Set in the far northwest, the Kimberley is one of the most rugged and remote regions of Australia. Closer to Jakarta than to Sydney, its 135,600 square miles are home to just 35,000 people. Cattle stations take up some of that space, but for the most part, the landscape comprises craggy sienna-hued ranges, emerald forests and wetlands, and forbidding cliffs that plunge into the ocean.
