On first glance, the tiny outback town of Kununurra, population 5000, is the last place you'd expect to rub shoulders with some of Australia's hottest movie stars. It's as close to the middle of nowhere as you can get, (3247km north of Perth, 512km west of Katherine, 1518km north-west of Alice Springs), but for a few months last year, during filming of Baz Luhrmann's Australia, that's exactly what happened.
