A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound Sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.

The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971 when the United States unilaterally terminated convertibility of the US dollar to gold, effectively ending the Bretton Woods system. Many states nonetheless hold substantial gold reserves.
The Australian dollar is the official currency and legal tender of Australia, including its external territories, Christmas Island, Cocos (Keeling) Islands and Norfolk Island, and three independent sovereign Pacific Island states: Kiribati, Nauru, and Tuvalu.

On the introduction of the currency, the $ symbol was intended to have two strokes, but the version with one stroke has also always been acceptable. It is subdivided into 100 cents.

Legal tender is a form of money that courts of law are required to recognize as satisfactory payment for any monetary debt. Each jurisdiction determines what is legal tender, but essentially it is anything which when offered ("tendered") in payment of a debt extinguishes the debt. There is no obligation on the creditor to accept the tendered payment, but the act of tendering the payment in legal tender discharges the debt.

Dynamic currency conversion (DCC) or cardholder preferred currency (CPC) is a process whereby the amount of a credit card transaction is converted at the point of sale, ATM or internet to the currency of the card's country of issue. DCC is generally provided by third party operators in association with the merchant, and not by a card issuer. Card issuers permit DCC operators to offer DCC in accordance with the card issuers’ processing rules. However, using DCC, the customer is usually charged an amount in excess of the transaction amount converted at the normal exchange rate, though this may not be obviously disclosed to the customer at the time. The merchant, the merchant's bank or ATM operator usually impose a markup on the transaction, in addition to the exchange rate that would normally apply, sometimes by as much as 18%.
