Rare fauna inhabiting Mount Banda Banda include the Hastings River mouse, Parma wallaby, sphagnum frog, Booroolong frog, giant barred frog, stuttering barred frog, the tree dwelling snail, the olive whistler, and the rufous scrub-bird, which was described by the International Union for Conservation of Nature as being of universally outstanding significance to science and conservation. The reptile and invertebrate fauna of the mountain are not yet comprehensively understood. However, as this Gondwana rainforest is in good condition, future surveys should provide a valuable picture of the local ecology.
