Darwin is the territorial capital and most populous city of Australia's Northern Territory. Located on Australia's far northern coastline. It has the largest proportional population of Indigenous Australians of any Australian capital city, and a significant percentage of its residents are recent immigrants from South East Asia. As such, Darwin is often called the "multicultural capital of Australia" due to its additional mix of racial and cultural groups, including Timorese, Vietnamese, Filipinos, Papuans, Greeks and Italians. Darwin is an important port, particularly for the live export of cattle, minerals and gas. It is also the site of a large Australian Army base and a naval facility supporting patrol boat activity off Australia's northern coastline.
