it's not a tessellated, it's a Juvenile Titan Stick Insect, Acrophylla titan, you can tell this by the shape of the cerci, in Anchiale the cerci are flat and rounded at the end, whereas in a Titan they are wavy. See this link with a photo of an Anchiale and info in the post from expert Matthew Connors. http://www.bowerbird.org.au/observations/61380
