A guide to the Australian Dollar

Introduction to the Australian Dollar

The Australian Dollar is the national currency of Australia, known by the abbreviation AUD. Its symbol is the dollar sign ($), which is used domestically, but to distinguish it from other dollar currencies, the Aussie Dollar is usually shown as A$ or AU$.

The Aussie dollar is the fifth-most-traded currency on the forex market – accounting for approximately 6.8% of daily turnover, worth an average value of $445 billion.1 Its popularity is down to the country’s wealth of natural resources, position as a prime trading partner and typically high interest rates.

Economy of Australia

Australia is the world’s biggest island but despite its size, the economy isn’t that large – in fact it ranked just 14th in the world by gross domestic product in 2019.2

The Reserve Bank of Australia (RBA) is the country’s central bank, which oversees issuing currency and controlling interest rates. Typically, the RBA has always been an extremely conservative institution; it doesn’t make many interventions in the currency market and has some of the highest interest rates in the world.

The Australian economy is heavily reliant on natural resources, energy and food. The diversity and abundance of commodities in Australia means it has attracted a high level of foreign investment over the years. There are a huge number of reserves for coal, iron, copper, gold, natural gas and renewable energy sources that bring in companies from all over the world – over 8% of the country’s GDP comes from mining. As an export-reliant country, increases in export prices that exceed the cost in import prices will boost the Australian economy.

What moves the price of the Aussie Dollar?

The price of Australia's currency is counter-cyclical – meaning it doesn’t have a correlation with other currencies – and is incredibly volatile. Here’s what moves the Aussie Dollar’s price:

  • Commodities: most developed economies’ currencies will move in line with each other, largely due to the trade relationships between them. But because Australia's economy is so heavily reliant on commodities, its currency’s price is more closely linked to the price of commodities (metals and grains). This means crop planting, weather, harvests, mine output and metal prices can all have a direct impact on the Aussie Dollar rate. Most other developed economies have a negative relationship with commodities – as higher prices cause higher costs – but for Australia, higher commodity prices create a healthier economy
  • Trade relations: a large percentage of Australian exports go to Asia due to their geographical proximity. This means that as well as commodity cycles, the Aussie Dollar is influenced by demand for natural resources from China, India and Japan. As these economies expand and infrastructure spending is boosted, the Aussie Dollar will rise and as demand from Asia falls, so will the AUD
  • Interest rates: like any currency, the Australian Dollar is impacted by interest rate outlooks. So, any comments made by the RBA about rate changes can play out on the value of AUD compared to other currencies. Typically, Australia’s interest rates have been kept extremely high, which has made AUD a popular currency for carry trades – when forex traders sell a currency with low interest rates, while buying a currency with high interest rates
  • Macroeconomic data releases: important indicators for the health of the Australian currency will move the price of the AUD as traders and investors alter their positions in response to data. Key economic indicators for Australia are the Consumer Price Index, Balance of Trade, GDP and Unemployment Rates

A brief history of the Australian Dollar

The Australian Dollar was introduced in February 1966 and has been through nearly every stage of currency evolution possible: a peg to gold, a peg to sterling, a peg to the US dollar, a peg to a basket of currencies and a moving peg. All these fixed solutions to valuing the Aussie dollar were unsuccessful, and the economy was extremely unstable.

In 1983, the Australian Dollar finally became a free-floating currency, when the government – led by Bob Hawke – decided to abolish restrictions on the international movement of capital. The decision was a crucial part of opening Australia’s economy.

At the time of its floatation, most investment in Australian markets were small domestic banks and companies. But once the AUD was free floating, foreign banks entered the market and boosted the Aussie Dollar to the actively traded currency we see today.

Popular Aussie Dollar currency pairs


AUD/USD is the forex ticker for the exchange rate between the Australian Dollar and US Dollar – the pair is also known as the Aussie. It tells traders how many US$ are needed to buy one AU$ in real time.

The Aussie is the sixth-most-traded currency pair in the world – representing approximately 5% of all forex trades by volume. Thanks to its popularity, AUD/USD is reasonably volatile, which creates a range of opportunities for traders.

Trade volumes for AUD/USD increased following the Australian commodity boom in 2000. As the US became a much more involved trade partner, the relationship between the two countries increased interest in the exchange rate of their currencies. Many traders also use the AUD/USD pair as a benchmark for the relationship that the USD has with commodities and the Asian market as a whole.

The interest rate differential between the two countries has also always been a draw for carry traders – as the RBA keeps interest rates high, while the Fed has typically kept interest rates down.


AUD/JPY is the forex ticker representing the Australian Dollar against the Japanese Yen. It’s an extremely popular pairing for its relation to risk – it tends to fall in price when risk is perceived to be low and rise when risk is higher and market participants are looking for risk-off investments.

Australia and Japan have an extremely close trade relationship. Japan is the second largest importer of Australian shipments, worth approximately $19 billion in 2020 – totalling 9% of Australia’s exports. As with most AUD pairings, AUD/JPY is highly correlated with commodity price changes as Japan relies on Australia so much for natural resources.

The AUD/JPY pair is extremely susceptible to changes in the US economy due to the strong relationship between the Japanese Yen and US Dollar.


GBP/AUD is the currency pair for British Pound Sterling against the Australian Dollar. It tells traders how many AU$ are needed to buy one unit of sterling.

While Britain and Australia are always seen as somewhat connected – due to the Commonwealth – the two economies are extremely different. Sterling is a much bigger currency than the Aussie Dollar, and much more widely traded, which means GBP is more susceptible to speculation.

When trading GBP/AUD, it’s important to be aware that interest rates play a huge role in the exchange rate. This is largely because the 2008 financial crisis led to years of low interest rates for the UK, while Australia was relatively unaffected. So, GBP/AUD is a popular carry trade, which can cause volatility in the parings price.

The best time of day to trade the Aussie Dollar will depend on which pairing you decide to focus on. As a rule, each pair will see the most movement when its sessions overlap. For example, the AUD/GBP pair would be more highly traded when both the Tokyo and London forex sessions overlap.
