Final answer:
Neanderthals never migrated to Australia; instead, Homo sapiens arrived there at least 40,000 years ago.
Step-by-step explanation:
Neanderthals did not migrate to Australia. Instead, Neanderthals were a species of ancient humans that lived in Europe and parts of western Asia between approximately 400,000 and 40,000 years ago. There is no evidence to suggest that Neanderthals ever reached Australia. Anatomically modern humans, or Homo sapiens, are the ones who migrated out of Africa and into various parts of the world including Australia, where archaeological evidence suggests they arrived at least 40,000 years ago.
