TREE SKINK Egernia striolata (Peters, 1870)
This 25 cm lizard is in many respects similar to the Black Rock Skink, from which it may be differentiated by its' usually lighter and more well defined colouration. The Tree Skink is found throughout inland eastern Australia and the coast of Queensland.
Usually found in trees, under bark, particularly around river flats, this species is sometimes found in large numbers around rock outcrops, particularly in arid areas.
Around rock outcrops this lizard lives in crevices. The diet is of this lizard is mixed, and it produces 2-3 live young, measuring 6 cm.

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.
