An officer with the Department of Parks and Wildlife in Western Australia captured an incredible photo near the town of Walpole and posted it on Facebook with the caption: "Dinner time!"

The department explained: "This highly venomous tiger snake didn't stand a chance when a hungry southern heath monitor came looking for something to munch on.

"Captured by our Frankland district flora officer Janine Liddelow, this shot was taken on a forest track. The southern heath monitor can be found north and south of the Swan River and in the state's far south-west."

They can grow up to 1.5m in length and have a diet of birds, reptiles, small mammals, eggs and carrion.
