What You'll Learn

Australian money is backed by the government
Australia's currency is known as the Australian dollar, which was introduced in 1966 to replace the Australian pound. The Australian dollar is legal tender in Australia and its external territories: Christmas Island, Cocos (Keeling) Islands, and Norfolk Island. It is also the official currency in Kiribati, Nauru, and Tuvalu.
The Australian government has the power to legislate with respect to "currency, coinage, and legal tender" under Section 51(xii) of the Constitution of Australia. The government also controls the exchange rate of the Australian dollar, which was floated in 1983 by the Australian Labor government. The exchange rate reflects the balance of payments, as well as supply and demand in international money markets.
While the Australian dollar is not backed by physical assets, it is backed by trust in its value. This trust can be influenced by factors such as interest rates and the actions of investors. Additionally, a small portion of the Australian dollar is backed by gold and forex reserves, with Australian dollar securities also playing a role in backing the currency.

The Australian dollar is legal tender in multiple territories
The Australian dollar is the official currency and legal tender of Australia, including all of its external territories, and three independent sovereign Pacific Island states: Kiribati, Nauru, and Tuvalu. The Australian dollar was introduced as a decimal currency on 14 February 1966, replacing the non-decimal Australian pound. It is subdivided into 100 cents, and the $ symbol precedes the amount.
The Australian dollar is also legal tender in Christmas Island, Cocos (Keeling) Islands, and Norfolk Island. It was formerly legal tender in Papua New Guinea until 31 December 1975 when it was replaced by the kina, and in the Solomon Islands until 1977 when it was replaced by the Solomon Islands dollar.
In addition to being a widely accepted form of payment in Australia and its external territories, the Australian dollar is also the dominant currency in Tuvalu and Kiribati, where their respective Tuvaluan and Kiribati dollars are at par with the Australian dollar.
The Australian dollar is a reserve currency and one of the most traded currencies in the world. Its popularity is attributed to factors such as the relative lack of central bank intervention and the general stability of the Australian economy and government.

Australian money is not backed by assets
Australia's banknotes are produced by the Reserve Bank of Australia, while coins are produced by the Royal Australian Mint. The Australian dollar is legal tender in its external territories, such as Christmas Island, Cocos (Keeling) Islands, and Norfolk Island, and is also the official currency in Kiribati, Nauru, and Tuvalu.
Australia's currency was once backed by gold under the gold standard, where countries agreed to convert paper money into a fixed amount of gold. However, Australia's currency is no longer backed by gold or any other physical commodity. Instead, it is backed by the government, which is known as a 'Fiat' system.
The Australian dollar is not backed by assets but by the trust that it has value. This trust can be influenced by factors such as interest rates and the actions of investors and traders. For example, the Australian dollar has been devaluing over the past 20 years due to various economic factors, including changes in interest rates and the decisions of investors and traders.
While the Australian dollar is not backed by physical assets, it is important to note that currency is still a form of money that holds value and can be used to purchase goods and services. The value of the Australian dollar is influenced by its exchange rate with other currencies, such as the US dollar, and is affected by factors such as supply and demand on international money markets.

Australian money was once backed by gold
Australia, like many other countries, once adhered to the gold standard. Under this system, the total amount of notes that banks could issue was limited by their gold reserves. In other words, money was 'backed' by gold, and countries agreed to convert paper money into a fixed amount of gold.
At the turn of the twentieth century, Australia's currency was a mixture of British coins, Australian coins, and the notes of private banks and the Queensland Government. The first true Australian banknote was produced in May 1913, with additional denominations produced from 1913 to 1915.
In 1966, Australia introduced the Australian dollar as a decimal currency to replace the non-decimal Australian pound. The conversion rate was set at two dollars to the pound. This was also when coins were introduced in denominations of 1 and 2 cents (bronze); 5, 10, and 20 cents (cupronickel); and 50 cents (initially silver, then cupronickel).
In 1983, the Australian Labor government floated the dollar, allowing the exchange rate to be determined by market forces, including the balance of payments, supply, and demand on international money markets.
Today, Australia's banknotes are produced by the Reserve Bank of Australia, and coins are produced by the Royal Australian Mint. The system of money in Australia is a 'Fiat' system, where the currency is not backed by a physical commodity like gold but by the government's directive, which makes it legal tender.

Australian money is available in notes and coins
The Reserve Bank of Australia issues banknotes, while the Royal Australian Mint produces coins. Banknotes account for most of the value of physical money in Australia. Australian banknotes are available in denominations of $5, $10, $20, $50, and $100. Each note has two sides and features important Australians and special Australian designs. The $5 note, for instance, features Queen Elizabeth II on one side, and a new design honouring the culture of First Australians is currently being developed. The notes also vary in size and colour, making it easier to distinguish between denominations.
Australia was the first country to print notes on polymer plastic instead of paper. These polymer notes are cleaner, more durable, and easily recyclable. The first polymer banknote was issued in 1988 as a $10 note commemorating the bicentenary of European settlement in Australia.
Australian coins come in denominations of $1 and $2, as well as 5, 10, 20, and 50 cents. The $1 and $2 coins are gold-coloured, while the 5, 10, 20, and 50-cent coins are silver-coloured. However, none of these coins are actually made of gold or silver; they are made from metals such as copper, aluminium, and nickel. Similar to the notes, each coin has two sides, with a different design on each. One side of the coin features a portrait of Queen Elizabeth II and the year of minting, while newer coins will feature King Charles III. The other side features a unique Australian design and indicates the coin's value. Additionally, each coin differs in size, allowing individuals to distinguish between denominations by touch.
