According to a legend told by the Wurundjeri people of the Kulin nation, in the Dreamtime the Karatgurk alone possessed the secret of fire.
Each one carried a live coal on the end of her digging stick, allowing them to cook the yams (murnong) which they dug out of the ground.
The sisters refused to share their coals with anybody, however they were ultimately tricked into giving up their secret by Crow.
Shrieking, the sisters struck the snakes with their digging sticks, hitting them with such force that the live coals flew off.
The women soon discovered the theft and chased him, but the bird simply flew out of their reach, and thus fire was brought to mankind.
