The Yowie — known variously as the Dulagarl, Jimbra, Yahoo, or Hairy Man — is an undescribed upright hominid reported for at least the last 150 years across Australia's eastern ranges from the Blue Mountains of New South Wales north through the Great Dividing Range into south-east Queensland. Aboriginal traditions long pre-dating European contact describe the creature in the Gundungurra, Gomilaroi, Yuin, Bundjalung, and dozens of other language groups. Early European settlers recorded encounters as early as the 1830s: surveyor Charles Reynolds published an account of a 'wild man' near the Hawkesbury River in 1835, and a letter published in the Sydney Evening News on December 7, 1882 described a seven-foot creature with 'long hair and red eyes' observed above the town of Grafton.
The modern Yowie corpus contains more than 4,000 sighting reports catalogued by researchers Dean Harrison (Australian Yowie Research) and the late Rex Gilroy. Concentrated sighting zones include the Blue Mountains around Katoomba, the Bunya Mountains of Queensland, the Barrington Tops and Watagan ranges, and the wet-sclerophyll forests of the Springbrook Plateau. In February 1978, a motorist on the Monaro Highway near Cooma described a six-foot-tall creature crossing the road in front of his car; the animal left clear tracks in the dirt shoulder that were photographed and measured at 42 centimetres long. In October 2002, brush-cutters working near Mount Glorious, Queensland encountered a 'huge hairy man' which growled and threw rocks at them.
Skeptics propose that Yowie reports conflate the eastern grey kangaroo rearing upright, escaped domestic cattle, or the occasional orang-utan fugitive from a private menagerie; none of these explanations accounts for the Aboriginal antiquity of the tradition. Some cryptozoologists argue the Yowie may represent a surviving population of Homo erectus or Gigantopithecus, noting that the Australian continent's biogeographic isolation has preserved other megafaunal relicts far longer than on connected landmasses. Whatever the underlying reality, the Yowie is one of the world's most thoroughly-documented cryptid traditions.
