The red kangaroo (Macropus rufus) is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial. It is found across mainland Australia, avoiding only the more fertile areas in the south, the east coast, and the northern rainforests.

The platypus or duck-billed platypus (Ornithorhynchus anatinus) is a semiaquatic egg-laying mammal endemic to eastern Australia, including Tasmania. It is one of the extant species of monotremes, the only mammals that lay eggs instead of giving birth.
