New Zealand.

The term references the similarities between the Australia-New Zealand and United States-Canada relationships. Each pair maintains strong ties, though also trades (usually) good-natured jests and barbs.

Both Canada and New Zealand have smaller populations and can be said to "live in the shadow" of their more well-known neighbor. Each is also known for outstanding natural beauty and friendly people.
Person 1: "Geez. Those Aussies and Kiwis are really going at it over there. They really must hate each other."

Person 2: "Nah, they're just drunk and being dumb. New Zealand is Australia's Canada. They'll be friends again in the morning."
