The Australian Dollar (AUD) is the official currency of Australia and its territories. It is abbreviated as AUD and is often represented by the symbol "$" or "A$" to distinguish it from other dollar-denominated currencies. The Australian Dollar is subdivided into 100 cents and is one of the most traded currencies in the world, often used as a benchmark for other currencies in the Asia-Pacific region. The Australian Dollar is issued and regulated by the Reserve Bank of Australia (RBA). It is widely used in international trade, particularly in commodities like gold and iron ore, which are significant exports for Australia. The currency's value can fluctuate based on economic factors, including interest rates, inflation, and global market trends.
