The official currency of Australia is the Australian Dollar, abbreviated as AUD. The symbol for the Australian Dollar is often represented as A$ to distinguish it from other dollar-denominated currencies. Introduced in 1966 as part of a currency reform, the Australian Dollar replaced the Australian Pound. It has become an important part of both the local economy and international trade. The currency is available in both coins and notes, with colorful designs that reflect Australia's culture and heritage. It is widely used for transactions within Australia and is also traded in global currency markets.
