Billy Falls is an unofficially named waterfall on Billy Creek in Tasmania, located a short distance from Southwood Road. The falls drop approximately 10 metres over a rippling, textured cliff face, fanning out into a large pool below.

The water carries a notably brown discolouration, likely influenced by the surrounding forest, which was heavily burnt in the 2019 bushfires. Reaching the falls requires a short but steep off-track hike through the fire-affected bush.

Access begins from a large pullout on Southwood Road, roughly 5 kilometres from its intersection with Arve Road near Geeveston, just before the road crosses a culvert over Lidgerwood Creek.

From there, visitors walk a couple of hundred metres up the road before heading into the bush toward the waterfall, arriving at views from atop the creek's drainage within about 200 metres.
