Yellow footed rock wallaby
Spotted this gorgeous fella in the Flinders Ranges , he was some distance away but he stopped for a second, then high tailed off. ( shot on a 600 mm lens)
Nikon D750 on a 600 mm Tamron lens , iso 4000 1/3 sec shutter , that can change with light pollution around you and sometimes different shutter speeds can make the object lighter or darker , and most of all use a tripod.
