Canberra Raiders Joel Monaghan and Bronson Harrison will face off for World Cup glory at Suncorp Stadium on Saturday night after retaining starting positions for their respective countries.

New Zealand coach Stephen Kearney yesterday named Harrison in the back-row for the match against Australia, rewarding the 23-year-old for an excellent semi-final performance against England last week.

Monaghan retained his spot on the wing for the Kangaroos, meaning he will have played in all four of Australia's World Cup games after debuting against England.The final will be the culmination of a whirlwind month for

Harrison, who was only called in to New Zealand's World Cup squad because of an injury to fellow back-rower Iosia Soliola.

The Raiders recruit was a surprise starter in last weekend's semi-final against England, but he proved Kiwi coach Stephen Kearney's judgement was spot on by scoring a superb try after steaming onto a pass at an angle that made him unstoppable.

''He's a young guy who's really grabbed his opportunity,'' Kearney said.

''He wants to learn. He's worked very hard on the training paddock and in the gym. When you have a kid so determined to do well, half your job is done.''

Kearney and Stuart named unchanged lineups for the final, but Australia's Brent Tate (hip flexor strain) and Paul Gallen (corked thigh) remain under an injury cloud.

Kearney said his five-eighth Benji Marshall held the key to his team's chances of upsetting the highly-fancied Kangaroos, but was hesitant about heaping too much pressure on the Wests Tigers star.

''He's shown glimpses [of his best],'' Kearney said.

''What we'd like from Benji is for him to string that kind of form together for 80 minutes.

''I'm relying on the 16 other players. The forwards know if they can build a platform for the likes of Benji and Nathan [Fien] to work off the back of, we give ourselves a good chance.

''I hope for Benji's sake he does. He's the sort of player who can do something special.

''We're well aware of that and I'm sure so are Australia.''In good news for the Raiders, five-eighth Terry Campese has recovered from an eye injury and resumed light training with the Kangaroos.

Campese suffered a blood clot and bruised retina in his right eye during Australia's win over Papua New Guinea a fortnight ago and he was confined to his hotel room for a week.
