Wallaman Falls is Australia's tallest single-drop waterfall, plunging 268 metres (879 ft) down Stony Creek in a cascade and horsetail formation.

It sits within Girringun National Park, part of the UNESCO World Heritage-listed Wet Tropics in the Shire of Hinchinbrook, northern Queensland. The pool at the base reaches 20 metres deep, and the falls are permanent — flowing year-round regardless of season.

Surrounded by dense tropical rainforest, the drop is often framed by a cloud of rainbow-tinged mist. The site draws an estimated 100,000 visitors annually, drawn by both the spectacle of the falls and the broader World Heritage landscape that encloses them.
