The logistical support of the multinational International Force East Timor (INTERFET) peacekeeping mission in 1999 and 2000 involved, at its peak, 11,693 personnel from 23 countries. Of these 5,697 were from Australia, making it the largest deployment of Australian forces overseas since the Vietnam War. INTERFET was unusual in that it was led by Australia, casting the country in a wholly unfamiliar role. The logistics and support areas of the Australian Defence Force (ADF) had been subject to deep cuts in the 1990s. The ADF had not anticipated being committed to such a large peacekeeping mission, and was unprepared to support an Australian force projection of this size, much less act as lead nation of an international coalition.
