The Australian Dollar (AUD), often referred to as the "Aussie," is the official currency of Australia, as well as several of its territories and the independent Pacific island nations of Nauru and Tuvalu. It is one of the most traded currencies in the world and is recognized for its stability and relative strength in the global market. The AUD is commonly used as a benchmark in international trade, particularly in commodities such as gold and iron ore, which are significant exports for Australia.
