Bila (also occasionally rendered Belah^[1][2]) is the personification of the Sun among the Adnyamathanha people. She is a solar goddess, as befitting the general trends among Australian aboriginal peoples, which largely perceive the Sun as female.^[3]

Bila is said to be a cannibal, roasting her victims over a fire, the origin of sunlight. To do this, she sent black and red dogs to drag her victims, resulting even in an entire village being slaughtered.^[4] In a myth, the Lizard Men Kudnu ("Goanna")^[5] and Muda ("gecko")^[6] were appalled by these acts and attacked, prompting her to flee and cast the world in darkness. He then used a boomerang, catching her and making her move in a slow arc across the sky as it returned, it illuminated the world. For this act of heroism, lizards like goannas and geckos are respected by the Adnyamathanha.^[7][8]

A similar, albeit likely unrelated myth, occurs in Woodlark Island.^[9]
