What does nomad mean in Australia? Other than a tourist? Or a traveller?

The word nomad conjures up: flat deserts and sand, springs of water and a sense of desolation. This gives us a feel of the country, the flatness of Australia, the strangeness of the names attached to the pools and waterholes, the Australianness of Australia or at least that part around Broome, anglicised for us tourists as Roebuck Plains: which lets us know, that reassures us, as do the illustrations, that European man has trodden this land, has marked this land, has rendered it into the pastel shades of civilisation of the European variety.
