Currency of Australia: Australian Dollar
Australian Dollar · AUD · National
Who Issues Australian Dollar in Australia
The Australian Dollar (AUD) is the unit of Australia's domestically run monetary system. Beyond the three-letter code, it is shown with symbol A$ and carries ISO 4217 numeric identifier 036.
For readers comparing AUD, Reserve Bank of Australia manages the monetary framework for the Australian Dollar in Australia. AUD is therefore a nationally administered currency rather than an externally issued unit. The presentation keeps the monetary framework distinct from the conversion quote.
Exchange Rate for AUD
For currency calculations involving Australia, the useful benchmark is a dated AUD observation with its currency pair stated explicitly. The resulting transaction amount can differ once a provider adds its margin or charges. That preserves a clear reference point.
Within Australia's currency framework, compare observations for the same currency pair and a similar timestamp. Reference observations are benchmarks, not guaranteed retail transaction prices. The wording keeps the data layers easy to distinguish.
Banknotes and Coins
Banknotes
The Reserve Bank of Australia identifies five banknote denominations: A$5, A$10, A$20, A$50 and A$100. Australia's current banknotes are polymer.
Coins
The Royal Australian Mint identifies six current circulating coin denominations: 5, 10, 20 and 50 cents, plus A$1 and A$2.
Consumer Payment Methods in Australia
The Reserve Bank of Australia's 2025 Consumer Payments Survey found that cards accounted for 73%* of consumer payments by number, while cash accounted for 15%*. The survey measures the number of payments rather than their value, so these shares should not be compared directly with value-based cashless ratios used on some other country pages.
The remaining 12% covers other methods in the RBA survey after rounding, including internet or phone banking, BPAY, PayPal and other payment types.
