New Zealand go unbeaten into the title clash in Melbourne on Sunday and even though the Brendon McCullum-led side has won all their eight matches on home shores, playing in Australia would certainly test their true mettle.
Crowe believes that Australia will certainly be a tough opposition to match.
"It's the unknown. Nobody played at MCG, probably only Daniel Vettori and Brendon McCullum, I am not sure. But they will have to dig in their reservoir of resources, their own own resilience and that's where they are playing their game from," Crowe told PTI in an exclusive interview ahead of the World Cup final.
The Kiwis have got the better of Australia in the league stages when they edged past the Kangaroos by 1 wicket in a low-scoring thriller at Eden Park, Auckland, but Crowe still feels that the Micheal Clarke-led side is a hard nut to crack.

"I mean Australia bring a very powerhouse kind of game. It's a lot of brawn and they are very bullish about it," said Crowe.
Crowe has a lot faith in the ability of Kiwi fast bowlers.
"New Zealand have got a lot more skill in the fast bowling department, with their fast swing," he said.
Despite the presence of spinners like Daniel Vettori and Glenn Maxwell in the respective sides, Crowe opines spin will not play much of a part at the MCG.
