You may have heard of Uluru, ‘the heart of Australia’. It is a cultural rock for the Indigenous people of Australia and attracts many tourists. The nearby airport would be a fantastic addition since it is the only one out of two airports in the middle of Australia (Alice Springs Airport is the other), which would make a fantastic refuelling stop on long distance flights or to operate domestic routes. Currently Qantas, Virgin Australia, Jetstar and other scenic helicopter tour operators have flights to and from here.
It would make a fantastic site seeing destination in global flight being in the middle of a desert with challenging conditions and with a picturesque landscape nearby Uluru (as you may already know, to the other side of the airport there are a few great hotels and resorts to stay, but nothing like a city)
