No, there are no wild monkeys native to Australia. The only primates found in the country are species that have been introduced by humans.
Australia’s unique environment is home to a variety of native wildlife, but primates, including monkeys, are not part of its natural fauna. The continent’s isolation has led to the evolution of many unique species, but primates originated from different areas, primarily Africa and Asia, and have not naturally migrated to Australia.
Occasionally, you might find monkeys in Australian zoos or sanctuaries, and there are also some populations of monkeys in captivity as pets, but these are not wild monkeys. Therefore, if you’re traveling in Australia, you won’t stumble upon a troop of monkeys in the wild.
