Hi @PeterMiller4722 The species is correct Osphranter robustus. The sub-species erebescens refers to the widespread form with reddish grey fur. Along the Great Dividing Range (including here in the ACT) is the sub-species originally named. There are sometimes tiny flecks of reddish fur in a few of our our local males when you have them in the hand but mainly they are the dark grey shown in your images. The local females are a very pale and lovely light grey, paler and greyer than Eastern Grey Kangaroos. Erebescens females are the same as erebescens males.
