Side by side

Population density

New Zealand is 5.6 times more densely populated than Australia — 20 against 4 people per km². Density is where area and population interact, and it often reverses the impression the headline figures give — a large country with a small population can feel emptier than a small crowded one by an enormous margin.

Practical differences

• Different currencies: the Australian dollar and the New Zealand dollar.
• Australia spans 5 time zones, so "local time" there is not a single answer.

Australia

The sixth-largest country in the world and the only one that covers an entire continent. The Great Barrier Reef runs about 2,300 km and is the largest structure made by living organisms on Earth, visible from orbit. Around eighty percent of its mammals, reptiles and flowering plants exist nowhere else. Melbourne and Sydney are within roughly a hundred thousand people of each other, and which counts as the largest city depends on where the boundary is drawn.

New Zealand

Two main islands and around 600 smaller ones, roughly 1,600 km long. New Zealand broke away from Gondwana about 80 million years ago and had no land mammals except bats until people arrived, which is why so many of its birds are flightless. The Southern Alps run most of the South Island and reach 3,724 m at Aoraki / Mount Cook.

Neutral facts only. Nothing here addresses politics, government, economics or which country is preferable in any respect — population is the one figure that dates, and it carries its year.
