Dendrocnide excelsa, also called Australian nettle tree, fibrewood, gimpi gimpi, giant stinging tree, gympie, is a rainforest tree of eastern Australia. It occurs from Tathra, New South Wales to Imbil in southeastern Queensland, and is very common at Dorrigo National Park and other rainforest walks in eastern Australia. The habitat of the giant stinging tree is subtropical, warm temperate or littoral rainforest, particularly in disturbed areas, previously flattened by storms or cyclones.
