Department of Defence
The Australian Defence Force (ADF) is constituted under the Defence Act 1903, its mission is to defend Australia and its national interests. In fulfilling this mission, Defence serves the Government of the day and is accountable to the Commonwealth Parliament which represents the Australian people to efficiently and effectively carry out the Government's defence policy.
The primary role of Defence is to defend Australia against armed attack.
Australia's defence policy is founded on the principle of self-reliance in the direct defence of Australia, but with a capacity to do more where there are shared interests with partners and allies.
