The Department of Defence is the department of the Australian Government responsible for national defence policy, supporting the Australian Defence Force (ADF) and ensuring the overall defence of Australia and its national interests. Along with the ADF and other agencies, it forms part of the Australian Defence Organisation (ADO). The Department is accountable to the Parliament of Australia, on behalf of the Australian people, for its spending of public funds and implementation of government policy. Defence staff are primarily based out of the Russell Offices and Campbell Park Offices in Canberra, in the Australian Capital Territory.

The executive head of the department, who leads it on a day-to-day basis, independent of a change in government, is the Secretary of the Department of Defence (SECDEF), currently Meghan Quinn PSM. SECDEF reports to the Minister for Defence, currently Richard Marles.

History Australia has had at least one defence-related government department since Federation in 1901. The first Department of Defence existed from 1901 until 1921. In 1915, during World War I, a separate Department of the Navy was created. The two departments merged in 1921 to form the second Department of Defence, regarded as a separate body.

A major departmental reorganisation occurred in the lead-up to World War II. The Department of Defence was abolished and replaced with six smaller departments – the Defence Co-ordination (for defence policy, financial, and administrative matters), three "service departments" (Army, Navy, and Air), the Supply and Development (for munitions and materiel), and Civil Aviation. The current Department of Defence was formally created in 1942, when Prime Minister John Curtin renamed the previous Department of Defence Co-ordination. The other defence-related departments underwent a series of reorganisations, before being merged into the primary department over the following decades. This culminated in the abolition of the three service departments in 1973. A new Department of Defence Support was created in 1982, but abolished in 1984.

In May 2022, The Canberra Times reported that department had been renamed Defence Australia. However, the department's corporate documents continue to refer to it as the Department of Defence.

The Australian Department of Defence, along with Australian state and other governments, partially fund the Australian Strategic Policy Institute (ASPI), a defence and strategic policy think tank also based in Canberra, Australian Capital Territory.
