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 2015 Defence White Paper will align defence policy with military strategy and deliver an affordable Australian Defence Force structure. It will be a whole-of-governement product that reflects the Government's overall strategic, national security, fiscal and broader policy priorities.
