Tin Mine Falls, Cascade waterfall in Kosciuszko National Park, Snowy Mountains, Australia.

Tin Mine Falls is a multi-tiered waterfall in the Snowy Mountains that cascades over bedrock with several smaller drops before plunging into a final pool through a punchbowl formation. The water flows across different levels, creating distinct steps along its descent.

Tin Mine Falls lies in the Pilot Wilderness Area of Kosciuszko National Park, reached by the Cascade Fire Trail running south from the Alpine Way west of Thredbo Village. Its name recalls tin mining, but the sources record no mining history at the falls. Height estimates range from 160–180 m, consistent with topography, to 360–459 m; the World Waterfall Database lists 213 m.

The name Tin Mine Falls does not refer to a mine: no tin was ever extracted here, and the falls lie in the Pilot Wilderness Area of Kosciuszko National Park. The nearest approach is the Cascade Fire Trail, running south from the Alpine Way west of Thredbo Village.

Access is via the Cascade Fire Trail starting south of Alpine Way west of Thredbo Village through demanding terrain. Wear sturdy footwear and bring plenty of water, as the path is tiring and can be exposed in places.

A 1990 measurement by Dr. John Pease reportedly used a plumb line to give heights of 360 or 459 metres, but the World Waterfall Database lists 213 metres and analysis of the topography suggests 160–180 metres. The falls sit in a punchbowl recess, so no single ground position shows the whole drop.
