funnitly enough, i have driven the Sturt 2 times, the nullabor 2 times, and almost the entire state of NSW and QLD, and have only ever hit 2 kangaroos that have done some serious damage, 1 on the Heathcoat road on the way to YSBK from Cronulla, and the other on the F6 to wollongong... though i almost collected an Emu crossing the road on the way to white Cliffs.
