Australia

In 1932, Australia waged war on emus — and lost. To stop ~20,000 emus wrecking crops, soldiers brought two machine guns and 10,000 rounds, but the birds split into small groups and outran the fire; one gun jammed. After two months, under 1,000 were killed — the war birds won.

New Zealand's Māori did not come from Australia but descend from people who left Taiwan. By canoe through the Philippines and Papua, they reached New Zealand around 1200–1300 CE. Before their arrival, the islands had no humans—and no mammals at all.

The distance between Australia and New Zealand exceeds 2,200 km—farther than Seoul to Ulaanbaatar, Mongolia. The sea between the two countries is roughly large enough to fit India entirely.

In 1859, a British settler in Australia released 24 rabbits into the wild. With no predators and mild winters, they multiplied into billions. Australia tried continent-spanning fences, foxes, poison, disease, and the military—all failed. The rabbit war continues to this day.

In 1927, Australian physicist Thomas Parnell began an experiment: letting pitch (tar)—solid-looking, shattering when struck—drip from a funnel to prove it is liquid. The first drop took 8 years. Drops fall every 8–13 years, but no one has ever witnessed one fall.

In 1980s Australia, male beetles were found mating with beer bottles. The brown color, size, and bumps on the bottles mimicked female beetles, acting as a "supernormal stimulus." When this threatened the species, Australian breweries redesigned their bottles, removing the bumps.
