The Australia, New Zealand, United States Security Treaty (ANZUS or ANZUS Treaty) is the military alliance which binds Australia and New Zealand and, separately, Australia and the United States to co-operate on defense matters in the Pacific Ocean area, although today the treaty is taken to relate to conflicts worldwide. Since 1985 New Zealand has been an inactive member of the treaty and the meetings are held only between U.S. and Australian officials. In 2011 a new clause was added to ANZUS, which specifies that it will also apply to cyberspace.
