Boomerang - “A thrown tool, typically constructed with aerofoil sections and designed to spin about an axis perpendicular to the direction of its flight. A returning boomerang is designed to return to the thrower, while a non-returning boomerang is designed as a weapon to be thrown straight and is traditionally used by some Aboriginal Australians for hunting.” (Source)

Koalais - “An arboreal herbivorous marsupial native to Australia. They rely heavily on their sense of smell to make better food choices and detect other koalas’ scent markings on trees. Also, the koala may sleep or rest for up to 18-20 hours every day while being tucked into the fork of the tree. Because of its distinctive appearance, the koala is recognized worldwide as a symbol of Australia.” (Source)
