Australia. It's a big place. With only a handful of heavily populated areas. And a whole lot of nothing in between.
No, really. Nothing.

Over the past century or so, much has been achieved in combating the famous Tyranny of Distance that naturally afflicts this land. High-quality road, rail, and air links now traverse the length and breadth of Oz, making journeys between most of her far-flung corners relatively easy.
Nevertheless, there remain a few key missing pieces, in the grand puzzle of a modern, well-connected Australian infrastructure system. This article presents five such missing pieces, that I personally would like to see built in my lifetime. Some of these are already in their early stages of development, while others are pure fantasies that may not even be possible with today's technology and engineering. All of them, however, would provide a new long-distance connection between regions of Australia, where there is presently only an inferior connection in place, or none at all.
