On a path, a dragon lizard basks. I think this is a Tympanocryptis diemensis, commonly called a mountain dragon.
and closer:Here's a picture taken of another lizard, trustworthily labelled T. diemensis by a more herpetologically aware photographer, so you can compare the two as well.
As to whether dragon #2 is also a T. diemensis, I don't know, and am not going to assume. And does it matter, really, if I cannot tell you anything else about them? I came upon a female dragon once. She looked much like these—not basking, but laying eggs in a hole in the middle of the sunwarmed path. She was a type of dragon lizard, but Australia sports dragons in 60 flavours, not to mention an unparalleled variety of other lizards, many of whom have names longer than what's known about their lives.
