.6 likely would have been watching Wednesday night's State of Origin opener from the sidelines if not for a serious groin injury suffered by Munster during Magic Round. 

Instead, Dearden helped dismantle a 12-man Blues after Joseph-Aukuso Sua'ali'i was sent off early in Queensland's 38-10 win.

Munster was quick to congratulate his replacement in the sheds post-game and Dearden revealed the pair have formed a close bond in previous Maroons camps.

"I've been lucky I've been involved in camps for the last couple of years," Dearden told NRL.com. "To sit back and watch how [Munster] and [Daly Cherry-Evans] operate, you learn so much watching them. 

"He's been awesome, Munster, he's a great role model and a great player for myself."

There was plenty of speculation about who would receive the call up to wear the No.6 jersey throughout the Origin series after Munster's injury. 

Brisbane youngster Ezra Mam starred for the Broncos during last year's grand final and has taken his game to another level this season. A future Queensland star, he was a member of the extended squad before Game One and it shapes as a matter of when, not if, his name will be called. 

From the field: Dearden

Dearden was considered the steady hand, having delivered in his only prior Origin match in 2022.

The 23-year-old repaid the faith with interest, finishing with 131 running metres, one try assist, five tackle breaks and a line break.

While replacing Munster is no easy feat, Dearden knew he had a responsibility to his teammates and supporters to deliver a victory. 

"Every chance I get to wear the Maroons jersey, it's always a privilege," he said. "It's something I'll never take for granted.

"You're playing for more than just yourself, that's the mentality we have. There's 5.5 million Queenslanders that are watching us. With that comes the pressure of making sure you put the best foot forward and do your job for Queensland."
