The term 'Australian Bigfoot' refers to the YOWIE, a cryptid believed to inhabit the Australian Outback. The YOWIE is a large, ape-like creature that is said to be similar to the North American Bigfoot. It is believed to be a remnant of an ancient species of hominid that has survived in the Australian bush. Reports of sightings of the YOWIE date back to the early 19th century, and it continues to be a source of fascination for cryptozoologists.
