The NT is a strategic location for defence in an important part the Indo-Pacific region from an economic and regional stability standpoint. With a significant army, navy and air force presence in the NT, defence continues to be a consistent contributor to economic activity, providing stimulus to local businesses and supporting regional employment.
The 2020 Defence strategic update and the 2020 Force structure plan reinforces the importance of the Territory to Australia’s national security, with over $8 billion in infrastructure to be invested in the Territory over the next decade.
The local Defence population (including personnel and their families) is estimated at about 12,000 people. Defence personnel generally move to the NT on a two to three year posting, many with their partners and children, thus contributing to regular population turnover in the NT.
- Defence expenditure in the NT reached $2.2 billion in 2019-20, or 8.8% of the NT’s gross state product (Chart 1)
- This represents a 7.0% increase compared to the previous year, mainly reflecting a rise in operational expenses, partly offset by a decline in investment spending
- Defence expenditure in the NT as a proportion of total national defence expenditure represented 4.8% in 2019-20
- National defence expenditure accounted for 2.4% of Australia’s gross domestic product
- The number of defence personnel located in the NT increased by 0.9% to 5,433 persons in 2019-20 (including permanent personnel and reservists)
- This reflects the second consecutive annual increase, following seven consecutive years of decline since a peak of 7,234 people in 2009‑10
- Of the 5433 defence personnel, 3460 are in the army, 1033 are in the air force, 736 are in the navy, and 204 are Department of Defence civilians (Chart 3)
- About 81% of defence personnel in the NT are permanent forces
- Despite an increase in NT defence personnel in 2019-20, the NT’s share of Australia’s defence personnel decreased 0.1 percentage points to 5.2% from 2018-19
- Defence Housing Australia (DHA) managed about 1,773 properties in the NT in 2019-20, to accommodate personnel working at a number of Defence bases, including RAAF Base Darwin, Larrakeyah Barracks and RAAF Base Tindal.
- This reflects 1.9% decrease in total stock compared to the previous year, and below the 10‑year average number of 2,221 properties (Chart 4)
- About 80% of DHA properties are located in Darwin, with the remainder in Tindal and Alice Springs
- The NT accounted for 9.8% of all DHA properties across Australia
- DHA projects in the NT currently under way or expected to commence in the coming years include:
- Breezes Muirhead, located in Darwin’s northern suburbs, which is expected to be completed by 2022, resulting in 1179 dwelling lots, with around 283 dwellings retained for defence members and their families
- Development of the former Lee Point Radar Station, which is expected to result in about 800 residential lots, of which 30% will be allocated for defence members.
Bases and sites
All three ADF services (army, navy and airforce) have multiple northern Australia bases. The army operates from Larrakeyah Barracks and Robertson Barracks; the navy is based at HMAS Coonawarra; and the air force has RAAF bases Darwin and Tindal in the NT.
