Cometh the hour, cometh the Munster

Queensland legend Billy Slater is keenly anticipating what Cameron Munster can deliver for the Maroons in Wednesday night's State of Origin decider.

Munster played at five-eighth for the first two games of the 2019 series, but will revert to his preferred full-back position at ANZ Stadium with star No.1 Kalyn Ponga sidelined through injury.

The Melbourne Storm star wore the No.1 jersey for his club side at stages earlier in his career and Slater is looking forward to see what he can deliver against NSW in the Origin decider.

"I am really excited to see Cameron play fullback," Slater said.

"It is his preferred position and his most dangerous position.

"I think he will take to it like duck to water as he’s that sort of guy that nothing fazes him.

"He will be looking forward to the challenge and he will get the ball in his hands a lot more.

"He will be a lot more dangerous, so it is only good for Queensland."

Just how Munster performs at full-back might the one ace up Maroons coach Kevin Walters' sleeve, with Queensland hit with a late injury crisis that has seen veteran utility Matt Gillett ruled out of the deciding game.

Corey Norman moves into the halves to partner skipper Dale Cherry-Evans, while Walters is still deciding who will replace Gillett in the second row.

Slater believes Queensland can still win on Wednesday night, but admits everything must fall into place if they are to do so.

"From my time in camp earlier this week Corey Norman was really vocal," Slater noted.

"He was a leader on the left edge already and that is great signs.

"He strikes me as a player that won’t be overawed by the situation and the atmosphere and the situation.

"If Queensland can do the little things really well, which we didn’t do in game two, it will give us a chance to show the talent we have got.

"If we don’t do that we won’t get a chance."
