I'd not only like to see Uluru, but I'd also love to visit other parts of the Australian desert. My uncle and his family lived in a remote Indigenous community for a number of years, and the way he speaks (and writes poetry) about the desert... well, one day I'm going to have to go and see it for myself.
Do you mind if I ask what your brother was working at in WA? The first thing that sprang to my mind was "mining", but I am probably way off the mark.
Not too far off. He works in the oil industry, travelling to exotic locations all over the world. He was offered a long-term job in WA, but his wife didn't want to live there (she felt more comfortable in Scotland).
