Injuries and unavailability have hit the Kiwis hard and five players will make their test debuts when they face the Kangaroos in Sunday's one-off international in Newcastle.
Up to 12 players are unavailable for the Kiwis' Four Nations campaign including Manu Vatuvei, Steve Matai, Shaun Johnson and Sam Rapira but the debutants bring growing NRL experience and four of the five have been called up to the Kiwis before without playing.
Kevin Locke and Russell Packer were part of the 2009 Four Nations squad and Gerard Beale and Alex Glenn have previously been involved in Anzac test campaigns as 18th man. North Queensland's Kalifa Faifai Loa, who will debut on the wing, is the fifth newcomer and all five played in the NRL finals.
Glenn has got the closest to playing test football before after being involved in the Anzac test campaigns of 2009 and 2010. Last year he played for the Cook Islands and he was also in the Junior Kiwis side that beat the Junior Kangaroos in 2007.
"I never gave up hoping and just kept working," Glenn said. "It was great being around the Kiwis in 2009 and 2010 but I always dreamed of going that one step further and pulling on the jersey to play for my country. To be making my debut against the Aussies this weekend is unbelievable. I can't wait to get into it."
