Trans-Tasman rivalry is set to reach new levels on Sunday morning when the Wallabies and All Blacks square off in the Rugby World Cup final at Twickenham.
Not surprisingly, New Zealand fans can't see their team losing.
Staunch Aussie supporters are also confident their boys can get the job done.
We've asked one passionate supporter from either side of the ditch to come up with five reasons why their team will become the first to lift the William Webb Ellis trophy for the third time.
1: Captain/coach combination. Michael Cheika is one of the best coaches in international rugby, and in Stephen Moore he has one of the most respected captains in the game. Together they have created a formidable team - think Bob Dwyer and Nick Farr-Jones in '91 and Rod Macqueen and John Eales in '99.
2: Form. The Wallabies are battle-hardened after having overcome Fiji, England and Wales in the "Pool of Death", and Scotland and Argentina in the finals. The All Blacks, on the other hand, have had a picnic.
3: Defence. It wins matches, especially the big, tough, tight contests. If the Wallabies can hold out Wales with 13 men, they can withstand anything.
4: Justice. It was a Kiwi, Robbie Deans, who, as Wallabies coach, unceremoniously dumped Matt Giteau into the wilderness of French provincial rugby. Matt is back and his experience, composure, defence and booming left boot will prove crucial.
5: The underdog bites back. The Aussies have lost rugby league world dominance to the Kiwis. Enough is enough. The 2015 Wallabies are a special team and will turn the tables on their more fancied rivals.

1: Composure. This All Black team has a phenomenal record of winning in tight situations. It has lost just three times since winning the tournament four years ago. They've launched many incredible come-from-behind wins. They don't get rattled.
2: Game smarts. You won't see the naivety the Argentines displayed. They'll play in the right parts of the field, and ball runners won't get isolated. Yes, Pocock and Hooper are playing well. But you don't play to the opposition's strengths.
3: Kicking. The Iceman? Please. Bernard Foley wobbled against Wales and even last week wasn't faultless. Dan Carter's the man under pressure - you can put your house on it.
4: SBW. He can't make the starting XV, but when Sonny Bill Williams comes off the bench, sparks will fly. There is not a better game-changer in team sport.
5: History. The Blacks will be more desperate. Richie McCaw, Dan Carter, Ma'a Nonu and Conrad Smith are on their way out and want to be the first to win back-to-back World Cups. And will the Kiwis let the world's greatest player, McCaw, leave with anything but a win?
