What is "wati-kutjara"

In Australian Aboriginal mythology, the Wati kutjara (also Wati kutjarra or Wadi Gudjara) are two young lizard-men ( totem: goanna) who, in the Dreaming, travelled all over the Western Desert. In English, their songline is often called the Two Men Dreaming. The Wati kutjara are ubiquitous in the mythology of the Western Desert; indeed, their journey extends for thousands of kilometres, stretching from the Kimberley to South Australia.
