Zillie Falls is a waterfall located on Theresa Creek in the Atherton Tablelands of Queensland, roughly 106 km southwest of Cairns and about 7. 5 km from Millaa Millaa Falls.

It sits on the outskirts of Wooroonooran National Park and is the middle waterfall of the famous 17-kilometre Waterfall Circuit, which also takes in Millaa Millaa Falls and Ellinjaa Falls.

The entire circuit follows sealed Theresa Creek Road and is accessible to all vehicle types.

A short, flat walk from the car park leads to a viewing platform that offers a direct outlook over the falls, making it one of the more accessible stops on the circuit.

Together with its two companion falls, Zillie Falls is considered among the most photographed waterfalls in Australia.
