Two interesting signs, showing that yes, you are in Western Australia.
The first $22 per hour for cleaners. Despite these rates (similar for waiting tables) travellers tend to stay only a few weeks and then move on. Indeed folk arriving in, say, Broome can pick up a decent paying job within a day.
The second speaks to the kind of people around. It seems the camel hire business is a lot tougher than it would otherwise seem.
