ANZUS Treaty, 1951.
The ANZUS security treaty, concluded in 1951, serves as the foundation of defense and security cooperation between the countries. The Treaty, which enjoys broad bipartisan support in Australia as its pre-eminent formal security treaty alliance, was invoked for the first time—by Australia—in response to the September 11, 2001 terrorist attacks. The two countries signed the U.S.-Australia Force Posture Agreement at the annual Australia-United States Ministerial consultations (AUSMIN) in August 2014, paving the way for even closer defense and security cooperation, and are now working together to advance force posture initiatives under the Agreement. In October 2016 our defense agencies signed a Joint Statement on Defense Cooperation to serve as a guide for future cooperation.
