Most of the population of around 1,800,000 live in the capital city Perth, approximately 1.3 million, most of the rest live close to the coast line. By comparison Frances population is 58 million and Texas has a population of 17.5 million. When travelling in W.A. there are a lot of wide open empty spaces, especially up north, I like to allow an hour per 100 kilometres as a guide to how far you can go. Try to stop frequently to give yourself a break. Try to resist the temptation to disappear down tracks unless you know where you are or if it is well used track.
People have been stranded out in remote place, some never make it back.
You are not going to see everything in a week, even a month is pushing it.
