The Centralian Tree Frog (Ranoidea gilleni, formerly Litoria gilleni), is found in a small region of Central Australia. It has a dark olive to bright lime green dorsal, with small cream to white spots and blotches. The spots distinguish the Centralian Tree Frog from the Australian Green Tree Frog.
The frog can appear a bright green in water, then on leaving the water, it can darken to a dark olive green (see images). The under belly of the frog is cream to white.
