Pretty much what MSR said. On the way home from Perth got to cocklebiddy on the first day and drove straight through to adelaide second, so it's not a long trip. However when I was going across to Perth they had problems with the Ultimate pump at Cocklebiddy and I had to use regular. Other than that it's a great trip! Make sure to stop at the Bight. I've been to some interesting places, but that is amazing.
