Northern Territory Defence

Economic contribution | Personnel | Housing | Bases and sites | Further information | Explanatory notes

The NT is in an important part the Indo-Pacific region from an economic and regional stability standpoint, making it a strategic location for defence. With a significant navy, army 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 Defence Strategic Review 2023 reinforced the importance of the Territory to Australia’s national security. This is being supported by the investment of $3.8 billion in northern bases over the next four years.

Personnel

• The number of defence personnel located in the NT decreased by 0.7% to 5,358 persons in 2022-23 (including permanent personnel, reservists and Department of Defence civilians)
• Of the 5,358 defence personnel, 3,319 are in the army, 1058 are in the air force, 762 are in the navy, and 219 are Department of Defence civilians (Chart 3)
• Permanent forces make up 78.0% of defence personnel in the NT
• In line with the decrease in NT defence personnel in 2022-23, the NT’s share of Australia’s defence personnel decreased 0.1 percentage points to 5.0%

Housing

• Defence Housing Australia (DHA) managed 1,710 properties in the NT in 2021-22, to accommodate personnel working at a number of Defence bases, including RAAF Base Darwin, Larrakeyah Barracks and RAAF Base Tindal.
• This reflects 2.1% decrease in total stock compared to the previous year, and below the average of the previous 10 years (2,078 properties)
• About 78% of DHA properties are located in Darwin, with the remainder in Tindal and Alice Springs
• The NT accounted for 10.1% of all DHA properties across Australia
• DHA projects in the NT currently under way or expected to commence in the coming years include:
  • 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 (navy, army and air force ) have multiple northern Australia bases. In the NT, the navy is based at HMAS Coonawarra, the army operates from Larrakeyah Barracks and Robertson Barracks, and the air force has RAAF base Darwin and RAAF base Tindal (Map 1).

Explanatory notes

• The Australian Bureau of Statistics (ABS) does not classify defence as a separate industry for reporting purposes in the national accounts, however it is reported against a number of industries and is predominantly included in the ‘public administration and safety’ industry. Defence personnel numbers are also excluded from the ABS labour force statistics, for reporting purposes.
