Northern Territory House Suburbs

Overview

The Northern Territory is home to about 260,400 people (March 2025), with roughly half residing in the capital Darwin and the remainder spread across Palmerston, Alice Springs, Katherine and other coastal centres along the Stuart Highway. The population is the youngest in Australia, with a median age of 31 years and Indigenous Australians accounting for around 30 percent of residents.

Economic activity is anchored by mining and petroleum, which together contributed $5.68 billion to gross state product in 2018‑2019 and supplied over 90 percent of the territory’s exports, while recent infrastructure projects have moved construction into the position of largest single industry. The territory’s gross state product per‑capita exceeds $70 000, reflecting growth rates that outpace the national average.
