Triplet Falls, Waterfall in Great Otway National Park, Australia.

Triplet Falls comprises three separate cascades that flow through ancient forests filled with tall mountain ash and myrtle beech trees. The falls sit deep in a dense wooded area in southeastern Victoria and are reached by following a walking trail.

The falls lie in the Great Otway National Park of Victoria, about 200 km from Melbourne via Colac and Gellibrand and 70 km from Apollo Bay. They are fed by Young Creek, whose three streams cascade over rainforest into the valley floor. The surrounding stands of mountain ash and myrtle beech are among the area's old forests.

The name comes from the three streams of Young Creek that cascade over the valley floor, though only one or two may run when upstream rain is scarce. The surrounding mountain ash and myrtle beech forest is part of the Great Otway National Park, reached via a walking trail from the car park.

The round-trip walk is about one hour and covers two kilometers through the forest. An elevated viewing platform at the falls gives good views of all three cascades and keeps feet safely away from wet, slippery rocks.

Water flow varies greatly depending on rainfall, so in dry periods only one or two of the three cascades may be running. This means each visit can look quite different based on how much water is moving down the falls.
