Capital of the Northern Territory (NT), with an estimated population of 150,000, Darwin is home to most of the Northern Territory population. The Darwin region, like much of the Top End, experiences a tropical climate with a wet and dry season and boasts a vibrant multicultural community, where Indigenous heritage blends seamlessly with the influence of diverse international populations. Darwin's rich history provides an incredible background for the diverse cultural and historical activities. On the 9th September 1839, HMS Beagle sailed into Darwin harbor during its survey of the area. John Clements Wickham named the region “Port Darwin” in honor of their former shipmate Charles Darwin. The city has been rebuilt almost entirely four times, following cyclones and Japanese air raids in World War II.
