Winpa is a jila (living waterhole) in the Great Sandy Desert on the edge of the Percival Lakes. It is an important rain making place that was created by the last ancestor to change into the landscape.

Winpa had travelled to the south and seen all his countrymen changing into sacred snakes inhabiting important waterholes. He was the last one to lay down and was a very powerful law man and rainmaker. He rested near his five sons. He is still active today.
