It's Yowie

"The Yowie is a hominid cryptid in the same tradition of the North American Bigfoot and the Himalayan Yeti. The first known recorded account of the Yowie appears as early as 1876, but they have apparently been a part of Aboriginal folklore since a much earlier time. They can stand up to six or seven feet tall with bodies covered in black or brown fur. Although they are bipedal creatures, they have been reported as running on all fours. They are most commonly reported in New South Wales, the Gold Coast of Queensland, and in the bush country of the Moehau Range. There have even been reports of sightings in the North Auckland and West Coast areas of New Zealand. They have been sighted as recently as 1997 when a woman living in the Tanimi Desert was awoken at 3 a.m. by a seven foot tall creature covered in hair. The police discovered gigantic footprints and a shredded irrigation pipe on the scene. There are various theories concerning the truth about the Yowie. One of the most popular was put forward by self-proclaimed archeo-cryptozoologist Rex Gilroy. Gilroy argues that the yowie may be the remnants of an extinct ape species or even a less evolved version of homo sapiens.
