A vast and diffusely populated country, Australia has corners that many tourists will never see. One of those places is Cook, a ghost town in South Australia, which was built when the Trans-Australian Railway was created back in 1917. It's nestled in the middle of nowhere, somewhere along the longest straight railway track in the world. In fact, it's around 513 miles (826km) away from Port Augusta by train and 62 miles (100km) north of the Eyre Highway.
