Te Maire Martin is a genuine half - and would offer a lot more on attack - but has barely played since his shoulder injury in May. Last week was his first taste of test football, and there is no doubt the Kangaroos would relentlessly target the youngster down one edge.
Other such as Gerard Beale, Jordan Kahu and Lewis Brown could also fill the role (in theory) but would be longshots and in the case of Kahu and Brown would weaken other positions.
Though it is not an ideal situation, there is some upside to Harris' lining up in the halves. He will offer a considerable running threat - to test the likes of Cooper Cronk on defence - and Harris will also provide some extra defensive protection on the edge of the ruck.
But it will also be a test for the Kiwis, who will have to defy conventional league logic. It will heap even more pressure on halfback Shaun Johnson, who the Kangaroos will surely target as the sole playmaker.
It also removes a kicking option, as Leuluai was an effective kicker, especially from close range. Expect Jordan Kahu to take on some more responsibility in that area, as well as hooker Issac Luke.
