TRYON'S GECKO Oedura tryoni De Vis, 1884
Common in ranges of north east NSW, and South Eastern Queensland, the Tryon's Gecko attains 17 cm. A rock dwelling species, most specimens are found sheltering under rock exfoiliations during the day, often in small groups of up to six individuals. At night specimens are found foraging on open rock faces in search of their insect diet.
Juveniles are more dull in colour than adults.

The above was from the book Australian Reptiles and Frogs by Raymond Hoser and now available on a fantastic CD-Rom along with a vast amount of other information, papers and the like on reptiles, frogs and other wildlife.
