Australia was a member of the international coalition which contributed military forces to the 1991 Gulf War, also known as Operation Desert Storm. More than 1,800 Australian Defence Force (ADF) personnel were deployed to the Persian Gulf from August 1990 to September 1991, while contingents from the Royal Australian Navy circulated through the region in support of the sanctions against Iraq until November 2001.
