No music. No voices. Just the sound of a creek bed in outback Australia. In the Murchison district in Western Australia you're surrounded by low lying ranges where rocks have been found that are 4.4 billion years old — they're almost as ancient as the planet itself. Among the crests and dips of Wajarri country is a creek bed on Boolardy Station. Not flowing, but water is still there. And the places where there is water in this arid environment – well, it's a mecca for birdlife. Listen for: chiming wedgebills, lots of flies and other insects, rainbow bee-eaters, crested bellbirds, babblers and diamond doves among many many more.  Mix Engineer: Isabella Tropiano. This program is produced on the land of the Wathawurung people.
