Protecting the interests of Australia and our people

The Australian Army is the foundation of the nation’s land power. As part of the joint force, it promotes and protects Australia’s interests, deters threats to Australia’s sovereignty and, if necessary, defeats them.

We provide a formidable military capability built upon service, courage, respect, integrity and excellence; combined with the use of cutting-edge weapons, vehicles and military technology.

Adapting to complex strategic environments

The defence landscape is changing at an unprecedented rate, with potential threats coming from areas barely envisaged a decade ago.

As a modern and forward-thinking organisation, the Army is constantly evolving to meet these complex challenges. This includes maintaining our ability to deploy effectively when required to. We invest in the latest military technology, and provide world-class training to ensure all personnel are equipped with the skills to adapt to future strategic needs.
