Australia

Australia, officially known as the Commonwealth of Australia, was the largest country in Oceania before the Great War.

Background
Skeletons of horned kangaroos, mutated creatures native to Australia, can be found in Fallout and Fallout 2.

The entomologist and mammologist exams at the Pioneer Scout camp have questions that also reference the country. A question in the entomologist exam asks, "Caterpillars go through some changes in their life as they grow older. Sound familiar, kids? But in the end they turn into a beautiful new creature! What creature?" The four-legged Australian termite beetle is provided as an incorrect answer to the question. Additionally, two questions in the mammologist exam reference the Australian continent. The first is "You're hiking in the woods near your house and spot a red fox. Red foxes are native to North America. Which of these continents are they not native to?", where Australia is provided as the correct answer to the question. The second is "Australia is home to a class of mammals called marsupials. What's special about most marsupials that's different from other mammals?"

The dog breed Australian Shepard is available as a pet in Fallout Shelter.

Appearances
Australia is mentioned in Fallout, Fallout 2, the Fallout 76 update Wild Appalachia, and Fallout Shelter.
