The Kiwis are rank outsiders for the match on Monday, after having lost the last three trans-tasman encounters (0-16, 6-26 and 8-14) in fairly comprehensive fashion.
To add to the task, they are facing a Kangaroos side that has improved significantly with every match in this tournament, and are a few notches above what we saw in Perth last month.
"We need to put out the best 80 minutes of the tournament together on Sunday," said Kidwell. "We are playing against an Australian team that have beaten us the last few times but I have full confidence in this team, they will be prepared and committed."
When asked what gave him confidence that the Kiwis could perform, Kidwell was scant on specifics but preferred to take a holistic view.
"We have confidence in our own ability, our own style that we play," said Kidwell. "The way we have worked hard to commit to stuff, how tight our group is. That gives you confidence. It's our preparation and the spirit that's in the group."
The rookie head coach has a big decision to make later in the week, as he decides who will replace Thomas Leuluai in the No6 jersey. Tohu Harris and Te Maire Martin would appear to be the two contenders, though Jordan Kahu could also fill the role.
"We are going to play around with a few combinations," said Kidwell. "That is what training is for. We have got a couple of options but we have to make the right option. Hindsight is a lovely thing but whoever we have in there we will have full confidence they can get the job done."
The Kiwis travelled down the M62 from Manchester to Liverpool today, where they will be based for the rest of the week. They have a promotional school visit tomorrow morning before an afternoon training session in Wigan.
