Staghorns and orchids cling to trees and rocky ledges. Soft tree ferns, bracken fern and vines also add to the rainforest's luxuriant appearance. Open eucalypt forest grows over most of the park. Canopy trees include brush box, forest red gums and stringybarks with small trees of forest sheoaks, kurrajongs and wattles. In drier areas of the park the open forest has a shrubby undergrowth and grassy forest floor.
Spring Creek provides a home to animals such as the platypus and a red spiny crayfish.
The brush-tailed rock wallaby is one of the rarer animals in the park. Sleeping through the day, this wallaby is not easily seen by visitors. These rock wallabies move gracefully through the rocky gorge and are able to negotiate almost vertical rock faces. They graze and browse on a wide variety of plants n open grassy areas of the park. About 100 bird species have been found in the park, including the shy Albert's lyrebird.
