Gumleaf Grasshopper - nymph

A small nymph about 30 mm long so well camouflaged that it was hard to pick it out from the surrounding dead gum leaves. The whole body was a uniform grey-brown. A midline thoracic ridge made it look a little hunched. Antennae were short and the same colour as the body.
Spotted amongst gum leaf litter in a national park - Churchill Nat. Park.
