With the Blues down one nil in the series, they must win to keep the it alive and send it to a deciding game, which will be played in Brisbane on July 8.

Charli Pettit, who works at Sportsmans Warehouse in Dubbo, was proudly wearing her blues jumper on Tuesday, and is confident NSW will bounce back and get the win.

"I am confident we will get up," Charli said.

"We have got a lot to prove after copping it for eight years, but I think the confidence the players would have got after winning last year will help them get the win."

With the Maroons going into the clash comfortable favourites, the Blues will be up against it to improve on their performance in the first game, which they lost 11-10.

One person who is hoping the Maroons clinch the series is Bailey Edmunds, who is confident the skills of Greg Inglis, Billy Slater and Johnathan Thurston will be too good for the Blues.

"I'm very confident as we have the best side," Bailey said.

"I think this can be the start of 10 series in a row.

"In the backs we have the Blues covered and the halves are classier."

While confident of the win, Bailey is tipping a tight contest with the Maroons to get up by one point, while Charlie is tipping the Blues by 24 to 18.
