Animal Facts About Australia

An underground fire in Australia has been burning for approximately 6,000 years, making it the world's oldest known coal fire.

Koalas are the only non-primates with fingerprints, and their prints are so remarkably similar to human fingerprints that even careful analysis under a microscope cannot distinguish between them.

Australia's Great Barrier Reef stretches over 1,400 miles, making it the largest living structure on Earth visible from space.

Koalas are not bears—they're marsupials more closely related to wombats and kangaroos.

According to news reports, a feral pig in Australia drank 18 cans of beer, brawled with a cow, and then passed out under a tree.

A kangaroo cannot jump if its tail is off the ground.

Male kangaroos flex their biceps to impress females.

Emus and kangaroos cannot walk backwards.

A koala sleeps up to 22 hours of every day.

Large kangaroos can cover more than 30 feet with each jump!

In Australia, there are spiders big enough to eat snakes.

A species of earthworm in Australia grows up to 10 feet in length.

Valerie, a miniature dachshund, escaped her owners on Kangaroo Island, Australia and survived alone for 529 days among kangaroos, snakes, and heat waves. After 1,000+ hours of searching, she was finally caught using strips of her owner's worn shirt as bait. She came back 4 lbs heavier.

Quokkas are known as the world's happiest animal because they always look like they're smiling. But when a predator shows up, mothers eject their baby from the pouch and let it flop around on the ground as a distraction while they run away.

Researcher Dominique Potvin spent years designing GPS harnesses for Australian magpies - magnetic releases so only she could remove them. Within 10 minutes of fitting the fifth bird, an untracked female magpie freed a younger bird's harness. By day three, all five trackers were gone. It was the first documented case of birds helping each other remove tracking devices.

The wombat is the only animal on Earth that poops in cubes - 80 to 100 neat, flat-sided blocks every night. For years nobody knew how; everyone assumed a square exit. There isn't one. Engineer Patricia Yang mapped a wombat's intestines and found two stretchy groove regions where the gut wall flexes unevenly, moulding the waste into cubes. The wombat then stacks them to mark territory - and cubes don't roll away.

Bear was an Australian koolie nobody wanted. His family gave him up - he ate through the walls of their apartment. Researchers saw his obsession as a skill. They trained him to sniff out koalas in burned forests, up to 20 times faster than any human search team. During Australia's 2019-20 fires, he found over 100 koalas. He retired in 2026 after ten years of service. The drive that no family could live with saved hundreds of koalas.

Old Tom was a wild orca in Eden, Australia. He led a pod that helped whalers hunt whales for 70 years. He slapped his tail at the river mouth to signal a whale had arrived. Sometimes he signaled after dark too. In return, they left the tongue and lips for the orcas. His skeleton still hangs in a museum today, teeth worn into half-circles from towing ropes.
