In 2010 a mystery animal researcher ventured into a bush location in the Blue Mountains, west of Sydney. For several minutes he recorded the sound of something walking nearby and throwing what were possibly rocks towards him.
Another researcher, 'Bluegem', who has a background in sound engineering, managed to dampen the man's voice and footsteps so that the other sounds could be more clearly heard.
Thank you to both gentlemen for sharing this audio with us. What do you think, readers?
