Were you asking about the Nullarbor as well? Vehicle suicide at night, countless small kangaroos, if you get caught short of your stop you will be down to 70-80km/h there are so many of them. I havent honestly had as much trouble on Stuart highway but you get cattle standing motionless all along the thing and in the dark you see those red ones (droughtmasters?) way too late. I agree with previous post, very boring, try and do it in 2 days (from Adelaide)
