Australia fan Adrian Hobson watched the semifinal while at work at the Viaduct Sport Grill.
The duty manager, whose mother is Australian and father a Kiwi, expected his team to take out the tournament.
"I do think Australia is going to win. [David] Warner was a bit disappointing but that's Warner - sometimes he's in, sometimes he's not," Mr Hobson said of last night's match.
A New Zealand and Australia final would be great, he said.
"It's always going to be hard against New Zealand. They always lift the level, especially when they're playing Australia. I think it will be a hard ask at the MCG."
Thousands of fans who can't make it to Melbourne are expected to cheer among Fanzone crowds as New Zealand's cities gear up to support the Black Caps.
