The fact Australia's forwards have been found wanting has restricted their options and I am sure Sheens will be challenging his forwards to step up and provide the grunt needed to put them on the front foot.
The onus will fall on props Aaron Woods and Josh Papalii to aim up and match the Kiwis in the middle while the likes of back-rowers Corey Parker and Sam Thaiday also need to produce big performances.
Sheens will know they need to vary their play a little bit this weekend and come up with a game plan that suits their style of play.
Having one referee makes it easier for teams to slow down the play of the ball and dictate the pace of the game so I believe the Kangaroos will look to move the ball to avoid getting locked into a forward battle in the middle of the park.
If they can raise the tempo of the match by spreading the ball quickly to the edges and play with some variation around the ruck, they could nullify the Kiwis' size advantage in the forwards and avoid the two and three-man tackles.
The Kangaroos are also sure to come up with at least one set-play that will target the Kiwis out wide, where they will look to isolate defenders against their quick, elusive and powerful backs, such as Dylan Walker, Michael Jennings, Sione Mata'utia and Greg Inglis.
The inclusion of Robbie Farah on the interchange bench comes as a surprise as he has not played since the first-up loss in Brisbane and has no obvious role in the side.
Sheens might see Farah as a tempo-changer but it is difficult to see Smith leaving the field in such an important match and it seems unlikely he would want to disrupt the halves pairing of Cooper Cronk and Daly Cherry-Evans.
For the Kiwis, they have a tremendous opportunity to win the Four Nations with a clean sweep and beat the Kangaroos twice in quick succession, which would be a special feat. It's also an opportunity for the New Zealand players to fulfil their potential and make their mark as a group. They have a good balance of experienced campaigners and a younger crop of stars coming through and the close bond within the squad is clear to see in the way they are gelling and playing for each other.
However, their memorable victory in Brisbane is now long gone and will mean nothing if they lose tomorrow night.
Despite all the improvements and promise in their play over the past three weeks, nothing less than another victory is acceptable.
