Book excerpt: This new Defence White Paper explains how the Government plans to strengthen the foundations of Australia's defence. It sets out the Government's plans for Defence for the next few years, and how it will achieve those plans. Most importantly, it provides an indication of the level of resources that the Government is planning to invest in Defence over coming years and what the Government, on behalf of the Australian people, expects in return from Defence. Ultimately, armed forces exist to provide Governments with the option to use force. Maintaining a credible defence capability is a crucial contributor to our security, as it can serve to deter potential adversaries from using force against us or our allies, partners and neighbours.
