The Eungella tinkerfrog is considered near threatened in Queensland. It occurs between 180 and 1250m elevation, but is sparsely distributed and rarely seen. Potential threats to this species include forest grazing, trampling by livestock, introduced species such as the cane toad ("Rhinella marina") and the chytrid fungus. The northern gastric brooding frog ("Rheobatrachus vitellinus") was discovered in January 1984, but has not been seen since March 1985 and is believed to be extinct. It is one of only two species in the world known to brood its young in its stomach, with the mother swallowing fertilised eggs or early larval stages, before ‘giving birth’ through the mouth. Its distribution was exclusively undisturbed rainforest within Eungella National Park at altitudes of 400-1000m, before it underwent a sudden range contraction and disappeared.  28 species of mammals have been recorded in the park. This includes several bat species including the little bent-wing bat ("Miniopterus australis"), eastern horseshoe bat ("Rhinolophus megaphyllus"), common blossom bat ("Syconycteris australis"), eastern forest bat ("Vespadelus pumilus"), eastern long-eared bat ("Nyctophilus bifax") and grey-headed flying-fox ("Pteropus poliocephalus"). Platypus ("Ornithorhynchus anatinus") are often seen at the viewing platform at Broken River which is the most visited location in the park. They have an unusual foraging behaviour and are the only mammal known to use electrolocation for detecting prey. Platypus are generally found in slow-moving rivers and small pools and are highly adapted to a semi-aquatic life. They have extremely dense fur, large webs on their feet extending well beyond the toenails, a broad, flat tail and excellent swimming ability, paddling with their forelegs in alternating strokes, with their hindlegs and tail trailing behind. When foraging, captured prey is stored in two cheek pouches and later masticated and swallowed when the platypus surfaces. An apparent feeding association has been noted between the azure kingfisher ("Ceyx azureus") and the platypus at Eungella National Park, where the birds have been observed watching for fish disturbed by the platypus, before diving into the water in search of prey.  20 species of reptiles occur in the park.
