A group of friends on a trip into the Australian outback (Hallet Cove) claimed they saw a strange alien/humanoid creature lurking around the cliffs. Of course, nobody believed them. The next time they went out to the same place, they brought a camera along in hopes of seeing the alien again. This is their footage.
While not the same group of friends, and definitely not in Australia – here is another quick clip I found of an alleged alien lurking in some bushes. Not much is known about the origins of this video. I guess those aliens just love lurking in bushes?
