The gallery forest along the creek contains as dominant species Melaleuca viminalis, Callitris intratropica, Melaleuca leucadendra, Tristaniopsis exiliiflora, Banksia aquilona and Bursaria tenuifolia with the open forest adjacent to the track to the falls mainly dominated by Eucalyptus leptophleba and Eucalyptus granitica. Two plant families in particular have been overlooked namely the Fabaceae and the Poaceae. Further visits and collection of specimens for identification would be necessary for these difficult to identify in the field families.

Jago) The substrate and outcrops adjacent to the falls are composed of Tinaroo Granite (280-270 million years of age) with the face of the falls composed of a fine grained aplite dyke, which was probably injected around the later stages of the solidification of the Tinaroo Granite.
